Navigation lights on a sailboat can be confusing. If you understand the reason behind why they are the way they are however, they can make a lot more sense.
At their heart, sailboats are really just a power boat and as such must adhere to all power boat rules such as navigation lights. Other times however, a sailboat is classified in a special category. They have a set of additional lights they CAN show as an option, but are not always required to do so.
That’s about as clear as mud if you ask me and I contend that that is where the confusion about lighting a sailboat begins.
Just because you can show a light to identify yourself in times of low visibility, does not mean you have to and then we add in a little sibling rivalry between power and sail and things get downright adversarial when it comes to navigation and the night.

The USCG says You’re a Power Boat Whether You Like It or Not
Much to the consternation of many a sailor who has earned a commercial license to drive their sailboat, when you received your credential from the USCG it says you are a master of steam and power across the top with no mention of wind as a source of propulsion.
It is not until you read the back pages of your little red book that feels like a passport and looks like a US Sailing credential, that you will see the term “sail auxiliary”. That is because most of the time the U.S. Coast Guard knows that you are primarily reliant on your mechanical power to propel your vessel.
It's a sad thing, but the days of commercially viable sail boats are done and all but the most select few even have sails let alone use them as their primary power source. All sail boats by law are powerboats, but not all powerboats are sailboats.
Navigation Lights for a Power Boat
As a power boat, you are required to show certain lights and have been required to do so before power was even invented.
In the days of man powered vessels like the viking ships who relied on oars while in close quarters to power their vessels, they needed to show other boats, friend or foe, where they were by showing lanterns in the dark to identify themselves. As you know, it is a time honored rule among all the nations of the world both past and present, that you must avoid a collision at all costs while at sea and even the viking knew that you should not run into things.
By lighting the front and back of your boat, you could warn other boats of your presence as well as identify which way you were heading. As such there is a very specific rule in the Code of Federal Regulations Number 46 (CFR46 by common name) that spells out with detail how many, the color, the luminosity or brightness, the angle of visibility and the location of all of the lights required for navigation on every single boat, seaplane, submarine and other nondescript vessel conceived by man to date that they must show while underway in reduced visibility.
And there is no flexibility in the rules.
As such a power boat, and by extension all sailboats, MUST, without question show one green light on the starboard bow and one red light on the port bow and one all around white light or lights while operating in reduced visibility. These lights should shine at all 360 degrees of visibility with the bow lights shining at an angle of dead ahead to 22.5 degrees abaft the beam and the stern lights shining 225 degrees dead aft. A forward facing masthead light that is white in color shall shine forward to comply with the directive that all vessels must carry an all around white light. For more read here .
As you can see, there isn’t much wiggle room when it comes to lights that must be shown.
Sailboats get a little flexibility with lights
Sailboats however, are a little different when they are in fact sailboats, which is only when you are entirely reliant on the wind for power and in no way reliant on any mechanical or manual means of propulsion. And for good reason.
Back in the day when men were men and sailboats were wooden, fire was a major concern. Sails were coated with wax and other flammable substances and the wood on boats was saturated with oils and grease. Even the ropes were plant materials saturated with oils to keep them pliable and strong.
Add those highly flammable substances to a parching environment like the sea and you had what was essentially a giant floating tinderbox.
Then tell that giant floating tinderbox that they need to identify themselves to the world at large at night using oil lamps with flames because batteries and lights were not invented yet. It didn't take very long or very many ships burning to the water line for the Governments to say to the sailboats, you get to do things a little different.
As such, sailboats are given special dispensation when it comes to lights aloft. They don't have to show an all around white light in their rigging because no one wanted to set their rig on fire with oil lamps 60 feet up in their rig.
However, when a sailboat takes their sails down such as when they are powered or at anchor, they must resume the display of an all around white light or lights aloft. That became a real challenge with aluminum masts and the disappearance of rat lines on the shrouds because there was no easy way to climb the rig and check the bulbs up the mast on a regular basis.
Red over Green Sailing Machine
I have no idea where the history of this particular light comes from, but if you ever take a deck exam with the USCG, you better remember this mnemonic. An all around red light over an all around green may be displayed on a vessel during times of reduced visibility to indicate that a vessel is operating under sail power alone.
I won’t even speculate on how or why they came up with this particular light configuration, but if you want to use these lights as a sailing vessel, you can do so, but that means that you will need three all round lights at the top of your mast, an all around white, an all around red and an all around green, just in that order.
The red over green is to be displayed in addition to the running lights or the red and green bow lights with the 225 degree stern light. As always, when the motor comes on, so does the steaming light or the forward facing white light that is also usually about ¾ of the way up on your mast to complete the requirement of an all around white light that indicates a power vessel.
What is a “steaming light” and why are you mentioning it now?
Most sailboat electrical panels will have a switch that is labelled “steaming light” and it will only come on when your anchor light is off. This is probably the most confusing part of sailboat navigation lights so if you are confused about this, you're in good company as most people are.
A “steaming” light is named thusly, going back to the days of steam powered sailboats where when they fired up their boilers and doused the sails, they became a power boat once again. There aren’t too many steam powered boats, let alone steam powered sailboats, but the name stuck and it is a vestige of a bygone era.
Either way, when you fire up your motor, you turn on your “steaming light” and that locks out the all around white light which is used for anchoring to minimize the number of switches on your panel and reduce the number of wires in your mast. The fewer wires, the less chance of something not working or becoming disconnected.
The steaming light and the anchor light both go up the mast, but you can’t use an all around white light while using the 225 degree stern light at the deck level because to other boaters you would look like you have two white lights from the stern and that would be confusing.
The anchor light is used exclusively for anchoring while the steaming light is used to indicate you are a power vessel while underway.
As to why I am mentioning it now in the article, is because this would have blown your mind if I started with this subject cause it can be really confusing stuff.
Aspect Recognition with Lights
Remember when I said earlier that lights can help you tell others which way you are heading as well as tell you which way other boats are heading? That is called the aspect of the vessel and the USCG tests you on this for your deck exam as well.
Knowing that the bow lights go 22.5 degrees abaft the beam on both sides or 112.5 degrees on each side, and the stern light faces 225 degrees aft for a total of 360 degrees of visibility, you can tell a lot about where a boat is heading and who has the right of way.
One thing that's easy to remember is red means stop and if you see a vessel's red light, it means stop as you are the give way vessel and approaching the other vessel from his port side. Conversely it works with green as well as that means you are approaching from the other vessel's starboard side and you are the standon vessel.
If you see a red and green light equally low on the horizon, that means your heading dead on into another vessel's path and conversely if all you see is a white light low on the horizon, it means you are overtaking another vessel power or sail, we don’t care because it is an overtaking situation. However, any time you do see a white light aloft in addition to the red and green bow lights, you know you are encountering a power boat.
Then there are angular approaches as well, where you see white and red or white and green light low on the horizon. You know in that case you are seeing a portion of the bow lights and stern lights from the side approaches of a vessel. Based on which direction those lights are heading, you can deduce which way that boat is going in relation to your boat.
So put it all together and you see a green light and a white light low on the horizon with a red over green light aloft, you know that you are approaching a sailboat that is traveling to your port and that might make you the standon vessel. That is of course, if we didn’t concern ourselves with windward and leeward and port tacks and starboard tacks, but that is a discussion for another article. So stay tuned when we talk about sailing rules and the right of way. But for now, do good, have fun and sail far.

The white, forward-showing light carried by a powered vessel by night or in bad visibility. In the Collision Regulations this is called a ‘Masthead Light’ (though not required to be carried at the masthead) and it must show from dead ahead to 22.5 degrees abaft the beam on each side. A vessel of less than fifty metres length may show one such light: those longer must show another similar light farther aft and higher up. A boat under sail does not show a forward white light.

Steaming Light
Definition of steaming light.
A steaming light is the white, forward-pointing light that a motorized watercraft carries at night or when there is poor visibility.
It’s also known as a masthead light or mast light .
According to COLREGs , the collision regulations, a power driven vessel that is underway , must have a steaming light visible from directly ahead to 22.5 degrees behind the beam on either side.
In addition, a boat under 50 meters long may have one steaming light, but larger boats must show a second, similar light set farther back and higher up on the boat to increase visibility.
It’s important to pick a light visible for 2–3 nautical miles . The LED Masthead Lamp is a long lasting, energy efficient light that is compliant with this rule thanks to its 3 NM and 5 NM options.
A sailboat doesn't have a steaming light but may display a tricolor light at or near the top of the mast.
The LED Tri-Color with Anchor Lamp lights green (starboard), red (port) forward, and white towards the stern.
Example of Steaming Light in a Sentence
"The steaming light on the front masthead of the boat provided clear visibility of its direction of travel to nearby vessels."
Synonyms: mast light, masthead light

Sailboat Steaming Light: A Crucial Navigation Aid for Safe Night Sailing
by Emma Sullivan | Aug 12, 2023 | Sailboat Maintenance
Short answer sailboat steaming light:
A sailboat steaming light is a white, forward-facing light used to indicate that a vessel is underway under power during nighttime or restricted visibility conditions. It is typically mounted on the mast or near the navigation lights and helps other vessels identify the sailboat’s position and direction.
What is a Sailboat Steaming Light? A Comprehensive Guide
Sailing enthusiasts, both experienced sailors and newcomers to the sport, often come across various terminologies associated with boats and their equipment. One such term is the “steaming light.” In this comprehensive guide, we will delve into everything you need to know about a sailboat steaming light and its importance.
So, what exactly is a sailboat steaming light? A sailboat steaming light refers to a white navigation light mounted on or near the front of a sailing vessel. It serves as an essential safety feature when sailing during low visibility conditions, such as at dusk or dawn. When turned on, the steaming light ensures that your boat remains visible to other vessels in order to prevent collisions.
The primary purpose of a sailboat steaming light is to indicate to other boaters whether your vessel is under power (engine) or not. This becomes crucial when sharing busy waterways with motorized boats that may have limited maneuverability compared to sails .
In addition to indicating if your boat is powered by an engine, the sailboat steaming light often works in conjunction with another essential navigation light called the bow (or sidelight). The combination of these lights helps mariners determine which way your boat is moving – whether it’s coming towards them or moving away from them.
According to international marine regulations (COLREGs), all sailing vessels are required to display proper lighting for navigation and collision avoidance purposes. This includes having a functioning steaming light mounted at least 1 meter above the vessel’s deck level and visible up to 3-5 nautical miles depending on the size of your boat.
It’s important to note that while many modern boats come pre-equipped with built-in lighting systems compliant with maritime laws, older or custom-built vessels might require additional modifications or upgrading for compliance. Therefore, it is advisable for boat owners to familiarize themselves with their specific country’s regulations to ensure they meet the necessary requirements .
Now, let’s talk about some clever tips and tricks regarding sailboat steaming lights.
Firstly, in order to maximize visibility, it is crucial to keep your steaming light clean and free from any obstructions. Regularly inspect the light for dirt, corrosion, or damage that might hinder its performance. Even a small layer of grime or a cracked lens can significantly reduce its visibility range, potentially jeopardizing your safety on the water.
Another important consideration is understanding how to interpret other boats’ lighting signals. By being aware of what each navigation light represents and their combinations, you can quickly assess if an approaching vessel is likely to pose any risks. For instance, if you see a sailboat displaying only its red or green sidelight without a visible white steaming light , it suggests that it may be solely under sail power and not utilizing its engine. This knowledge allows you to anticipate their movements better and make quicker decisions when adjusting your own course.
Lastly, remember that having a properly functioning steaming light should never give you a false sense of security while sailing in low visibility conditions. Always exercise caution and maintain a lookout for other vessels by employing all available means such as radar or AIS (Automatic Identification System). Additionally, using common sense navigation techniques like reducing speed or altering course when necessary can go a long way in ensuring safe passage.
In conclusion, understanding the purpose and importance of a sailboat steaming light is vital for any sailor seeking to enjoy their time on the water while prioritizing safety. By adhering to international regulations and maintaining the integrity of this navigation tool through regular inspections and cleaning practices, you can navigate confidently during low visibility situations. So next time you set sail at dusk or dawn with your trustworthy vessel equipped with a reliable steaming light – stay informed, stay cautious, and most importantly – enjoy your adventure!

Navigation Lights on Sailing Yachts and Motor Boats
Navigation lights ensure the safety of everyone at sea. The Convention on the International Regulations for Preventing Collisions at Sea (IMO COLREG 72) precisely sets out the guidelines for navigation lights, i.e., displaying lights, their range (distance from which the light is visible), as well as how they should be constructed and assembled. Our guide is of interest to sailors and sports boats enthusiasts with boats up to 20 m in length.
Regulations and official certifications:

What are the advantages of LED navigation lights?
Switching from conventional to led navigation lights.
According to COLREGs part C, rule 20), navigation lights must always be used on board from sunset to sunrise or during the day if visibility is poor.
Please refer to the German Traffic Regulations for Navigable Maritime Waterways , §8 -10 and Preventing Collisions at Sea. Part C - Lights and Shapes. rules 20 - 31, and annexes I 1. - 14 for the exact wording.
NOTE: Vessels that are authorised to fly the German flag are generally only permitted to use approved navigation lights and sound signalling devices.
EU approval can be identified via the wheel mark symbol and the notified body number. BSH approved navigation lights (previously DHI) are marked with a model number (e.g., BSH/00/01/90).
However, even older lights with DHI approval that have already been installed maintain their approval, despite the changes made by the BSH.
In addition to the wheel mark symbol and German BSH approval, some lights are also approved by other countries, such as RINA (Registro Italiano Navale), MCA (Maritime and Coastguard Agency) and the USCG (United States Coast Guard). These are now recognised, provided the approval comes from the national approval body recognised in the country of origin.
National bodies whose accreditation is currently recognised in Germany:
| Canada: | Marine Safety Directorate |
| China: | CCS China Classification Society |
| Denmark: | Danish Maritime Authority |
| Finnland: | Finnish Maritime Administration |
| France: | Bureau Veritas S.A. |
| England: | Marine Safety Agency |
| Greece: | Ministry of Merchant Marine |
| Iceland: | Icelandic Maritime Administration |
| Italy: | Registro Italiano Navale |
| Japan | Nippon Kaiji Kyokai Material & Equipment |
| Croatia: | Croatian register of Shipping |
| Netherlands: | Directorate-General for Freight Transport, Shipping Inspectorate |
| Norway: | Sjofartsdirektoratet, Norwegian Maritime Directorate |
| Poland: | Polski Rejestr Statkow S.A. |
| Russia: | Russian Maritime Register of Shipping |
The wheel mark symbol indicates approval of the Marine Equipment Directive (MED). This approval is valid for all EU member states, both for commercial vessels and recreational shipping.
0098 = Notified Body number (here 0098 = Germanischer Lloyd in Hamburg) 18 = year in which the mark is affixed, here 2018
- A CE mark is a symbol that must be affixed to a product by the manufacturer before it is sold on the European market. It indicates that the manufacturer is aware of the specific requirements for the product in question and that it fulfils the requirements of relevant European product directives. A CE mark does not supersede approval according to collision prevention regulations.
- Navigation lights are defined in detail by the International Maritime Organization (IMO), according to the International Regulations for Preventing Collisions at Sea, 1972 (COLREGs) Convention on the International Regulations for Preventing Collisions at Sea, 1972), in sections C and D. The following rules apply:
Which navigation lights are required on board according to IMO COL REG?
Definitions according to the 1972 International Regulations for Prevention of Collisions at Sea (COL REG 72):
1. Side lights for starboard and port
A green light on the starboard side and a red light on the port side, which shine from dead ahead in an arc of 112.5° aft to a point 22.5° abaft the beam (behind the beam) on either side of the vessel. On ships of less than 20 metres in length, the two individual sidelights may be replaced by a dual-colour combined light. This must be centrally located on the bow and stern axis.
2. Stern light
A white light mounted as close to the stern as possible and shines dead ahead in an arc of 135° (67.5° to each side). The mounting height should be aligned to the height of the side lights and should never be higher.
3. Three-colour light for sailing vessels (sailing lights)
On sail boats up to a length of 20 m, the side light and stern light can be combined into one three-colour light mounted on top of the mast. However, as soon as the sail boat's motor is engaged, the use of a three-colour light is no longer permitted. The rules for motor-powered vessels then apply.
4. Mast-head light
A white light placed over the centre line of the vessel and shines dead ahead in an arc of 225° (from straight ahead up to 22.5° more aft than crosswise to each side). The mounting height should be at least 1 m higher than the side lights. In the past, the mast-head light was also referred to as a steam boat light or steamer light, as it is only seen on ships that operate under engine power.
5. Signal light or all-round light
A light that shines in a complete circle of 360°. It may emit white, red or green light, depending on use. Examples of use: All sailboats and motorboats at anchor must exhibit a white anchor light . Ships over 12m in length must, if necessary, display vessel-in-distress lights (two red signal lights) placed at a vertical distance of at least 12 m. The distance between such lights must not exceed 1 m.
From what distance must navigation lights be visible?
The range indicates the distance from which the light can be seen. The minimum ranges of navigation lights are defined according to ship size as follows::
| Ships up to 12m in overall length | Range in nautical miles (NM) |
|---|---|
| Mast-head light | 2 NM |
| Side light (starboard /port) | 1 NM |
| Stern light | 2 NM |
| Three-colour light (sail boat when at sail) | 2 NM |
| All-round light (white, red, green all-round light) | 2 NM |
| Ships of 12 - 49 m overall length | Range in nautical miles (NM) |
|---|---|
| Mast-head light | 3 NM (up to 20 m) / 5 NM (from 20m) |
| Side light (starboard /port) | 2 NM |
| Stern light | 2 NM |
| Three-colour light (sail boat when at sail) | 2 NM |
| All-round light (white, red, green all-round light) | 2 NM |
| Ships from 50 m overall length | Range in nautical miles (NM) |
|---|---|
| Mast-head light | 6 NM |
| Side light (starboard /port) | 3 NM |
| Stern light | 3 NM |
| All-round light (white, red, green all-round light) | 3 NM |
Best-seller Hella Marine
Note: When sailing boats are powered by a motor, the rules for motorboats apply and not for sailboats. The tricolour light may then no longer be displayed.
Displaying lights for sailboats up to 20 m
1 x red port side light
1 x green starboard light
1 x stern light
Also allowed:
1 x red all-round light on or near the mast top
1 x green all-round light on or near the mast top
1 x 3-colour light
Sailing vessels under 7 m (dinghies or small sports boats)
If, due to their design, no modern lights can be fitted, sailing vessels under 7 m in length and vessels being rowed must always carry an electric torch or lantern showing a white light, ready to exhibit in sufficient time to prevent a collision.
1 x Electric light or a torch with white light
Motorised vessels over 12 m
Lights used must be either / or:
1 x white masthead light fore
1 x dual colour light
Motorised vessels under 12 m
Alternatively, motorised vessels under 12 m can exhibit the following lights:
1 x white all-round light
Motorised vessels under 7 m and 7 knots maximum speed (small motor boats, dinghies or inflatables):
Motorised vehicles under 7 metres and with a maximum speed of no more than 7 knots can display the following navigation lights: all-round lights, portside and starboard lights.
The following applies in accordance with German Traffic Regulations for Navigable Maritime Waterways (SeeSchStrO): If, due to their design, no lights can be displayed (e.g., dinghies), sailing vessels under 7 m in length and 7 knots maximum speed must carry an electric hand-held spotlight or a torch to prevent collisions in the dark.
Left: 1 x white all-round light, 1 x red port side light, 1 x green starboard light
Right: 1 x hand-held spotlight or torch

Provided no engine power is used, the rules for sailboats apply. Motor-sailing vessels must display a large black cone pointing downwards when sailing during the day or at good light.
For vessels travelling under sail or at rudder during darkness or at reduced visibility, the rules for carrying lights for motorised boats automatically apply. This then depends on the length of the boat.
By day with a black cone, tip pointing downwards.

Torches % Spotlights
How must navigation lights be mounted on board?
Navigation lights must be securely mounted perpendicular to the waterline. Mast-head lights and stern lights should both be placed above the keel line.
At anchor during daylight? This must be displayed with a black anchor ball.
If the vessel is anchored outside of an area of water known by the River and Shipping Police Authority as an anchorage and berth for small vessels, this must be indicated as follows:
A black ball by day, 1 x white all-round light at night
Anchor Lights
If your boat is unable to manoeuvre*, this should be indicated as follows:
Stationary: 2 x red all-round light, 2 x black ball, one below the other (during the day)
Moving: 1 x red port side light, 1 x green starboard light, 1 x white stern light
* A vessel is described as if, due to exceptional circumstances (e.g., rudder failure or engine malfunction), it cannot manoeuvre as prescribed and therefore cannot avoid another vessel.
How do I indicate correctly that my sailboat or motorboat has run aground?
If your boat has run aground, this should be indicated as follows:
2 x red all-round light, 1 x white all-round light, 3 x black ball, one below the other (during the day)
Manufacturers that specialise in navigation lights such as Aqua Signal or Hella Marine supply a wide range of internationally approved navigation lights which work with conventional (with BSH bulb) or with permanently installed light-emitting semiconductor components (LEDs). The bulbs required for operation are an integral part of the approval. Replacement bulbs must also be certified so that approval / your insurance protection is guaranteed. Ships under 20 m: Stern and anchor lights require BSH-approved light bulbs with 10 watts, all other navigation lights 25 watts.
| Spare light bulb for series | Stern l / Anchor l. 12 V/10W | Stb./BB, Masth / All-rnd l. 12 V / 25W |
|---|---|---|
| Aqua Signal, Serie 40 | SVB Art. Nr. 10203 | SVB Art. Nr. 10206 |
| Aqua Signal, Serie 41 | SVB Art. Nr. 10203 | SVB Art. Nr. 10206 |
| Aqua Signal, Serie 50 | SVB Art. Nr. 10203 | SVB Art. Nr. 10206 |
| Hella Marine, Serie 2984 | SVB Art. Nr. 10203 | SVB Art. Nr. 10206 |
All series listed above with BAY15d sockets could alternatively be operated with a high-Power LED . The big advantage in doing so is that the LED is suitable for multiple voltages (10-30 V) and consumes just 3 watts during operation. Since the light colour, range of light or beam angle can vary depending on the housing, this light is NOT yet internationally approved.
Spare Bulbs - Conventional & LED
Energy consumption on sailing ships is, as ever, a topic of significant interest. This is especially true for blue-water sailors who like to sail longer distances at a stretch. The arguments for converting to LED technology are as follows:
- High energy savings due to the low power consumption
- Long lifespan (over 10,000 hours)
- MultivoltTM technology (10-30V) with greater tolerance to voltage peaks
- Compact and light housing constructions
- Waterproofed, hermetically sealed housings
- Maintenance free
When switching completely from conventional navigation lights to LED lights, lights with the BSH seal of approval / EU wheel mark meet all the requirements in terms of light colour (no risk of blue tint), range of light and beam angle, and that you are travelling in accordance with KVR.
Navigation lights with LED technology
Replacing your navigation lights is often easy to do as manufacturers usually use the same mounting points for LED lights or have an adapter plate for further use of existing drill holes:
| Existing series: | New LED series: |
|---|---|
| Aqua Signal, Series 40 with quicfit socket | Series 34 with quicfit socket |
| Aqua Signal, series 41 | Series 41 (use identical drill holes) |
| Aqua Signal, series 40 and 50 | Series 43 using adapter plate, SVB no. 14557 |
| Aqua Signal, series 40 and 50 | Series 44 using adapter plate, SVB no. 14557 |

Ultimate Guide To Marine Navigation Lighting
If you drive a car or even ride a bicycle, you might be well aware of the necessity of lighting systems (though in the second case the word ‘system’ doesn’t quite apply) for the safety of you and the people around you. The thing applies just as well for ships. But since they are much larger than a car, the lighting system or navigation lights on ships is a little bit more complicated as well. Marine navigation lighting is also one of the most critical aspects of nautical studies.
It is mandatory for boats of all sizes to have a navigation system . This is to make sure that the chances of any significant accident are minimized. The United States introduced the system in 1838, and the United Kingdom followed suit. Before being internationally adopted in 1897 suitable guidelines were established by the International Maritime Conference which was established in 1889. Three colors were chosen that were to be used for the light colors. They were red, green and white. This was based on a set of rules specified by the US and are followed around the world to this date.
This article discusses the different rules and regulations of using navigation lights, their importance, and also some basic marine navigation lighting systems along with their positions and ranges.
Marine Navigational Lights, Rules and Regulations
A standard pattern of marine navigation lighting is followed for the identification of both the vessel as well as the IALA buoyage system at night. If you are required to move from sea to a channel you need to have a list of all the IALA as well as the other fixed navigational lights that are visible on entering the channel. This includes distant lighthouses as well.
If you also make a note of the inland features like the radio and television transmitter masts it will benefit you because they act as good navigational aids due to their height and warning lights.
The helmsman should not be using any bright light source in the cockpit area and should rather take the aid of red lights and very dim white lights in the galley and navigation area. This is because he needs to preserve his night vision so that he can accurately interpret both the buoyage marine navigation lights as well as the boat navigation lights of other vessels.
The nautical almanacs contain the details of each and every visible maritime light signal coming from navigational markers that are both inside and outside the channel.
All the details about any particular light can be found in a published list or on a marine navigational lights chart: its color, period, and in some cases even the elevation and range of the beacon. Use the chart to keep a tag on the lights you are passing by putting a tick mark on the lights that you are about to pass and as the boat sails past, the tick is checked.
You will get two visual clues to figure out how far you are away from a buoy. The light will elevate from the horizon at 0.5 nm and at about 200m, the light will reflect on the surface.
Position of Boat Navigation Lights
Most of the variations that can be found in the different vessels can be read about in most almanacs. At the very basic level, a vessel needs to show a red light to port and green light to starboard. Depending on the size of the vessel, one or more colored or white lights are used as well.
For vessels that are 12 ft in length or shorter, the navigation lights must be visible from a range of one nautical mile and for the ones that are longer than 12 meters the required visibility range is 2 nautical miles. From 5 degrees above to 5 degrees below the horizontal happens to be the required minimum intensity in a vertical sector.
International Navigation Rules state that the boat navigation lights should be placed above the uppermost continuous deck. In case separate fixtures are used for the red and green sidelights, the masthead or all-round white light is placed as close as possible to the vessel’s fore and aft centerline. The masthead or all-around light needs to be positioned at least 1 m or 3.3 ft above the sidelights.
Following are the basic positions of navigational lights. We will discuss the same in greater detail ahead.

Boat Navigation Light Regulations
Several rules and specifications are related to the type, size, layout, arc, and distance of visibility of boat navigation lights used by all vessel types which are collectively known as the International Regulations for Preventing Collisions at Sea or COLREGs . The navigational lights used are known as ‘COLREG lights and shapes. A boat might be anchored or underway, under sail or power, or fishing or trawling. These various situations can be communicated through multiple combinations of boat navigational lights.
In addition to the primary navigation lights, vessels may also display one or more steaming lights. These lights are very useful for it gives details about the various aspects of the ship like whether it is in the sail or under power, the direction in which it is going and, in some cases, even the size of the vessel. If a ship is engaged in a specific task that might involve certain restrictions, that too can be indicated with some extra boat lights.
Always maintain the lighting system and display the correct navigation light combination to make other vessels in the vicinity aware of your course and state as to whether your vessel is under power or not. If you follow this a considerable amount lowers the chances of a collision. Here is a list that you might use to familiarise yourself with the basics of the lighting system.
- Basic Navigation Light White Light : Small dinghies that are 7m or less in size are required to carry a torch having a white light that can be flashed when needed.
- All-Round White Light: An all-round white light is expected to be displayed by a small boat, up to 7ft long that is under power and can go beyond 7 knots of speed. This light must be visible at an angle of 360 degrees and from two miles away. An all-around white light is also used when the boat or vessel is at anchor but not at a designated anchoring area. This is to make sure that the ship is visible to all the nearby ships to avoid any accidents.
- Stern and Combined Side Lights : A stern light is a white light that is installed at the end of a boat. A vessel that is over 7 m or 23 ft in length is expected to show red and green sidelights when sailing. Each of these lights needs to cover an arc of 112.5°. The sidelights may be combined in one lantern at the bow when below 25 m or 65 ft. The white stern light can be seen over an arc of 135°. These lights need to be visible from a distance of a mile and need to be placed 39 inches below all white lights for boats of lengths equal to or less than 12 ft.
- Masthead Light : A combination of sidelight and stern light in a tricolor combination may be used sailing yachts of heights 20 m or lower. A masthead light is required by vessels of lengths between 39.4 ft and 65.6 ft. It is placed in the masthead whose height provides excellent visibility. Still, stern lights and sidelights should be fitted separately in case of or use under power along with steaming light. This kind of light needs to be visible across an angle of 225 degrees and from a minimum distance of 2 miles.
- Separate Lights : The displaying of the tricolor masthead light is not allowed in the case of yachts that are longer than 20 m or 65 ft. Instead, they use them separately. Often on large sailing vessels, these all-around, red over green lights are present. These red and green sidelights need to be visible from a distance of one mile and across an angle of 112.5 degrees.
- Steaming Lights Combined Lights : A combination of the masthead and stern light are used in the case of power crafts that are less than 20 m or 65 ft in length. The arrangement is present at the bow.
- Single Steaming Light : Visible over a 225 degrees arc, a masthead steaming light is used by power-driven vessels that are up to 50 m or 160 ft long. Separate stern lights and sidelights are used in case of a length exceeding 20 m or 65 ft.
- Two Steaming Lights: Power-driven vessels that span over 50 m or 160 ft in length display two masthead steaming lights. The forward light placed lower than the aft light with both of them being visible over an arc of 225° with the sidelights and separate stern light.
The area of the nautical lighting system is a precise business and requires some amount of study and a good deal of responsibility. It is because its application forms a core element in safe marine navigation.

A steaming light is a white navigation light fitted on the mast of a sailboat to provide visibility during low-visibility conditions. It is typically placed near the front side of the mast and angled downwards to indicate that the vessel is under power and moving forward. This light helps other boats identify and avoid collisions, ensuring safe ...
As such a power boat, and by extension all sailboats, MUST, without question show one green light on the starboard bow and one red light on the port bow and one all around white light or lights while operating in reduced visibility. These lights should shine at all 360 degrees of visibility with the bow lights shining at an angle of dead ahead ...
According to the navigation rules the steaming light/mast light should be 1 meter above sidelights. In reality, I have seen mast lights a few feet above the spreaders and a few feet below the spreaders. My mast is 28 ft long . I have already installed the anchor light on top of the mast. Now, I only have to install the steaming light/mast light ...
Powerboats that are less than 12m (39.4') may substitute a single all-round light for separate stern and masthead lights. Powerboats and sailboats under power that are less than 20m (65.7') can substitute a single bi-color light for sidelights. Sailboats When Under Sail. The basic rule is that sidelights and a stern light are required.
Aug 20, 2003. #2. Steaming Light. The steaming light is just that, it is used when steaming/motoring. If it is on, in conjunction with the stern light, then the boat is signaling that is under power to all other vessels. You must then abide by the navigation rules for a motorized vessel even if you are under sail only.
The light fixture is reversed. When steaming you should show a forward facing light for approximately 225 degrees. When you flick on the anchor light it will turn on both the steaming and rear facing to complete the 360 degrees. The wiring seems to be OK so you just need the reverse the fixture. Perhaps a 260 owner can tell you how it is attached.
All-round lights are white and shine through 360°. Masthead lights are white and shine from 112.5° on the port side through dead ahead to 112.5° on the starboard side. They must be above the sidelights. Sailboats under power are considered powerboats. Sidelights may be combined into a single "bicolor" light.
Steaming light. The white, forward-showing light carried by a powered vessel by night or in bad visibility. In the Collision Regulations this is called a 'Masthead Light' (though not required to be carried at the masthead) and it must show from dead ahead to 22.5 degrees abaft the beam on each side. A vessel of less than fifty metres length ...
A sailboat doesn't have a steaming light but may display a tricolor light at or near the top of the mast.

A sailboat steaming light is a white, forward-facing light used to indicate that a vessel is underway under power during nighttime or restricted visibility conditions. It is typically mounted on the mast or near the navigation lights and helps other vessels identify the sailboat's position and direction.
Stern light. A white light mounted as close to the stern as possible and shines dead ahead in an arc of 135° (67.5° to each side). The mounting height should be aligned to the height of the side lights and should never be higher. 3. Three-colour light for sailing vessels (sailing lights) On sail boats up to a length of 20 m, the side light ...
The most common of our navigation lights are our "running lights". This is a red light on the port side of the boat and a green light on the starboard side that shine from the bow to 22.5 degrees abaft the beam of the boat. This creates a 112.5-degree arc on either side of the vessel. To complete a 360-degree circle, our white stern light ...
In the case above where the steaming light is burned out, you must turn off the anchor light and show the stern light. If the observer knows the basic rules, there is no way to confuse a power driven vessel (sailboat with engine running) from a sailing vessel. The sailing vessel does not show a masthead (steaming) light.
Boat Navigation Light Regulations. Several rules and specifications are related to the type, size, layout, arc, ...

166. Hunter 386 Lake St. Clair. Nov 11, 2020. #1. Guys, we had to step the mast this autumn. Figure might as well change out those old bulbs and replace with Led's. I've attached some photos. The Steaming and Anchor both use, Aqua Signal 12V 25W Index base. Index just means the 2 prongs on the base are offset.
Only five lights rated good at 2 nm: Aqua Signal's 40100-1 bi-color light and 40400-1 masthead; Hella Marine's 62208 stern light, 62206 masthead, and 6225 tri-color.

If the boat is under power after dark, you'd need the bicolor/sidelights and either a stern light and steaming light, or an all-around white light, depending on the length of your boat. At anchor, you'd need an anchor light. At any of the above times you might want a foredeck work, like when anchoring. This gives you several options, like using ...
