The Only 50 Sailing Terms You'll Need To Know (With Pictures)

Ever get confused by all those odd sailing terms? Starboard, tack, jib… Well, no worries. In this article, I'll go over the most important sailing terms for beginners.

This is a great resource for beginning sailors that need an overview of the most important sailing terms without drowning in it . For a comprehensive list, check out this Wikipedia glossary of nautical terms . There are A LOT of nautical terms there. But no one in his or her right mind will read through that entire page (it has 48.434 words!). There are a lot of obscure words listed that no one really uses anyways. So in this article, I've filtered out the most important ones to get you up to speed quickly. I've also added pictures so you'll know what we're talking about.

Let's jump straight in. For the sake of good manners, I have categorized them by topic. If you are looking for a specific term, just ctrl+f your way directly to it.

Here are the only 50 sailing terms you'll need to know:

Orientation

Parts of the boat, parts related to sails, other terms.

...because it isn't as easy as 'left', 'right', 'front' and 'back'. No, no.

Port is the left side of the boat. It's as simple as that. I'm not entirely sure why don't they just call it 'left' these days. The name came to existence because centuries ago, you always docked your big boat with the harbor (port) being on the left side. And the word stuck with us till today.

Starboard is the right side of the boat. If in a car, you say 'look to your right', on a boat, you say 'look to the starboard'. Again, you might as well just call it 'right'. Oh, wait… you wouldn't seem as cool if you did. Alright, let's keep calling it starboard.

The bow is the front of the boat. The word likely comes from the Middle Dutch 'boech' (nowadays spelled 'boeg'). If you call it 'front' instead, you will get your message across just as well. But it won't get you the admiring looks from those around you.

Stern is the back of the boat. That is where you, as a captain, will spend most of your time. Whether you will force your crew to call it 'stern' or let them use the word 'back', like the dry land creatures they are, is up to you. After all, you are the captain.

The windward side of the boat is the side facing into the wind. So if the wind is coming from the right side, the windward side is on the right. Unlike some of the previous ones, this term actually makes sense - at times you need to talk about a direction not fixed in relation to the boat, but rather relative to the direction of the wind.

Leeward side of the boat is the lee side. If the wind is coming from the right side, the leeward side is on the left. Note that neither windward nor leeward specify the angle of the wind. Thus even if the wind was coming 20 degrees right off of the direction of the boat, so almost from the front, left would still be considered the leeward side.

Since there are gadgets and parts on the boat that you won't see anywhere else, it only makes sense they all have their own special name. You want to know these because unlike the direction terms where you can do with 'left' and 'right', you don't want to call a tiller 'that stick thing back there'.

Helm is the boat's steering wheel. In this case, I forgive those who came up with this name, since it is shorter than 'steering wheel' and thus saves valuable time that we can spend on sailing. Though I doubt linguistic economy was the reason.

Tiller is the long stick that operates your boat's rudder. A steering stick, if you will. It has the same function as a helm does, but it is usually used on smaller boats, where a helm would take up too much space. Or by people who prefer it to a helm, since a tiller offers a bit more in terms of response.

The rudder is the long, flat piece of metal or wood that sits underwater below the back of your boat. Connected to a tiller or a helm, it is used to control the direction of your exciting voyage. By the way, since aerodynamics and hydrodynamics work in similar ways, a plane is also operated by a rudder. Though that one isn't underwater. Hopefully.

Hull is the boat's body. Whatever the shape or size, whether opened on top (like a dinghy) or closed by a deck, (like a traditional sailboat) it's all called a hull. Structures sitting on top of the deck, like a deck salon or cabins, aren't considered a part of the hull anymore.

The keel is an underwater fin below the boat's belly. The sizes and shapes vary, sometimes it is relatively short and goes deep, (fin keel) sometimes it runs from the front all the way to the back (full keel or ballast keel). It is there mainly for stability and to help maintain forward direction when sailing.

The cockpit is the area where a boat is operated from. On sailboats, it is usually in the back and it is an open area without a roof, though this varies. You will find the rudder control and winches there. In 'smaller' (below 70 ft or so) sailboats this area oftentimes doubles as a deck dining place with a table and seating.

The bimini is a sun roof or shade that is covers the cockpit, and is generally attached to a steel frame which runs over the cockpit.

This is where things tend to get confusing. There are a whole lot of parts and a whole lot of names for them. It pays off for you and your crew to know them though, as during the stormier moments, you all want to be on the same boat (ha, ha) linguistically, as every second counts.

Lines are ropes. Not much more to add here. I suppose a 'line' sounds a bit fancier than a 'rope'. One thing this article will teach you is that if there is the slightest crack in the wall of your boat, linguistic elitism will leak its way in.

This one is quite self-explanatory. The mainsail is the main, largest sail of the boat, attached to the mast on the side and the boom at the bottom. It has a triangular shape and serves as the most important sail, the first one you should get acquainted with if you are just starting out.

The jib is the front sail of your boat, sometimes also called the genoa. That is as long as you are sailing on the traditional sloop - the classical two sail setup you see the most often. The jib is wrapped around the line that goes from the top of your mast to the boat's bow.

Spinnaker is the third type of sail you are the most likely to encounter on your travels. It goes in front of your boat and has a half balloon or kite-like shape. This is because it is constructed specifically for sailing downwind. Its purpose is to grab as much backwind as it can and drag your boat forward. It is not attached to the boat most of the time like the mainsail or the jib, instead, it is stored separately and used only when needed.

The mast is the tall, vertical pole that goes from the floor of your salon, through the deck, meters above your boat. All the sails are attached to it, also radars and lights, giving sailboats radio and visual visibility far greater than that of equally sized motorboats. Take that, ya noisy stinkies!

The boom is the horizontal pole right above the deck, attached to the mast at the right angle. The bottom of the mainsail is attached to it, it is used to determine its shape and direction. It is also where the mainsail is often stored, folded and covered with a protective sheet. The boom is also among the top causes of injuries on a sailboat, as in certain winds it tends to swing with force powerful enough to knock a few grown men overboard. Stay away from its reach at all times when under sail.

The forestay is the cable going from the top of the mast to the very front of the bow. It is there to hold the mast in place. Sometimes you will find people refer to it as the 'headstay'. It is often made of steel, so it is safe to hold on to it when you are pretending to be Jack on the bow of the Titanic's, the boat hits a wave and you lose your balance.

This diagram is from our guide on sailboat parts , which I really recommend for beginners. It walks you through all the most important sailboat parts in normal words.

The backstay is the cable going from the top of the mast to the very back of the boat. In many cases it is doubled at the bottom, each end attached to one corner of the back of the boat so that they don't interfere with space and provide more stability for the mast. Just as with forestay, these are made of steel.

Shrouds are the cables going from the top of the mast to the left and right side of the boat. Sometimes there are four, two on each side. Together with forestay and backstay, they make sure your mast withstands all the forces exerted on it when the wind pushes the sails.

The foot of a sail is its bottom edge. If you imagine a sail as a triangle, the base is called the foot. You probably won't use this term while sailing, but when researching proper sail trim, it is likely you will stumble upon it.

This diagram is again from our guide on sailboat parts , which I really recommend for beginners. If you're looking for a good starting point to learn your sailboat ins and outs, this article is perfect for you.

Leech of a sail is its back side edge. Thus it is the part closest to you when you are standing at the helm. Just as with the foot, this is a term quite often used when describing sail trimming techniques, since the shape of the leech determines the shape of the whole sail.

Luff of a sail is its front side edge. Thus the part the furthest from you when you are standing at the helm. For mainsail, it is the edge that is right next to the mast, for the foresail it is the edge right next to the forestay. Just as with foot and leech, the shape of these edges determines the overall shape of the sail so you will most likely encounter these terms in trimming lessons and tutorials.

The head of a sail is its top corner. On a traditional sloop, you will have the 'main head' and the 'jib head'. There is usually a reinforcing patch of some kind on these corners, as you will find a hole in them to which a line is attached.

It's also something else entirely, but more on that later ...

Halyard is the line attached to the sail head. On your boat, you will most likely have two. The 'main halyard' which is what you use to hoist your mainsail if it is folded on the boom, and the 'jib halyard' which holds the jib head up.

Clew of a sail is its back corner. The line attached to the 'main clew' will be used to hoist your mainsail if it is wrapped inside of the mast. The line attached to the 'jib clew' will be used to open the jib on most sailboats since jibs are most often wrapped around the luff.

Telltales are light, usually cotton or wool pieces of ropes attached to a sail, showing you the airflow around it. These are important because they help you determine if your trim is effective or not. Because of the material they are made of, you might sometimes encounter them being called 'woolies'.

Vang, or a 'boom vang' is a device pulling the boom down. This is important because it controls the tension of the mainsail, influencing its shape greatly. You won't find it on every boat though. Holiday cruisers often don't have it, as it is a piece of equipment focused on performance and thus not necessary for your average trip.

Topping Lift

The topping lift is a line that is attached to the aft (back) end of the boom and runs to the top of the mast. It supports the boom whenever you take down the mainsail.

Also referred to as a 'horse', the traveler is a side to side track to which the boom is attached, allowing the control of the extent to which the boom goes off the centerline. This is important especially if the wind is blowing from behind and you need to control the angle of the mainsheet.

Outhaul is the line attached to the mainsail or the jib clew, allowing the control of the foot tension. This is important for determining the sail shape - for instance in stronger winds, you want the foot to be more tense to achieve a more effective airflow as opposed to slower winds where you can allow the foot to arch more.

Reefing is reducing the sail area to lessen the power exerted on it by the wind. You may want to reef if the wind is getting too strong for your boat, or if it is changing too rapidly, as an overpowered boat is difficult to control. Fun fact: they say that when you feel you need to reef because the wind got too strong, it is already too late to reef.

A batten is a slat placed horizontally in the body of the sail to support its shape. You will not find them on all sailboats, it is a performance-enhancing element that many cruisers lack. It helps tremendously as without it, sails tend to belly out and lose their shape under certain conditions.

The cleat is a piece of fitting where a line can be secured and immobilized, even if under great tension. It usually consists of two cogwheel-like pieces fastened close to each other, in the middle of which the rope is placed, unable to move thanks to friction. This type is great as it allows for a quick release. Sometimes though, it is a simple piece of metal or plastic where the rope is tied.

...and then there are all those things that just float around you when sailing, those little things that are the reason for you having to carry a dictionary in your pocket.

Fenders are bumpers allowing some contact with other boats or piers while docked, without scraping the paint. They are often balloon-shaped, made of rubber or some relatively soft material. They are usually attached to the boat's railing and you move them around as you need.

The beam is the width of the boat. Could be just called width, I know. The word comes from the fact that there are transverse reinforcing beams in the boat hull and deck. Next time you are choosing your charter boat for holidays, you will know what this attribute means.

True wind is the actual direction and speed of the wind. This is different than the apparent wind, which is wind direction and speed relative to the boat. Apparent wind is a combination of the true wind and the headwind, which is the wind the boat experiences solely by being in motion.

The berth is a sleeping space on a boat. Thus if a boat has eight berths, it means eight people can comfortably sleep on it. Note that this often includes the salon couches, so a berth is not necessarily a space in an actual bed for one person.

Boat's draft is the distance from the water surface to the deepest point of the boat. In other words, the draft is the minimum water depth you can go to and not scrape your hull or keel. Better double this number when sailing, just to be safe, as hitting the seabed can have disastrous consequences.

Tacking is zig-zagging towards your destination. It is necessary in case your destination is in the direction of the wind since sailboats can not go directly into it. Since the closest to the wind direction you can sail is around 45 degrees, you have to change direction left and right from your desired course.

This diagram is from our guide on sailing into the wind for beginners , which explains in 7 simple steps how to get good upwind sailing performance.

Bareboat is a boat without a skipper. You will encounter this term in boat charters and it means you rent the boat without any crew, thus you need to operate it yourself. It is the best way to sail unless you enjoy living in close proximity to a sea wolf who you also have to feed.

The chart is a nautical map. It differs from classical maps as it depicts information relevant for a sailor - water depth, navigational hazards, seabed material, anchorages and so on. Formerly made of paper, these days made of ones and zeros. As is everything in this digital world.

We have a guide that explains all the different chart types clearly for beginners - read it here .

Galley on a boat is its kitchen. Also a medieval warship, but if you find this term in a boat's description, war is not likely what they have in mind.

Heads on a boat is the bathroom. Though in all my years of sailing I have never ever heard anybody use this term instead of a 'bathroom'. I suppose saying that you are going to use the heads just sounds odd.

A knot is the unit of speed of boats. It is equal to one nautical mile per hour. That is 1.852 kilometers per hour or 1.5078 miles per hour. Though a bit confusing and annoying at times, you will have to get used to this, since most of your boat's instruments will use this unit. It dates all the way back to the seventeenth century when boat's speed was measured with a rope with knots tied on it.

Mooring is attaching the boat to a buoy that is anchored to the seabed. This is usually a cheaper option to docking in a marina. It also means larger space between the boats anchored in the same area, thus more privacy. Though you will have to use your dinghy to get to shore instead of just stepping on the pier directly from your deck.

A salon on a boat is its living room. On smaller boats, it is usually in the same room as the boat's kitchen and the captain's corner with navigation instruments.

A skipper is the captain of a sailboat. If you ask me, the word 'captain' is much better than a skipper, which to me sounds like a small boy who sits on the shore the whole day, skipping stones. But hey, who am I to talk.

A monohull is a classical boat with a single hull. A boat with two hulls is called a catamaran, or a 'cat'. Although rare, there are also trimarans, boats with three hulls. Multihulls with four or more hulls do happen but they are an unnecessary freak of nature.

So there you have it. Fifty sailing terms you will encounter the most when traveling or learning. I know you might think some of them are a bit unnecessary since they have a perfectly fine 'real world' equivalent. I agree. But until the tradition changes, you might want to get some of these under your skin.

A boat's freeboard is the distance from the upper deck to the waterline. Classic yachts have low freeboards, so they appear to lay deeper in the water, as opposed to more modern yachts, which have a higher freeboard. It literally means 'free-board' : the amount of visible board.

The lunch hook is a light anchor setup that is used to moor small yachts temporarily. It typically uses a lightweight anchor on a short scope that takes little effort to set. The lunch hook is only used when the crew is on board and will be monitoring the anchor.

In naval architecture and ship design: “Head” = WC = Bathroom. A toilet is still a toilet. The toilet is in the head. In olden day, the toilet was a hole in the head.

Hi Rich, you’re absolutely right. I’ve corrected the error. Thanks for pointing it out.

A nautical mile is one minute of a degree, so if you travel 60 nautical miles that means you have gone 1 degree around the “globe”. (Note: arc length not actual length.) This is the original definition. As such the average was agreed upon and the lengths given a standardization. Which you mentioned.

As such 1 knot is to travel one nautical mile in an hour.

Also 1.5078. I think you made a mistake as it should be 1.1508 miles to a nautical mile.

Thanks for the information. Sorry about being a pedantic mathematics teacher.

So, where is the “nautical mile” calculated from, the equator or one of the tropic lines?

Just to clarify a nautical mile. If you draw an imaginary line from the North Pole or South Pole to the center of the Earth and draw another line from the center of the Earth to any point on the equator, it forms a right angle, which is 90 degrees. This equates to latitude. The equator is 0 degrees and the poles are 90 degrees. Your latitude is the angle that you are north or south of the equator. Each degree of latitude is divided into 60 minutes. A minute of latitude is the same distance matter where you are on Earth. It is 6,076 feet. This is the length of a nautical mile. A statute mile is 5,280 feet, so a nautical mile is 1.1508 statute miles.

Thank you very clear and well explained. Hopefully I’ll remember The Fifty

KöhnSharkösz

Really? No gunwale? No transom? Those or basic terms to the Washington State Boater Education Card required to operate watercraft here. Definitely more of a “need to know” than bimini.

Thank you, those definitions and explanations were clear, thorough, and helpful. I’m really glad I found my way (somehow) to your webpage.

• Glossary: essential terms a sailor should know

We have put together a comprehensive list of essential sailing terms to enhance your nautical knowledge. Delving into diverse areas such as meteorology, navigation, and boat equipment, our glossary covers sail types, boat components, and crucial units of measurement and abbreviations that every sailor should be familiar with. Plus, you'll find terms unique to charter boats, the boat rental process, safety at sea, signalling aids, and modern sailboat technology.

Anchor windlass is a mechanical device used to hoist and lower the anchor and its chain on a boat. It operates under high tension and typically has its own circuit breaker to protect it from electrical overloads. When using an anchor windlass, it is essential to allow for short breaks during operation to prevent it overheating and any resultant damage to the equipment.

Anticyclone is an area of high air pressure.

Apparent wind is the wind we perceive when we are on board and results from the vector sum of the real wind and the wind generated by our motion while sailing. The topic of apparent wind is covered in detail in our article — Apparent vs. true wind .

Autopilot is a device designed to steer a boat along a predetermined course. It independently adjusts the rudder as required, ensuring the vessel follows the set path to its destination as accurately as possible. 

Baby net or safety net is a safety feature that prevents small children from falling off the deck into the water. It is a net similar to a fishing net, which is installed along the boat's railings. A baby net does not come as standard with a rental boat, so always discuss it with the salesperson when booking if you want to order the net from the charter company. We discuss safety features in our article — Sailing with kids: how to keep all of you safe and happy .

Safety nets on the boat effectively prevent children from falling into the water.

Barber hauler is a sail control device used to adjust the angle of the jib or genoa sail in relation to the wind, mostly found on more sporty boats. It consists of a line or tackle system attached to the clew of the sail, allowing sailors to fine-tune the sail's position for optimal performance and improved windward efficiency.

Bathing or swim platform , is a foldable structure located at the stern of a boat, providing easy access to the water for swimmers or during training activities. When sailing, it is advised to keep the bathing platform closed and secured in place, rather than left extended.

Batten is the reinforcement in the mainsail. Mainsails are generally classified based on their shape and construction, with variations such as full-batten, partial-batten, or no-batten mainsails.

Beaufort scale  is a widely recognized scale in the sailing world. It categorizes wind forces and their corresponding effects on sea surface conditions, allowing skippers to estimate wind strength visually. By observing the behaviour of the sea surface and the wind's impact on it, sailors can use the Beaufort scale to make informed decisions about their sailing course and speed.

Bearing compass is a type of compass that is used to determine the bearing, or direction, of an object or location relative to the compass itself. It is commonly used in navigation to determine the direction of a distant landmark or to maintain a specific course while sailing.

Bimini  is an alternative term for a sun canopy that provides shade for the helmsman's station and the rear portion of the cockpit. In the rain, it serves as a slight protection from the water. Often, however, sailors fold it up for sailing, and sometimes there is no other way to do it, as the mainsail sheet passes through it.

Boom is a horizontal spar, typically made of aluminum or carbon fiber, that attaches to the mast and holds the foot of the mainsail. It runs perpendicular to the mast and is held in place by a combination of topping lift, mainsheet, and outhaul.

Bora is a powerful, cold wind originating from the north to north-east that frequently affects the Adriatic Sea. It can pose a significant risk to sailors navigating the region. To learn more about the Bora and its impact on sailing in Croatia, check out The Bora: the scourge of the Adriatic .

Bow thruster  is a mechanism located at the bow of a vessel that assists with maneuvering while in port. It is not intended to replace the main engine and should not be used while sailing. The primary function of a bow thruster is to help shift the boat's bow to port or starboard. It's essential to operate the bow thruster with caution, as it has a high voltage. Use short, intermittent presses (2-3 seconds) rather than prolonged holds to prevent the bow thruster from burning out and becoming inoperable.

Bowsprit is a spar that extends from the bow of a sailboat. It is used to attach the forestay, which supports the mast, and to extend the sail area forward. On historic ships it is slightly angled upwards towards the sky. On more modern boats it extends straight out from the bow and may be retractable or foldable to make docking and storage easier.

Brackish water is water that is neither salty like the sea nor fresh like freshwater streams. Its salinity is somewhere in between. It is most often found at the mouths of rivers or in lakes by the sea.

Breeze is a periodic wind phenomenon caused by differences in air temperature between day and night. According to the time when it occurs, it is distinguished between day (sea) and night (land). The breeze is a beautiful sailing breeze. Read more about breezes in our guide — Understanding land and sea breezes: how they can affect your sailing .

Buoy field  is an arrangement of multiple buoys within a bay, anchored to concrete blocks on the seabed. Typically, a fee is charged by the operator for using these buoys, but the cost is generally lower than docking at a pier or marina.

Cardinal marks are navigational aids that indicate the location of safe water relative to a hazard. They are named after the four cardinal points: North, East, South, and West.

Cardinal marks

Charter company owns the boats that are available for rental and acts as a partner to businesses like ours. We feature their boats in our search portal .

Check-in is the process of taking over a charter boat. You can find out more about what you need to look out for in our guides Boat check-in: examining a yacht down to the last screw and Inspecting your rental boat: a complete checklist and guide

Check-out is the handing over of the boat to the charter company at the end of your yacht charter holiday.

Cirrus clouds are characterized by their wispy, hair-like appearance, resembling algae, tufts, or manes. These clouds are translucent, cast no shadow of their own, and have extremely fine fibres.

Cleat  is a metal object attached to the deck of a boat used to secure the boat. It may also be on a pier.

Cleats can also be found on the pier.

Cockpit is an area towards the rear of a sailboat, typically designed for the crew to steer, navigate, and control the boat. It is the central location where the helm, rudder, and various lines, winches, and controls for sails are accessible.

Code Zero is a unique sail that isn't found on all sailboats. It is similar to a larger, deeper genoa but made from a lighter material. The sail is equipped with its own furling line and endless loop for easy deployment and storage.

COG (Course Over Ground) refers to the direction of a vessel's movement measured in relation to the earth's surface or the seabed.

COLREG  is a shortened term in English that stands for the Convention on the International Regulations for Preventing Collisions at Sea. These regulations provide rules for watercraft operation, ensuring clear right-of-way guidelines.

Cumulus clouds are generally puffy and white, with a flat base and a rounded top. They can have a cauliflower-like appearance, and their edges may be well-defined or fuzzy. 

Cunningham is a type of rope that runs from the base of the mast to the lower edge of the mainsail, allowing the sailor to stretch the edge of the sail downward. It is typically located on the side of the mast that is opposite to the outhaul.

Cyclone is an area of low air pressure.

Dew point  is the temperature at which the air becomes saturated with water vapour and begins to condense into dew.

Dinghy , also known as a tender , is a small boat often used by sailors to transport themselves and their supplies to and from their anchored or moored boat. Dinghies can be inflatable or made of hard materials like fiberglass or aluminum.

Dodger,  also known as  sprayhood,  is a protective structure mounted at the front of the cockpit on a sailboat. It shields the cockpit and companionway from wind, spray, and waves, providing shelter and improved comfort for the crew

EPIRB (Emergency Position Indicating Radio Beacon) is an emergency distress beacon that is used to transmit a distress signal to rescue authorities in the event of an emergency situation

Fender is a cushioning device made of rubber, plastic or foam that is used to protect a boat's hull from damage when it is moored against a dock, pier or another vessel. 

Flare is a signalling device used to call for help in an emergency. Its misuse is punishable.

Fog horn is a signalling device that produces loud, low-pitched sound blasts to warn other vessels of the presence of your boat in conditions of reduced visibility, such as fog or heavy rain.

Foil is a hydrodynamic device that is used to lift the hull of a boat out of the water and reduce drag. Foil technology is also used in other water sports such as windsurfing, kiteboarding, and wingfoiling.

This is what a foil looks like on a racing catamaran.

Gangway is a temporary bridge or walkway that connects a boat to a dock, allowing people to move between the two structures.

Gennaker is an additional sail that is similar to a genoa. It is made of lighter material, which makes it ideal for lighter winds. Gennakers often have distinctive colours, and there are several reasons why sailors might want to rent and try one out.  Check out our 5 reasons to rent a gennaker .

Genoa , also known as genoa jib , is a type of sail that is positioned forward of the mast and is used on sailing boats. It typically covers the area from the mast to the bow of the boat, and is larger than the mainsail. It can range in size from 100% to 150% of the foretriangle, which is the triangle formed by the mast, forestay, and deck.

GPS , which stands for Global Positioning System, is a satellite-based navigation system that provides location and time information anywhere on Earth. Sailors can use an electronic GPS device to accurately determine their position on the water.

Gulets are double-masted boats designed and built based on traditional Turkish wooden sailing boats. One of the typical destinations for gulets, which we also offer, is Turkey.

Gybe or jibe is a sailing maneuver where the sailboat's stern is turned through the wind to change the wind direction from one side of the boat to the other, usually while sailing downwind. The boom of the sail swings across the boat during a gybe, and it should be performed carefully to prevent accidents and damage to the boat and crew.

Harness is a safety device used in sailing that is attached to a sailor's body or life jacket and secured to the boat's deck with a buckle to prevent falling overboard.

Halyard  can is a rope used to raise different types of sails such as the mainsail, jib, genoa, spinnaker, and gennaker. Each sail will typically have its own dedicated halyard to hoist it up the mast.

Hatch is an opening on the deck or cabin top of a boat used for ventilation, access, or as an emergency exit.

Horseshoe life buoy is a U-shaped buoyant device made of foam or other buoyant material, and is used as a safety device in the event of a person falling overboard. It is typically kept on board a boat, often near the stern on the railings.

Impeller is a small component (propeller) in the engine that provides suction and circulation of seawater in the engine cooling. Because it is such a crucial component, you will usually find a spare one on board.

Isobar is a line on a synoptic chart that connects two points where the atmospheric pressure is the same.

Isolated hazard refers to a navigational mark or buoy placed in the sea to indicate a potential danger, such as a shoal, rock, or other underwater obstruction located in open water. While it is possible to sail around an isolated hazard, it is generally recommended to maintain a safe distance by navigating around it in a larger arc.

Isotherm is a line connecting two points of the same temperature.

9 essential sailing knots

Jib is the term for a headsail that fills no more than 100% of the area between the forestay and the mast.

Jugo , also known as Sirocco , is a moody and unpredictable south to south-easterly wind found in the Adriatic. Find out more about it in our guide — The Croatian Jugo wind: when and where it occurs and why to be on the lookout! !

Keel , which is the heaviest component located beneath a boat and has the lowest center of gravity, plays a vital role in maintaining the vessel's stability. It typically accounts for up to 40% of the boat's weight and can have a fin or bomb shape. The keel's primary purpose is to stabilize the boat and prevent it from capsizing by helping to restore it to a horizontal position when it is tilted due to wind or waves.

Kicker , also known as a boom vang or vang , is a mechanical device consisting of ropes or a piston that is connected between the deck, boom, and the base of the mast. It is used to control the shape of the mainsail by adjusting the tension on the leech of the sail and controlling the boom's vertical position.

Knot can be the one on the rope or also a unit indicating the speed of the boat. It's equivalent to 1.852 kilometres per hour.

Lazy bag (sometimes called a lazy pack  or stack pack ) is a large cover designed to store a folded mainsail on the boom.

The lazy bag is attached to the boom and the mainsail falls into it when it is folded.

Lazy jacks are lines holding the lazy bag.

Leech  or  leach is the back edge of the sail.

Libeccio or Lebić  is a south-westerly to westerly wind and is typical of northern Corsica, the coast of France, Italy and also the Adriatic, where it usually arrives just after the Jugo/Sirocco. Read more about this wind in our article — The Libeccio/Lebić: a stubborn, unpredictable wind .

LOA  stands for  Length Overall , which is the maximum length of a vessel measured from the foremost point of the bow to the aftermost point of the stern, typically along the waterline.

Logbook is a document where a sailor writes down details of a voyage including weather, the boat's course, position and other information.

Mainsail , sometimes also referred to colloquially as the "main," is the sail that is hoisted up the mast of a sailboat.

Mainsheet track or traveller  is the rail on which the   mainsheet car or block moves back and forth, allowing for adjustment of the angle of the mainsail relative to the wind. Racing boats typically have the mainsheet track located in the cockpit for maximum adjustability, while recreational sailboats may have it located closer to the mast.

Marina is just another name for a harbour for recreational boaters. A marina often has social facilities, a shop, offices of charter companies, etc.

Marinero is a Spanish term for a marina worker who assists with various tasks, such as helping boats to dock and providing assistance to boaters with any issues or needs they may have while in the marina.

Mast is a tall vertical spar that supports the sails on a sailing vessel. It is typically located in the center of the boat and is stepped (or mounted) on the keel or deck. The mainsail is hoisted up the mast and attached to it, while the jib or headsail is usually attached to the forestay, which is a cable or wire that runs from the top of the mast to the bow of the boat. 

Meltemi  is a dry northerly wind that occurs mainly in the Aegean and eastern Mediterranean, from late May to late September. Read more about this wind in our guide — The Greek Meltemi: friend or foe? .

Mistral  is a cold wind found, for example, in France. It works on a similar principle to the Croatian bura. For more information, check out our article — The Mistral: a turbocharger for experienced sailors .

MOB stands for Man Overboard , which refers to the emergency situation where a crew member has fallen into the water and immediate action is required to retrieve them. Find out more in — Man Over Board (MOB): a step-by-step guide .

Mooring  can refer to any type of permanent anchor or buoy to which a boat can be tied up .  Commonly on the Adriatic, it consists of a concrete block on the bed and a rope leading to shore. The boats are then moored to it at the pier or jetty. It is a very convenient and easy way to moor a boat.

Mooring bollard  is a sturdy vertical post or pole, often made of metal or wood, that is used as a mooring point for boats.

Bollards serve both recreational boats and transport or cargo ships. Therefore, it is often large in size.

Mooring hook is pole with a hook used by boaters to grab onto a mooring buoy or other floating object in the water and retrieve the mooring rope attached to it.

Nautical flag alphabet (International Code of Signals) is a special set of characters, words and flags that sailors around the world use to communicate.

The nautical alphabet is also used in aviation.

Nautical mile is a unit of distance at sea. 1 NM equals 1.852 m. But be aware that it differs in length to a land mile!

Occluded front  is a type of weather front that occurs when a fast-moving cold front overtakes a slower-moving warm front. This results in the warm air being lifted off the ground and creating clouds and precipitation.

Offshore typically refers to sailing or boating in open water, away from the coast or shore. This type of sailing can involve more challenging conditions and requires greater skill and experience. Read more about it our article — Beyond the shoreline: 10 things to consider when offshore sailing .

Outboard engine or outboard motor is a small portable engine designed to power a dinghy. It is ordered as an extra with the boat rental.

What the seagull's sitting on is an outboard motor.

Outhaul is a control line on a sailboat that adjusts the tension of the mainsail foot, which is attached to the boom. It allows the sailor to control the depth and shape of the mainsail along the boom.

Plotter is an electronic device used for navigation that displays and tracks the boat's position and movement using GPS technology. It is often located in the cockpit.

Port (side) is the term for the left-hand side of the boat when facing forward.

Porthole  is a term for a small, usually circular window on a boat or ship.

Preventer  or boom preventer is an auxiliary line or rope that is rigged from the end of the boom to a sturdy point on the deck, mast, or other secure attachment point on the boat. The purpose of the preventer is to restrict the boom's movement and prevent an accidental or unintentional jibe, which can happen when sailing downwind or on broad reach courses.

Propeller is a device consisting of blades that rotate to provide propulsion for a boat's engine. It is often located at the stern (back) of the boat and is powered by the boat's engine.

Propwalk is a phenomenon that occurs when a boat's propeller produces a lateral force that causes the boat's stern to move to one side when the engine is in gear. This is particularly noticeable at slow speeds and when maneuvering in tight spaces, such as a marina or dock.

Propwash is the turbulence created by the rotation of the propeller. Propwash deflecting off an angled rudder allows even large boats to turn in a tighter space.

Quebec flag signal (yellow) in the International Code of Signals means "My vessel is healthy and I request free pratique" which is a signal made by a ship entering port to request permission to enter and clear customs and immigration. It is usually used when sailing abroad. To learn more about crossing borders, take a look at Can you cross national borders with a charter boat?

Reefing  is a technique used to reduce the area of the sail in order to maintain control of the boat and prevent it from being overpowered in strong winds. Charter boats usually have 2 or 3 degrees of reefing available.

Railing  is another term for the guardrails around a yacht.

Rigging refers to the system of ropes, wires, and hardware that support and control the sails and masts on a boat or ship. It includes not only the mast, boom, and standing rigging (wires or rods that support the mast), but also the running rigging (ropes that control the sails), such as halyards, sheets, and control lines.

Rudder blade is the part of the steering system that is underwater. A boat may have one or two rudder blades.

Safety line is a line running along the deck of the boat by which sailors fasten their harnesses to prevent them from falling into the water when the boat is heeling or in large waves. The safety line is not automatically installed on the boat and must be installed separately.

Self-tacking jib is a type of headsail that is specifically designed to tack without the need for adjusting the sail position or manually pulling on the sheets. The sail is attached to a track or a traveler that runs athwartships on the boat and allows the sail to pivot and change sides without having to be moved or adjusted manually.

Shackle is a small metal device used to attach a line to a sail. It is used to connect the sail to the halyard or other lines on the boat. It can also be used to connect different sails together or to connect a sail to a spar or other structural element of the boat.

Sheet is a rope or line used to control the angle and shape of a sail. There are different sheets for different sails, such as the mainsheet for the mainsail, the jib sheet for the jib sail, and the spinnaker sheet for the spinnaker sail.

Shrouds are actually a type of standing rigging, which are the fixed lines or wires that support the mast of a sailboat. They run from the mast to the sides of the boat, and help to keep the mast upright and stable.

Spreader  is a horizontal strut that extends from the mast to the side of a sailboat, providing support for the mast and helping to spread the shrouds that support the mast.

Spinnaker pole  is a long and sturdy pole used to hold the clew (bottom corner) of a spinnaker sail out from the mast of a sailing boat.

Steering wheel is the device used to control a boat's direction. It is connected to the rudder blade through a steering mechanism. Boats can have one or two steering wheels depending on size and design.

Storm sails are special sails, usually orange in colour, whose small surface area and strong material allow sailing in storms. The sails are not installed on the boat all the time, they need to be unpacked from the hold when needed. Ask at check-in where the storm sails are located on the boat.

Storm sails often have a distinctive colour.

Skipper is just another name for the captain, the skipper of a yacht. Would you like to become a skipper too? Take a look at our sailing courses .

Spinnaker is a large, lightweight and often colourful sail that is designed to be used when sailing off the wind, such as on a reach or a downwind leg.The spinnaker is attached to the boat's mast and is supported by a spinnaker pole.

Spin-out refers to a situation in which a boat, while sailing downwind, loses control and starts turning towards the wind.

Sprayhood is a protective covering, typically made of canvas or other durable material, that is installed over the companionway (entrance to the cabin) of a sailboat. Its primary purpose is to shield the cockpit and the interior of the boat from wind, spray, and rain while underway

SRC stands for Short Range Certificate , which is a certification required for operating a marine VHF radio.

Starboard is the term used to describe the right-hand side of a boat when facing forward.

Stay is a term used to refer to a piece of rigging that helps support the mast of a sailing vessel. It typically runs from the top of the mast to the bow of the boat, forming a triangle shape along with the mast and the boat's deck.

Stratus is a type of low-level cloud characterized by its uniform, featureless appearance that often covers the entire sky.

Synoptic map , also known as a weather map, is a graphical representation of current weather conditions created using data collected from weather stations, satellites, and other sources.

Tack is the maneuver of turning the sailboat against the wind.

Telltales are pieces of yarn or fabric that are attached to a sail, stay, or rigging on a sailboat. They are used as a guide for trimming or adjusting a sail by providing information about the airflow around the sail.  

Telltales on a sail

Tender is another word for dinghy.

Tiller is a rod used to move the rudder blade and control the direction of the boat. It is often used on smaller sailboats instead of a steering wheel. In case of an emergency, there might be a spare tiller onboard as a backup.

Topping lift  or topenant is a line that runs from the end of the boom to a point high on the mast, which supports the boom and prevents it from dropping too low when the mainsail is not raised.

Trade wind is a wind that blows steadily towards the equator from the northeast in the Northern Hemisphere and from the southeast in the Southern Hemisphere, usually found in tropical regions.

Transom is the reinforced vertical portion located at the stern of a boat. It connects the sides of the boat, giving it form and structure. The transom is also where an outboard motor is typically attached to the vessel and where the boat's name may be painted.

True wind is the actual wind that exists in the environment and is not affected by the motion of the body or the vessel. It is the wind that would be felt if the vessel were stationary.  Find out more in our article — Apparent vs. True Wind .

We found nothing for this letter except in the nautical alphabet (U: Uniform – you are heading into danger). If you can think of something to go here, get in touch.

Venturi wind is a localised wind flow originating and blowing out of a strait, for example between hills or rocks.

VHF  (short for Very High Frequency ) is electromagnetic waves that allow radio communication between ships, aircraft, ports, etc. 

Winch  is a mechanical device consisting of a drum that rotates either manually or powered by an electric or hydraulic motor. The rope or line is wrapped around the drum and as it rotates.

Drum-shaped rope winch.

Wind vane (otherwise known as a weather vane, wind indicator or a wind sock) is a small device at the end of the mast whose arrow indicates where the wind is blowing from.

How to sail: A-Z of Yachting Terms

When learning how to sail have you ever wondered when you are on a yacht what some of those yachting terms mean, we have asked our RYA Training Centre pupils which ones confuse the most. Here are a selection, which includes the obvious to the more obscure!

A baft: A location on the boat but further to the rear of the boat. “The tiller is abaft the mast.”

A beam: The beam is the widest part of the boat. When another boat is abeam, it is at a right angle off the beam to either the starboard or port side of the boat you are on.

A ft: When on a boat you refer to the stern part of the boat as being aft or to the rear of the boat.

A head: A term used to describe the area in front of the boat you are on. “Look ahead.”

A ids to Navigation: This includes all external systems like channel markers, preferred route buoys, danger and safe water buoys, isolated danger and regulatory markers etc. that help determine a boats position or course, the presence of dangers or obstructions and the preferred route to navigate.

A midships: In the middle of the boat between the stern and the bow.

A pparent Wind: The apparent wind is a combination of the true wind and the wind caused by the boat travelling through the water. On an windex, the apparent wind will cause the windex to show wind direction just in front of the true wind.

A stern: A location off the boat and behind it.

B ulkhead – Refers to an often watertight, interior wall on the boat

Backing Wind: Refers to the wind shifting direction in a counter-clockwise direction. This usually means that bad weather is approaching.

Backstay: A wire running from the top of the mast to the stern of the boat. The backstay stops the mast from falling forward and also helps to control the degree of mast bend when tuning a boat.

Battens: Wood, fiberglass or plastic strips slid into pockets along the leech of the sail. Battens help to shape and strengthen the sail to increase overall performance.

Beam: The widest part of the boat.

Beam Reaching: One of the points of sail. You are ‘beam reaching’ when sailing directly sideways to the wind on either a port or starboard tack. Think of a clock face – if the wind is blowing from 12 o’clock, sailing at between 3 o’clock or 9 o’clock would be a beam reach.

Bearing Away: Turning away from the wind or turning downwind.

Beating: Sailing towards the wind by tacking back and forth across the wind.

Belayed: Secured, tied to, made fast to.

Bend On: To secure one thing to another. Tieing two lines together.

Bifurcation: A channel junction (two channels meeting) usually marked by a ‘bifurcation buoy’ indicating the perferred channel to follow.

Bight: A loop or bend in a line.

Bilge: The lowest inner part of a boats hull.

Bitter End: The utmost free end of a line. (The other end is referred to as the ‘Standing Line’).

Boat Wind: The wind created by the boat moving through the water. The true wind and the boat wind combine to create the apparent wind direction.

Boat Fall: Rigging used to raise or lower a ship’s boat.

Boat Painter: Rope tied to the front end of a boat used to either tow a boat or to secure it to a dock.

Bollard: Wooden or iron post on a pier to which the boat is secured.

Boom: The boom is the pole running aft from the mast to which (among other things) the foot of the mainsail is attached.

Bowline: A very strong and yet easy to untie knot that creates a loop in the end of a line.

Breastlines: Mooring lines that run from the bow and the stern at right angles to the dock to stop the boat from drifting out from the dock.

Broad Reach: One of the points of sail. Sailing downwind off to the port or starboard side. Think of a clock face – if the wind is blowing from 12 o’clock, sailing at between 4-5 o’clock or between 7-8 o’clock would be a broad reach.

By the Lee: Sailing downwind with the mainsail remaining on the same side of the boat that the wind is hitting. If you are sailing downwind on a port tack, typically the mainsail would be off the starboard side of the boat. When sailing ‘by the lee’, the mainsail in the same situation would remain on the port side of the boat out at a 90 degree angle to the boat.

C lew – The lower aft corner of a sail

Cabin: The below deck living quarters.

Cable: Measurement of distance equal to 0.1 nautical mile.

Cam cleat: A fitting through which a line is run through. The cam cleat consists of two cams that wedge against the line stopping it from being pulled out.

Cardinal Aids to Navigation: Buoys with indicate the location of hazards, safe water or deep water by reference to the four cardinal points of a compass (North, South, East, West).(See our section on buoys for a more complete explanation.)

Catboat: A boat with one mast flying no foresail (jib).

Cast Off: To release the lines allowing the boat to leave it’s mooring.

Chainplates: Very strong metal plates affixed to the hull to which the forestay, backstay and shrouds are attached.

Chart Datum: For navigational safety, depths on a chart are shown from a low-water surface or a low-water datum called chart datum. Chart datum is selected so that the water level will seldom fall below it and only rarely will there be less depth available than what is portrayed on the chart

Chock: a metal fitting, either oval or U-shaped, through which mooring lines are passed. Chocks help reduce abrasion saving the lines from excessive wear and tear.

Cleat: A small, metal deck fitting with horns used for securing lines (belaying).

Clew: The lower rear corner of a sail.

Close Reach: Point of sail – sailing against the wind at an angle somewhere between a Beam Reach and Close Hauled. Think of a clock face – if the wind is blowing from 12 o’clock, sailing at 2 o’clock or 10 o’clock would be a close reach.

Close Hauled: Point of sail – sailng as close to the wind (sharp angle to the wind) as possible without the sailings luffing (fluttering).

Cockpit: The open inset area from where the boat is steered.

Companionway: Stairs or ladder on a boat usually leading down to the cabin.

Cringles: Open metal rings inserted into the sail (also called grommets) used as reefing points for a sail but also found at the clew, head and tack of the sail to attach halyards, lines, outhauls etc.

Cunningham: A line used to adjust the forward edge of the mainsail. Usually runs from the tack of the sail to the front area of the boom.

Current: The horizontal flow of water. (Tide is the vertical flow of water.)

Cutter: A cutter has one mast but sails with two foresails.

D raft – This describes the depth of a boat measured from the deepest point to the waterline

Davit: A crane onboard that can be swung out over the side for hoisting or lowering boats.

Dead Reckoning: Navigational term – method used to plot the course already travelled by measuring speed and time to calculate distance.

Deep Six: A slang term meaning to discard something over the side of the boat.

Degree: A distance of measurement on a nautical chart. One degree equals 60 nautical miles. Each degree is broken down into 60 minute intervals. One minute of one degree equals 1 nautical mile.

Deviation: A ship’s magnetic compass reading can be affected by metal objects on the boat (electronic equipment etc). The difference between the correct magnetic reading and the ships compass magnetic reading is called deviation. Deviation will vary depending on the direction of the boat.

Dog: A metal fitting used to secure watertight doors, hatch covers and scuttles.

Downhaul: A line attached to the tack of the sail and used to pull down or tighten the mainsail to increase sale efficiency.

E ase: To let out or ‘ease off’ a line.

E nsign – The national flag of the boats home country

F Fairleads: A metal fitting through which lines are run to in order to change the direction of the lines while reducing friction on the lines.

Fairway: Sailing on inland waters, fairway means an open channel or being in midchannel.

Fast: To make fast. To secure (snugly tie) a line to something.

Fathoms: A unit of measurement. One fathon equals 6 feet.

Fenders: Cylindrical air filled plastic or rubber bumpers hung off the side of a boat or dock to prevent damage to both dock and boat.

Fetch: The distance over open water the wind has blown.

Faked: A line is faked by zig zagging it back and forth so that when it is used it will not tangle on itself.

Flaked:A sail is flaked when lowered. Flaking a sail is the process of folding the sail back and forth upon itself like the blades on a paper fan. Flaking a sail will help prolong the sail life.

Foot (Sail): The foot of a sail is the lower part of the sail. In the case of a mainsail, this is the part of the sail that runs along the boom.

F orepeak- The cabin most forward in the bow of the boat

Forestay: The forestay is a wire that runs from the top of the mast (or near the top of the mast) to the bow of the boat. The forestay supports the mast from falling backwards and is also used in shaping the bend in the mast for maximum efficiency. The luff (front) of the foresails (jib, genoa) are also generally attached to the forestay depending on the rigging system.

Forward: When on a boat, forward means towards the bow. “Move forward” – move towards the front of the boat.

Galley: The boat’s kitchen.

Genoa: The Genoa is a foresail that is larger than a jib. The clew (lower corner at the foot of the sail) extends aft of the mast unlike a jib.

Give-way Boat: Navigational rules – the boat not having the right-of-way. The Give-way boat must stay clear of the Stand-on boat. The Give-way boat must make it’s intentions known by making a decisive maneuver to alert the Stand-on boat.

Gooseneck: This is a metal fitting that attaches the boom to the mast.

G oosewinging – To sail downwind with the mainsail set on one side and the foresail on the other

Gybing: Sailing down wind and turning through the wind causing the sails to move from one side of the boat to the other.

Gybe ho: Term used by the helmsman to let his crew know that he has started to turn the boat into a gybe.

H alyard – A line which is used to raise things on a boat, so the main halyard line would be used to raise the mainsail

Halyards: Lines used to lower and raise sails.

Hanks: Clips found along the luff (front) of the foresail used to clip the sail onto the forestay (wire running from the bow to the top or near the top of the mast).

Hard over: Turning the wheel or pushing the tiller all the way over.

Head: Generally used to refer to the boat’s toilet. When talking about a sail, the Head is the top of the sail.

Head to Wind: The bow of the boat is pointed directly into the wind.

Heading up: Turning up more into the wind.

Heaving to: A way to, in effect, stall a sailboat by backing the jib, easing out the mainsail and turning the rudder hard into the wind. The forward wind pressure on the foresail wants to force the bow downwind. The rudder turned towards the wind wants to force the bow windward. These two counter effects balance each other causing the boat to hold it’s position with little movement. The mainsail is eased out all the way so that it does not catch any wind and therefore has no bearing on the boats postion.

Heeling: Leaning or heeling over caused by wind pressure on the sails.

Helm: The Helm is the steering mechanism of the boat (wheel or tiller). The person at the helm is called the helmsman.

Helms Alee: A term used by the helmsman to notify the crew that he has started to tack. Hypothermia: A dangerous condition where the body core temperature has been lowered causing extreme shivering, loss of co-ordination, in ability to make decisions and in extreme cases, loss of conciousness and even death.

I nlet – A recess, such as a cove or bay, along a coastline

In Irons: This occurs where the boat has been turned directly into the wind and has lost all forward momentum. Without forward momentum the boat loses it’s ability to steer.

J ackstay – A strong line, that can be made of wire, which runs fore and aft alongside the boat that can be used to attach your safety harness to.

Jacob’s ladder: A light ladder made of rope or chain with metal or wooden rungs used over the side or aloft.

Jib: The jib is a foresail (smaller than a genoa). The jib is about the same size as the triangular area between the forestay, mast and foredeck.

Jiffy reefing: This is a way to make the mainsail smaller by partially lowering it, tying or reefing the lower slack part of the sail onto the boom through gromets (holes in the sail) called reefing points. This is done in high wind conditions to power down the sail.

Jury rig: Makeshift – adapting parts and materials for a use not specifically designed for in order to get by until proper parts or repairs can be obtained.

K etch – A sailboat with 2 masts

Kedging: A method used to free a grounded boat by dropping it’s anchor in deeper water and then pulling on the anchor rode to attempt to free the boat.

Keel: The large heavily weighted fin like structure secured to the bottom of the boat. The keel helps to keep the boat upright and also reduces leeway (side slipping across the wind).

Ketch: A two masted boat. The second and smaller mast (mizzen) is positioned just forward of the rudder post.

Knot: Rate of speed. On land it is miles per hour, on the water it is knots (nautical miles) per hours. One knot equals 1.15 land miles – so one knot is just a bit faster than one mph.

L eeway – The sideways movement of a boat caused by wind and currents

Lateral Aids to Navigation: channel buoys (Red & Green), isolated danger buoys (Black & Red), safe water ahead (Red & White), regulatory buoys (Yellow), bifurcation buoys (Black & Yellow) plus channel identification markers and navigation markers are all considered Laterial Aids to Navigation.

Lazarette: A storage compartment, usually under the seats of the cockpit.

Lee Helm: Also called Weather Helm, this is the tendancy of the boat to turn into the wind once it has heeled over at a sharp angle.

Lee Shore: Feared by most sailors, this is the downwind shore from the boat.

Leech: The rear edge of the foresail or the mainsail running from the head (top) to the clew (rear corner) of the sail.

Leeward: Downwind.

Leeway: When a boat sails across the wind, the force of the wind causes the boat to slip sideways. This drifting or sideway motion is known as Leeway.

Lifelines: The lines running around the outside of the deck creating a railing. The lines are attached to stanchions (upright metal posts).

Luff: The forward edge of a sail running from head to tack (front corner of the sail).

Luffing: A sail is luffing when it starts to flutter in the wind. The term Luff is also used to describe the same situation. “The sail is starting to luff.”

Luff Up: To turn into the wind to cause the sails to start luffing.

M ultihull – Any boat that has more than one hull, such as a catamaran.

Made fast: Secured to.

Mast: The upright pole supported by the shrouds, forestay and backstay to which the sails are attached.

Masthead fly: A windvane attached to the top of the mast to show which direction was wind is coming from.

Monkey fist: A type of knot, heavy in nature and tied to the end of the rope. The weighted knot makes it easier to throw the rope a farther distance.

Mooring ball: An anchored ball to which you can secure your boat. Safer alternative to anchoring provided the mooring ball and lines are in good condition.

Mooring lines: Lines used to secure a boat to a dock or mooring ball.

MSD: Marine sanitation device (toilet).

N eap tide – When during the four week tidal cycle, the tide rises and drops the least.

Nautical mile (NM): International standard for measuring distance on water. One nautical mile equals one minute of latitude. (One nautical mile equals 1.15 land miles.)

O uthaul – This is a line used to tension the foot of the sail, to better control the curvature of the sail

P ulpit – A sturdy rail around the deck on the bow, normally surrounding the forestay

Pad eye: A metal eye (ring) through which lines can be passed in order to stop chaffing.

Painter: The bow line of a dinghy.

P-effect (Prop Walk): When a boat is in a standstill position and put into forward or reverse, the resistance of the boat to move and the motion of the propeller creates a paddlewheel effect pulling the stern of the boat to either port or starboard side depending on the spin of the propeller. This paddlewheel effect is known as P-effect or Prop Walk. P-effect is especially noticable in reverse where there is greater boat resistance to move backwards thus making it easier for the prop to pull the boat sideways.

PFD: Personal Floatation Device – life jacket.

Pintle and gudgeon: The pintle and the gudgeon together form a swinging hinge usually associated with the installation of the rudder on smaller tiller steered boats. The pintle has pins that fit into the holes on the gudgeon thus creating a hinge like fitting.

Points of sail: A reference for the direction the boat is travelling in relation to the wind. (in irons, close hauled, close reach, beam reach, broad reach, running)

Port: When on a boat and facing forward, the left hand side of the boat.

Port tack: Sailing across the wind so that the wind hits the port (left) side of the boat first.

Pulpit: Located at the bow of the boat, this area is enclosed by a metal railing.

Pushpit: Located at the stern of the boat and like the pulpit, this area is enclosed by a metal railing.

Q uadrant – This is a device connected to the rudder that the steering cables attach to

R egatta – Boat races

S hroud – The wires at the side that hold the mast up

Schooner: A sailboat that has two masts both the same height or on some schooners, the aft mast is higher than the fore mast.

Scope: Expressed in terms of a ratio, it is the length of the anchor rode let out compared to height above the sea bed. Height is measured not from the water line but from the top of the deck to the sea bed. A safe anchoring ratio is 1:7 which translates to 7 feet of anchor rode for every foot of height. Many sailors incorrectly assume that height means water depth and therefore find themselves dragging the anchor for lack of proper scope.

Seaworthy: A boat that is fit to be sailed at sea.

Self-bailing cockpit: A cockpit that allows water to drain automatically from the cockpit to the outside of the boat.

Shackles: Metal fittings (often U shaped) that open and close with a pin across the top of the ‘U’. Lines and halyards often use shackles. The mainsail halyard is secured to the head of the mainsail with the use of a shackle.

Sheave: A roller/wheel to guide a line or wire.

Sheets: Lines that are used to adjust sails by either pulling them in or by letting them out.

Shrouds: Also called sidestays, shrouds are the metal wires found on both sides of the mast running from the deck to the top or near top of the mast. The shrouds support the mast by providing lateral support.

Slack water: The period between the flood (tidal water moving in) and the ebb (tidal water moving out) where the water has in effect stalled – little or no movement.

Slides: The groove in the mast to which the luff (front side) of the mainsail is inserted. The slides hold the sail tight against the mast and allows the sail to be easily raised or lowered.

Sloop: a sailboat that has one mast and sails with the mainsail and one foresail.

Soundings: Water depths.

Spar: A spar can refer to any of the following: mast, boom or a pole.

Spinnaker: A large balloon-like foresail used for sailing downwind (running or broad reach).

Spinnaker pole: The spinnaker pole is boom-like in nature, but smaller and lighter, and attaches to fore part of the mast a few feet up from the deck. The other end of the spinnaker pole attaches to the leeward (down wind) base of the spinnaker.

Spreaders: Bars extending sideways from the mast (gives the mast a cross-like appearance). The spreaders hold out the shrouds so that they do not interfer with the rigging.

Springlines: Springlines are used to secure a boat to a dock and stop the boat from moving forward or backwards. The aft springline runs from a point on the boat near the bow to a point aft on the dock. The forward springline runs from a point on the boat near the stern to a point forward on the dock.

Squall: A sudden isolated storm associated with potentially high wind gusts.

Stanchions: Upright metal posts running around the outside of the deck supporting the lifelines.

Stand: This refers to the short period of time where the tide is neither rising or falling. (At a stand still.)

Standing rigging: Standing rigging includes the forestay, backstay and the shrouds. Unlike the ‘running rigging’, the standing rigging is generally only adjusted when the boat is not underway.

Stand-on boat: The boat that must retain her current course and rate of speed in order to avoid a potential collision with an approaching give-way boat.

Starboard: As you face towards the bow on a boat, starboard is the right hand side of the boat.

Starboard tack: Sailing across the wind with the wind hitting the starboard (right) side of the boat first.

Steerage: The ability of the boat to be steered. In order for a rudder to be effective in steering a boat, there must be boat movement. A boat not moving cannot be steered.

Stern: The most aft part of a boat (the very back of the boat).

Storm jib: Same as a jib but not as big. The smaller sail is used in high wind conditions.

T ender – A small boat or dinghy used to ferry crew between the boat and shore

Tack: The front lower corner of a sail. Also means to sail back and forth across the wind in either a port or starboard tack.

Tacking: Also called “Coming About”. Tacking is when the bow of the boat is turned through the wind onto the opposite tack.

Tail: The bitter end of a sheet tailing out from a winch.

Tang: A metal fitting used to affix the stays to the mast.

Telltails: (Also called Ticklers) These are small strings (wool, plastic) attached to both sides of the luff of the sail. When the telltails on both sides of the sail are blowing straight back, this indicates that the sail has been properly trimmed.

Through hulls: Through hulls are holes that go through the boat. Each through hull will have a shuttle cock (value) to stop the flow of water. An example of a through hull would be the head (bathroom). A through hull value is opened so that water from outside the boat can be pumped into the MSD (toilet). The value is closed and the toilet pumped empty into a holding tank.

Tide: The vertical rise and fall the oceans.

Tide rips: This is an area of rough water where the wind is blowing across the water in the opposite direction from which strong tidal current is flowing.

Tiller: In boats that are not steered by a wheel, a tiller (long handle) is attached to the top of the rudder in order to facilitate steering.

Toe rail: A small metal railing running around the outside of the deck used to support your feet.

Topping lift: A line running from the top of the mast to the end of the boom. The topping lift supports the boom when the sail has been lowered.

Topside: The portion of the hull above the water line.

Transom: The flat area across the stern of the boat.

Trim: To trim or adjust the sail to make it more effective against the wind.

True wind: The actual wind felt wind the boat is not moving.

Turnbuckles: Adjustable fittings usually attached at the end of shrouds and stays. Turning the turnbuckle one way or the other tightens or loosens the wire.

U nfurl – To unroll a sail

Upstream: Moving from seaward into harbor, moving with the flood of the tide, moving up river toward the headwaters.

V ane – A wind direction indicator

Veering: A wind shift in the clockwise direction usually indicating that good weather is approaching.

W inch – A mechanical device for pulling in a line

Wake: The waves created behind a boat as a result of the boat moving through the water.

Way: Movement of the boat.

Weather helm: The tendancy of the boat to turn up wind after heeling (leaning over).

Wheel: Controls the rudder. Taking control of the wheel is taking the helm.

Winch: Provides a mechanical advantage. Used to raise the sails, tighten the sheets and other lines.

Windward: Towards the wind.

Wing to wing: Running (sail directly downwind) with the mainsail out one side of the boat and the foresail out the other side of the boat.

X marks the spot on the treasure map!

Y awing – The side to side movement of a boat on an uneven course

Yawl: A sailboat that has two masts. The aft mast (mizzen) is shorter than the foremast. The mizzen mast is located aft the rudder post. (On a Ketch, the mizzen mast is located fore of the rudder post – this is the distinquishing factor between the two.)

Z ephyr – A very light westerly wind

Sailing Terms: A Complete Guide

Last Updated by

June 15, 2022

Learning sailing terms when you first get into boating can be a daunting task.

Some sailing terms are logical, like 'fore' means forward or front of the boat, while others might as well be in a different language. Athwartship, for example. Nothing in our daily lexicon gives any clues as to what that might mean. Like it or not, it's time to dust off the old noodle and get to memorizing some new vocab words!

Knowing the difference between a clew and a tack, a luff and a leech, will help you communicate with your sail maker regarding which part of your sail needs resewn. If you need to have your rigging adjusted, you must know the difference between your shrouds and your stays, your standing rigging vs. your running rigging.

By educating yourself in the correct names of all parts of your sailboat, you can avoid situations in which you may need to use terms such as ‘thingy’ or ‘that round part at the end of that thing’. While even the most seasoned sailor occasionally troops over the vernacular, it is always beneficial to have as wide a nautical vocabulary as possible. Many in the sailing community get by without knowing the entire sailing dictionary, but if you’re interested in avoiding vocabulary embarrassment, check out the list I’ve compiled of sailing terms that every sailor ought to know.

I’ve been sailing on and off throughout my life and I know from experience that it is incredibly helpful to know the correct terms for each part of your sails, rigging, and boat.

Sailors are among the kindest, most helpful people you’ll ever meet. But, if you’re looking for help on why you’re not getting the most speed out of your mainsail and you know don’t know the correct terms for each part of the sail, it may be hard to get advice from you fellow sailor on why ‘the back of the mainsail is flappy’. They would be more likely to give useful advice if you’re able to tell them that you’re struggling to keep wind in the roach of your mainsail. Check out my list of sailing terms and see if a few don’t stick. I’ve done my best to include pictures when possible.

Table of contents

Sailing Terms

Abeam : When an object, craft or island is abeam your vessel, that means that it is off the side of your boat. It is 90 degrees from the centerline of your boat.

Abaft : Toward the stern. “Honey, have you seen my boat shoes?” “They’re abaft the navigation table!” This is the opposite of forward.

Aft : In the stern of the boat. For example, the back cabin is referred to as the aft cabin.

Apparent wind : The wind direction and speed which the crew observes to be blowing in combination with the true wind. This is often different from the true wind direction and speed due to the boat's motion.

Astern : The area behind the boat. If you go astern, you are going in reverse.

Athwartship : Directionally perpendicular to the centerline of the boat.

Backing (a sail) : Forcing the sail to take wind into its opposite side by pulling the sail to the opposite side of the boat.

Backstay : The wire that runs from the back of the boat to the mast head. This prevents the mast from falling forward.

Bailer : Any scoop-like container that is used to remove water from within a vessel’s hull.

Ballast : Weight which adds stability to the vessel. The weight usually is composed of lead or iron and placed low in the boat's hull, such as within the keel.

Batten : a thin, flexible strip (often fiberglass) that is inserted into the main sail to help it stay open to the wind. The batten runs from the back edge of the sail (leech) toward the front edge (luff).

Beam : The width of the vessel at its widest point.

Beam reach : Sailing with the wind blowing perpendicular to the direction the boat is traveling.

Bearing off or Bearing away : Steering the boat away from the direction in which the wind is blowing.

Bend : a knot which connects two ropes.

Berth : A slip, a mooring, or a bed within the boat.

Bight : A bend or loop in a rope. When a rope forms a bight, it has changed direction 180 degrees.

Bilge : The lowest area within a boats hull. This area collects water which is then pumped overboard by a bilge pump.

Bimini : The covering over the cockpit. Usually constructed from a stainless steel frame covered with canvas or fiberglass. It provides protection from sun and rain, but not wind.

Binnacle : The pedestal centrally located in the cockpit that generally holds the steering wheel and navigational instruments.

Block : A pulley.

Boom : This pole runs perpendicular to the mast and holds the bottom of the mainsail in place. Its position is adjustable side to side as needed for the wind direction.

Boom vang : A tackle which ensures that the boom does not lift upward from wind pressure in the mainsail.

Boot Top or Boot Stripe : The stripe of tape or paint between the boat's underwater (bottom) paint and it’s above water (topside) paint.

Bow : Front end of the boat

Bowsprit : The forward most protruding pole or platform which some boats possess. This spar allows for the sails and rigging to be attached further forward.

Broach : When a boat sailing downwind accidentally ends up sideways to the waves and heels over dangerously. This can be caused by large seas or poor steering.

Broad reach : Sailing with the wind coming off your stern quarter. If you’re standing at the helm facing the bow, the wind is blowing halfway between the side and the back of the boat.

Bulkhead : The walls in a boat which run athwartship, or perpendicular to the centerline of the vessel.

Capsize : When a vessel tips over past 90 degrees.

Catamaran : A vessel with two hulls.

Centerboard : A retractable keel which helps the sailboat maintain course and stability underway. When raised, the vessel is able to enter shallow waters.

Centerline : An imaginary line that runs from the center of the bow to the center of the stern.

Chainplate : A metal plate that is secured to the boat's hull to which wires supporting the mast are attached. The chainplates may be exterior or interior, visible or hidden.

Chandlery : A store that sells boat supplies and parts.

Cleats : The wooden or metal piece to which ropes are secured.

Chock : A fitting that a line passes through to change direction without chafing.

Clew : The lower back corner of a sail. This is where the foot and leech of the sail meet.

Close-hauled : Sailing as close to the direction the wind is coming from as possible with the sails pulled in tight. (See Points of Sail for infographic.)

Close Reach : Sailing between close hauled and beam reach. (See Points of Sail for infographic.)

Coamings : The lip around a hatch or window which stops water from entering. Also the raised area around the cockpit to keep out water.

Cockpit : The area from which steering occurs. This can be in the center of the boat or in the back of the boat.

Companionway : The doorway into the cabin.

Cotter pin : a bendable metal pin which is inserted into a metal rod then bent to lock it in place.

Daybeacons : Markers for navigation which are on posts. These are red or green.

Dead run : Sailing with the wind coming from directly behind the boat. Sails are fully out to catch the wind.

Dead reckoning : Determining a vessel's position by knowing the direction and speed traveled.

Dinghy : A small boat which is used to travel to shore from the main vessel. This can be propelled oars or a motor.

Dodger : The structure at the front of the cockpit which protects the cockpit and companionway from wind and spray. This is generally made of stainless steel frame covered with canvas and plastic windows. It can also be a solid structure with solid windows.

Dismasting : When the mast breaks off the boat. This can occur due to rigging failure or structural failure of the mast.

Displacement : The weight of the water that would otherwise be in the place of the boats hull.

Drogue : A sea anchor which is deployed to help control the drift of a vessel. It can be constructed like a parachute, bucket, or even a rope dragging behind the boat.

Ebb tide : After high tide when the water is receding towards low tide.

EPIRB : Stands for Emergency Position Indicating Radio Beacon. This device transmits a distress signal to emergency services and notifies them of a vessel's location.

Heave to : A method of controlling a boat’s position to the waves and limiting headway by backwinding the forward sail and keeping the rudder hard over into the wind.

Heel : The tilt that occurs to a boat's hull when the sails are filled with wind.

In-Irons : When a sailboat is bow into the wind with sails flapping. No steerage is possible as the vessel has no forward motion. (See Points of Sail for infographic.)

Jackline or Jackstay : Lines that are run from the bow to the stern. To these safety lines, sailors attach a lanyard connected to their harness so that they may work on deck without fear of being swept overboard in rough seas.

Jib : A triangular forward sail.

Jib sheets : Lines used to control the jib.

Jibing : Pronounced with a long i sound. Steering the boat from one downwind direction to another downwind direction by turning the stern of the boat through the wind. This will cause the sails to move across the boat to the other side, i.e. from port to starboard.

Kedge anchor : A small, lighter second anchor.

Keel : The bottom most part of a boat's structure. This part provides ballast and stability.

Ketch : A sailboat with two masts. The forward mast is the taller mast.

Knot : Regarding speed, one knot is equal to one nautical mile per hour.

Lazyjacks : Light lines that run from the boom to the mast and help contain the mainsail while it’s being lowered to the boom.

Leech : The back edge of a sail. If the sail is square, then this term refers to the outside edges of the sail.

Lee shore : The shore onto which the wind is blowing. On an island, the side of the island facing into the wind is the lee shore.

Leeward : The direction to which the wind is blowing. If the wind is coming from the north, then south is leeward.

Luff : The forward edge of the sail.

Lying a-hull : When a vessel is drifting with all of it’s sails down.

Multihull : A vessel with more than one hull such as a catamaran or trimaran.

No-sail zone : This is an area 45 degrees to either side of directly into the wind. It is not possible for a boat to sail in this zone as the sails cannot fill with wind. Tacking is necessary. (See Points of Sail for infographic.)

On the hard : When a vessel is out of the water and being stored on land.

Painter : The line which secures the bow of a dinghy to the main boat.

Pan Pan : Pronounced pon-pon. This is an urgent distress radio call which is used when a vessel needs assistance. It is one step below Mayday.

Rigging : All the wires and ropes used to hold the mast in place and adjust the sails.

Roach : The outer back edge area of the mainsail. If you were to draw a diagonal line from the head of the sail to the clew (back corner), the roach would be outside this diagonal line.

Roller furling : A system which rolls the sail up when not in use. The sail is stored on the roller either at the mast or boom for the mainsail, and at the forestay for the jib or genoa.

Rudder : Steering fin at the back of the boat. Controlled by a steering wheel or tiller from the cockpit.

Sloop : A single masted sailboat with a mainsail and a foresail.

Slugs : Fittings on the front edge (luff) of the mainsail that slide into the mast track for hoisting the sail.

Spinnaker : A large, light, often colorful sail that is used off the bow of the boat for sailing downwind (running).

Splice : Connecting two lines together by weaving their strands together.

Spreaders : The horizontal arms extending out from the sides of the mast.

Spring line : Dock lines positioned from the bow to a midship point on the dock or from the stern to a midship point on the dock. This line configuration helps decrease forward and backward motion of the boat while docked.

Tender : Small boat used to transport from shore to the main boat.

Tiller : A bar which controls the rudder and is used to steer the boat from the cockpit. It is used in place of a steering wheel.

Toe rail : The raised lip around the edge of the deck. This can be constructed of wood, fiberglass, or aluminum. It helps prevent items from rolling overboard.

Topping lift : A wire or rope which runs from the back end of the boom to the mast top. This line controls the height of the boom.

Trysail : A small, strong storm sail that is used in place of the mainsail in high winds.

Yacht Terms: A Comprehensive Guide

by Emma Sullivan | Aug 3, 2023 | Sailboat Lifestyle

Short answer yacht terms:

Yacht terms refer to specialized vocabulary used in the sailing and boating industry. These terms include jargon related to different parts of a yacht, such as masts, rigging, hull, and sails. Familiarity with these terms is important for effective communication and understanding within the yachting community.

What Are Yacht Terms?: A Comprehensive Guide

Welcome to our comprehensive guide on yacht terms! Whether you’re a seasoned sailor or new to the world of yachting, understanding these terms is crucial for smooth and efficient communication onboard. From bow to stern, we’ll explore the most essential terms that any yacht enthusiast should know.

1. Bow: Let’s start at the front of the yacht. The bow refers to the forward section or front end of the vessel. It’s important for everyone to know and recognize this term as it sets the directional reference point when giving instructions or describing positions on board.

2. Stern: In contrast to the bow, the stern is what we call the rear section of a yacht. Much like knowing your front from your back, recognizing and using “stern” correctly ensures clear communication when maneuvering around waterways or docking .

3. Port: When standing aboard a yacht and facing forward (towards the bow), port refers to the left-hand side of the vessel. An easy way to remember this could be “Port has four letters, just like ‘left.'”

4. Starboard: Similarly, starboard is used in reference to the right-hand side while facing forward on a yacht. An amusing way some people remember it is that both starboard and right have more letters than their counterparts (port and left).

5. Helm: The helm can refer to two things – firstly, it represents both steering mechanisms found at either end of an axis connected by cables or hydraulics within a modern-day cockpit made up of wheels or levers; secondly, it encompasses all control systems used by crew members responsible for operating and navigating a yacht safely .

6.Navigation lights: These are lights mounted on different parts of a boat that indicate its position during nighttime operations in accordance with international regulations established by organizations such as International Maritime Organization (IMO) or U.S Coast Guard (USCG). They include sidelights (red/green), masthead light (white), stern light (white), and anchor light (white) for safe navigation .

7. Draft: The draft of a yacht refers to the vertical distance between the waterline and the deepest part of the hull below it. It’s important to be aware of a yacht’s draft as it determines where it can safely navigate, particularly in shallow waters or near reefs.

8. Anchor: This heavy piece of equipment is used to secure a yacht in place by digging into the seabed below. Dropping anchor allows vessels to remain stationary when not underway or during leisurely stops along a voyage.

9. Galley: The galley is essentially the kitchen area on board a yacht where meals are prepared. While often compact and efficient, it can still accommodate gourmet cooking experiences thanks to innovative design solutions specifically created for yachts.

10. Captain: The captain, also known as the skipper or master, is responsible for overall command and management of the yacht. They oversee all aspects of navigation, safety, crew coordination, guest experience, and more while ensuring a smooth journey at sea .

Now that you’re armed with this comprehensive guide on key yacht terms, you’ll be able to navigate conversations onboard like a pro! These terms provide clarity and understanding among crew members, making every sailing experience enjoyable and safe. So go ahead – embrace your inner sailor and set sail with confidence!

Understanding Yacht Terminology: Step-by-Step Explanation

Embarking on a yacht adventure is an experience that promises luxurious comfort, breathtaking views, and a great deal of excitement. But before you set sail and immerse yourself in the world of yachting, it’s essential to have a firm grasp on some yacht terminology. This knowledge will not only allow you to navigate conversations with ease but also enhance your overall enjoyment onboard. So, let’s dive into the depths of yacht terminology and unravel its intricacies step by step.

1. Hull: Let’s start at the very foundation of any yacht – the hull. The hull is the main body of the vessel and serves as its structural framework. Made from various materials like fiberglass or aluminum, it keeps everything together while gliding gracefully through the water. Think of it as the exoskeleton that gives a yacht its robustness and stability.

2. Bow and Stern: Picture yourself standing at one end of the boat looking forward – that’s the bow. Now imagine turning around to face aft – that’s where you find the stern. Remembering these two terms is crucial when receiving directions or discussing different areas on board.

3. Port and Starboard: To avoid any confusion regarding which direction to go while navigating a yacht, it’s important to understand port and starboard – essentially left and right respectively when facing forward (or bow). These directional references remain constant regardless of whether you’re staring at a majestic sunset or being mesmerized by marine life on either side.

4. Aft & Forward: As mentioned earlier, aft refers to the rear part of a vessel while forward means towards the front or bow end. Simple enough? This terminology effortlessly guides your understanding when moving from one point to another within the confines of your magnificent floating abode.

5. Draft: Now let’s delve into a term associated with how deep your vessel extends below water level – draft! It’s important to consider the draft when embarking on a journey in waters with varying depths . Knowing this measurement ensures a safe passage without any unexpected surprises.

6. LOA: Ah, the beauty of abbreviations! In yacht terminology, LOA stands for “Length Overall.” This measurement represents the entire length of the yacht from its foremost point to its aftmost point. Understanding LOA helps you comprehend size comparisons and can be an essential factor when considering marina berths or access through bridges.

7. Beam: As important as length, beam refers to the width of your yacht at its widest point. Knowledge of beam helps determine how much space is available, especially in tight quarters or areas that require precise maneuvering skills.

8. Superstructure: Now we move onto the part that satiates our aesthetic cravings – the superstructure! This refers to everything built on top of and above the main hull, such as cabins, decks, and helm stations. The superstructure gives yachts their gorgeous silhouette and defines their character.

9. Flybridge: Speaking of superstructures, let us introduce you to one of the most coveted spots on a yacht – the flybridge. Situated above the main deck and affording breathtaking panoramic views, it’s an outdoor sanctuary where one can relax, dine, or simply soak up the sun in style.

10. Galley: Behind every tantalizing meal served onboard is a hidden treasure called galley – essentially a fancy word for kitchen! If gastronomy is your passion or you simply appreciate culinary delights prepared by talented chefs on board, understanding where all the magic happens is vital.

By arming yourself with these key yacht terminologies, your journey into yachting will undoubtedly be smoother and more enjoyable than ever before. Now all that’s left is hoisting those sails (or turning on those engines) and setting sail toward adventure like a true seafaring professional!

Exploring the Vast World of Yacht Terminology and its Significance

Yachting is a world that’s synonymous with elegance, luxury, and adventure. It’s a lifestyle that allows individuals to navigate the open seas while indulging in utmost comfort and sophistication. However, behind this glamorous facade lies a complex vocabulary unique to the yachting community – yacht terminology.

Pristine decks, powerful engines, sleek hulls – these are just some of the elements that make up a yacht. But have you ever wondered what those terms like “bow,” “stern,” or “keel” mean? Understanding yacht terminology is not only essential for effective communication among crew members but also adds depth and knowledge to your yachting experience.

Let’s embark on an exciting journey into the vast world of yacht terminology, uncovering its significance along the way!

1. Bow and Stern: The Face and Tail of a Yacht When you step onto a yacht, it’s important to know where you’re going. The bow refers to the front part of the vessel – often beautifully designed with sweeping lines – which slices through waves as it moves forward. On the other hand, the stern is located at the back end of the boat, where all actions seem to converge.

Understanding these basic directions enables you to navigate and communicate effectively onboard while allowing you to appreciate every facet of your floating sanctuary.

2. Keel: A Yacht’s Stabilizing Backbone While not as commonly known as bow or stern, acknowledging what lies beneath – metaphorically speaking – is crucial. The keel runs along the bottom centerline of a yacht from bow to stern beneath its watery surface domain.

The primary purpose of this vital component is stability; it counters sideways forces exerted by wind or waves while providing lateral resistance when sailing against them. Treading water without proper knowledge could leave even seasoned sailors feeling adrift amidst these unseen forces.

3. Beam: The Width that Defines Spatial Comfort Ever wondered how spacious a particular yacht might be? Enter beam, one of the most important dimensions to consider. This term refers to the widest part of the yacht , measuring from one side to another along its hull.

A wider beam generally translates to more interior space, as it provides room for luxurious cabins, lounges, and other amenities essential for an opulent on-board experience. Knowing this allows you to marvel at broad-beamed yachts while appreciating their ability to provide ample comfort in even the finest dining areas or entertainment spaces.

4. Flybridge: The Ultimate Vantage Point If a yacht is a kingdom upon waves, then the flybridge is its elevated throne room. Situated above the main deck or enclosed bridge and often offering panoramic views of surrounding waters, this area symbolizes luxury like no other.

Commanding this position enveloped in luxurious amenities – including seating areas and possibly even a bar – heightens not only your perspective but also your status as ruler of your aquatic realm. Understanding flybridge terminology opens doors to exclusive opportunities unique to yachting enthusiasts who seek the ultimate vantage point.

5. Superstructure: The Architectural Marvel Above Deck Step beyond mere surface-level appreciation and delve into what makes a yacht truly magnificent – its superstructure! This nautical architecture refers to any structure built above the vessel’s hull. From elegant signal masts and stunning sun decks to striking helm stations and remarkable sky lounges – these elements contribute significantly to a yacht’s allure.

By acquainting yourself with various superstructures’ terminology, you gain insight into manifold possibilities for delightful moments spent basking under the sun or savouring breathtaking views amid your floating oasis.

In Conclusion Yacht terminology serves not only as a means of effective communication but also as a gateway enabling us to fully appreciate every aspect of our oceanic journeys. From understanding the directional language of bow and stern to embracing the architectural wonders of a yacht’s superstructure, delving into this vast world enhances our yachting experience .

So, next time you step aboard a majestic yacht, armed with your newfound knowledge and a dash of that witty nautical charm, engage fellow enthusiasts with conversations that celebrate both elegance and erudition. Exploring the realm of yacht terminology is an adventure you’ll cherish as it elevates your yachting journey from ordinary to extraordinary!

Mastering Yacht Terms: Essential Knowledge for Novice Sailors

Embarking on a sailing adventure can be an exhilarating experience, filled with the thrill of the open sea and the freedom to explore far-off destinations. However, for novice sailors, understanding the plethora of yacht terms can seem like navigating through uncharted waters. To help you become a seasoned sailor in no time, we’ve compiled this comprehensive guide to mastering yacht terms – essential knowledge that will make you feel like an expert on deck.

1. Bow and Stern: Let’s start with the basics. The bow refers to the front part or forward end of the yacht , while the stern is the rear or aft end. Knowing these terms is crucial for understanding directions when maneuvering your vessel.

2. Port and Starboard: The port side of a yacht is its left side when facing forward, distinguished by a red navigation light at night. Conversely, starboard refers to the right side, marked by a green navigation light . Remembering these terms will ensure smooth communication between crew members during maneuvers .

3. Helm: This term may remind you of a ship’s steering wheel in movies – and you’re not far off! The helm refers to both the actual wheel used to steer and control direction and its surrounding area where helmsman (or helmswoman) stands or sits while operating it.

4. Sailing into Windward vs Leeward: When sailing into windward, you are heading against or into the wind. This requires skillful maneuvering and strategic use of sails to propel forward effectively. In contrast, leeward refers to sailing downwind or in the same direction as the wind, resulting in smoother navigation but less challenging conditions.

5. Tacking and Jibing: These two maneuvers are essential techniques for changing your boat ‘s direction relative to the wind:

– Tacking involves turning your bow through head-to-wind by bringing it to the opposite side. This maneuver helps you sail into windward and is accompanied by shifting sails accordingly.

– Jibing, on the other hand, involves turning the boat away from the wind so that it comes from behind before adjusting your sails. This maneuver allows for a change in direction while sailing downwind.

6. Sheets: No, we’re not talking about bedding! In yacht terminology, sheets refer to ropes or lines used to control and adjust sails . The main sheet controls the mainsail (the large sail near the back) while jib sheets handle adjustments for the jib (a smaller triangular sail at the front).

7. Halyards: These are another set of ropes or lines used to raise or lower sails . A halyard typically runs through a pulley system attached to a mast or spar, allowing easy adjustment of sail positioning .

8. Winch: To use brute force when handling lines becomes challenging, enter the winch! A winch is a mechanical device typically operated by turning its drum in one direction using handles known as winch handles. It assists sailors in adjusting tension on lines swiftly and efficiently.

9. Cleats: Don’t let this term deceive you; it has nothing to do with your dentist! Cleats are metal or wooden devices found along yacht decks used for securing lines temporarily by looping them around these cleverly designed fittings.

10. Fenders: When docking at marinas or coming alongside other vessels, fenders become your best friends! Fenders act as cushions between your yacht’s hull and any solid surface, preventing damage and adding an additional layer of protection during mooring.

As a novice sailor armed with this newfound knowledge of essential yacht terms, you’ll feel more confident navigating both calm waters and challenging conditions like a true seafarer. So hoist those sails high, embrace adventure on deck, and remember – mastering these terms will unlock a world of possibilities on the open sea !

Deep Dive into Yacht Terminology: How to Navigate the Seas of Jargon

Ahoy, fellow seafarers! Whether you’re an avid sailor or simply enjoy basking in the luxury and elegance of a yacht, understanding the intricate world of yacht terminology is essential for navigating these opulent vessels. With a bewildering array of terms and phrases that can leave even the experienced mariners scratching their heads, it’s time to embark on a voyage into the deep sea of yacht jargon.

1. Bow vs Stern: Let’s start with the basics – bow and stern. The bow refers to the front or forward part of the yacht , while the stern represents its rear or aft section. Understanding these terms is crucial for maneuvering your way around docks and moorings with finesse.

2. Port vs Starboard: When someone tells you to head portside or starboard, don’t panic – they’re simply referring to your left (port) or right (starboard) side when facing forward. Portside will always be where the red navigation light resides, while starboard displays a green light .

3. Draft: Imagine you’re navigating shallow waters – knowing your yacht’s draft becomes critical. The draft refers to how far below the waterline your vessel extends, enabling you to determine whether certain destinations are accessible based on their depth.

4. LOA: Don’t be puzzled by LOA; instead, embrace it as your guiding light in determining total length – “Length Overall.” This term encompasses every inch from stern to bow inclusive of any additional extensions like platforms or swim decks.

5. Beam: Speaking of measurements, let us shed some light on beam – a term representing the widest point across your elegant vessel’s hull. It gives insight into how spacious and stable your yacht is likely to be.

6. Knots: Ever wondered why we measure speed in knots instead of good old miles per hour? Well, a knot is actually one nautical mile per hour. Considered the preferred unit in seafaring, it pays homage to the days of yore when sailors measured distance using knots on a rope .

7. Bollard: Next time you’re at a marina, take note of those sturdy posts that hold your yacht safely in place – those are bollards. These robust fixtures allow you to tie up your vessel securely and ensure it remains steadfast against any turbulent waters.

8. Foredeck vs Aft Deck: As you navigate the yacht like a seasoned sailor, distinguishing between the foredeck and aft deck is crucial. The foredeck refers to the forward portion, while the aft deck encompasses the rear section of your luxurious floating abode.

9. Galley: Your gastronomic adventures aboard require familiarity with this term – galley represents the kitchen area on a yacht . Just as skilled chefs would helm their domain in prestigious restaurants, navigating this culinary haven demands mastery.

10. Flotsam and Jetsam: No yacht journey would be complete without knowing these peculiar terms – flotsam and jetsam. Flotsam refers to wreckage or debris floating freely on water, while jetsam denotes items intentionally thrown overboard from a ship. Treasure hunters beware!

Boating Terms & Terminology

A glossary of yachting lingo.

Whether you’ve got a solid pair of sea legs or are brand new to the boating life, you probably know that yachting and boating comes with its own language.

Boating terms go back centuries and a lot of sailing vocabulary has been adopted as commonly used idioms in our everyday life. Many of us use them as second nature without even realizing their true origins. Just for fun, we’ve matched up a few of the most popular boating phrases with their everyday definition and use.

Expand your yachting vocabulary and have fun impressing your landlubber friends with your newfound knowledge. You’re about to get to know the meanings of phrases like “Anchors aweigh!”, “Move to the cathead” and “Crank the windlass.”

Parts of a Boat

Basics of Marine Navigation

List of Boating Terminology  

Abreast- boats sailing side by side at the same speed and position.

Everyday Use: we often use the term “abreast” to mean stay informed or updated. “Please keep me abreast of any changes in the plan.”

Aft- towards the stern (back) of the boat.

Belay- secure a line by winding on a cleat or pin.

Everyday Use: When all other possibilities are exhausted and someone reaches the very end. “They fought to the bitter end”

Cast Off – to remove the line from the dock or mooring. To move out.

Cathead – where the anchor is secured near the bow.

Charts – charts on the water are the same as maps on land. Charting can be done on paper or electronically using ENC (Electronic Navigational Chart).

Come Around – turn into the wind.

Everyday Use: When referring to someone potentially changing their mind or opinion. “They’ll come around, you’ll see.”

Course – steering towards your destination.

Draft – the vertical depth of a yacht below the waterline. Knowing the draft helps to navigate through shallow water.

Dolphin – A group of pilings bound together by cables.

Fathom – a fathom is a unit of measurement for 6 feet or 1.8288 metres. A fathom is typically the length of rope that a grown man or woman can extend with outstretched arms. Before modern technology, depth was measured by counting fathoms and lowering the line into the sea.

Everyday Use: When trying to figure something out, you are trying to get to the bottom of it. “I can’t fathom why she would do something like that.”

Gunwale – the top edge on the side of a boat.

Heeling – When you’re heeling, your sails are filled and your boat is leaning over, being pushed by the wind. To reach top speed, you want to be heeling.

Iron Wind – a nickname for the engine of the yacht.

Jibe – a jibe is a more complex way of changing direction that requires moving the stern into and through the wind and moving the mainsail to the other side of the boat. After a jibe, the wind direction will have changed from one side of the boat to the other. Whether you choose to tack or jibe entirely depends on the situation, what’s around you and the direction of the wind.

Everyday Use : To complement or match with something. “Your story doesn’t jibe with his story.”

Chicken Jibe – tacking more than 180° to avoid a jibe is sometimes called a chicken jibe.

Kedge – A small anchor used to change the direction or pivot point. Can also be used as an additional anchor in bad weather.

Lazy Jack – A bag attached to the boom for the mainsail to fall into.

Lines – on a yacht or any type of boat, ropes become known as lines.

Mainstay – the main line that is used to support a mast.

Everyday Use: An essential part of something. “A good quality engine is the mainstay of a yacht.”

Payout – to add slack to the line.

Reefing – reining in the sails during periods of strong wind.

Tack – tack is used as both a verb and a noun.

Verb: to change direction by turning the bow through the wind.

Noun: the course you are on, relative to the location of the wind. You are either on a starboard tack or a port tack, depending on which side the wind is blowing.

Three Sheets to the Wind – sailing with all of your sails (sheets) unsecured.

Everyday Use: Used to describe someone who is thoroughly drunk. “I heard Bob was three sheets to the wind last night.”

True Wind – Wind as measured on land, as opposed to how wind appears on a moving yacht (known as apparent wind).

Weigh – Raise the anchor.

Everyday Use: Getting something underway. Contrary to popular belief, the phrase is “anchors aweigh”, rather than “anchors away”  

Windlass – the winch used to raise the anchor
