Grampian 30

• By Bryan Allen

Grampian 30 368

Jim Bisiker founded Grampian Marine Ltd. in the early 1960s in Ontario, Canada. At one point, the company operated a second plant in North Carolina. After building boats to the plans of several designers, Grampian took on Alex McGruer to design the Grampian line in-house. Before closing in the late 1970s, it built about 400 Grampian 30s, 50 of them cutters.

From its reverse stern to its spoon bow, the Grampian 30 has a springy sheer and sweet lines. The cabin trunk is clearly of 1970s vintage, but considering that the boat is a shade under 30 feet and has 6 feet 4 inches of headroom, McGruer did well to keep it from looking overly chunky.

For a boat its size, the Grampian 30 has ample accommodations. Its conventional layout contains a large, long quarter berth to port, which is a great sea berth. To starboard is an L-shaped galley. Some owners have upgraded from the two-burner alcohol stove to one with a full oven. Others have added refrigeration to the icebox, which is accessible from both the galley and the cockpit.

On the port side of the saloon, the dining table drops down to convert the U-shaped settee into a double berth. The table contains stowage for charts and doubles as the chart table. The settee to starboard is the only berth with which someone taller than 6 feet might struggle. Large portlights keep the area light and airy.

Forward of the saloon, a small head is on the port side; opposite it, there’s a hanging locker with a shelf above. The forward cabin has a V-berth that’s long and wide; bins, drawers, and shelves are available for stowage.

The cockpit is large enough for a tall person to stretch out easily and, with the tiller hinged up out of the way, will seat several people comfortably. (A few boats have been converted to wheel steering.) The two 1-inch-diameter cockpit drains are adequate for rain but a little slow for a boarding wave. Some owners have enlarged them or added new ones. Overall, owners seem pleased with the sailing performance of the Grampian 30. It’s stiff and dry, even the centerboard version, but given its high ballast ratio (.45), it’s not hard to see why. It won’t outpace or outpoint more modern designs, but it balances well and, on a close reach in moderate conditions, will track for hours with no one at the helm.

A few items on the G30s might require some attention. The original aluminum stemhead fitting should be replaced with stainless steel. The bedding around the portlights may need renewing. Water can leak around the chainplate from the port-side cap shroud and soften the main bulkhead to which it’s bolted. This area is hidden beneath the fiberglass tabbing between the bulkhead and the hull. All the other chainplates attach to built-up fiberglass tabs integral to the hull and are strong, though many owners have added backing plates.

Access to the forward half of the engine is good, but the transmission and the stuffing box are both difficult to reach, prompting some owners to cut a watertight hatch in the cockpit sole.

Despite the strong build of the Grampian 30-materials were inexpensive in the 1970s-it falls into the coastal-cruiser category. That said, several have made long bluewater passages.

Much of the Grampian 30’s original appeal was that it was a lot of boat for the money. At current prices of between $12,000 and $15,000 (with a few outstanding examples above $20,000), it still is, and many have been improved or repowered. Grampian owners support a very helpful website ( www.grampianowners.com ).

Grampian 23

The grampian 23 is a 23.25ft masthead sloop designed by alex mcgruer and built in fiberglass by grampian marine between 1971 and 1976., 450 units have been built..

The Grampian 23 is a light sailboat which is a reasonably good performer. It is reasonably stable / stiff and has a low righting capability if capsized. It is best suited as a day-boat. There is a very short water supply range.

Grampian 23

Grampian 23 is a 23 ′ 3 ″ / 7.1 m monohull sailboat designed by Alex McGruer and built by Grampian Marine between 1971 and 1976.

Rig and Sails

Auxilary power, accomodations, calculations.

The theoretical maximum speed that a displacement hull can move efficiently through the water is determined by it's waterline length and displacement. It may be unable to reach this speed if the boat is underpowered or heavily loaded, though it may exceed this speed given enough power. Read more.

Classic hull speed formula:

Hull Speed = 1.34 x √LWL

Max Speed/Length ratio = 8.26 ÷ Displacement/Length ratio .311 Hull Speed = Max Speed/Length ratio x √LWL

Sail Area / Displacement Ratio

A measure of the power of the sails relative to the weight of the boat. The higher the number, the higher the performance, but the harder the boat will be to handle. This ratio is a "non-dimensional" value that facilitates comparisons between boats of different types and sizes. Read more.

SA/D = SA ÷ (D ÷ 64) 2/3

• SA : Sail area in square feet, derived by adding the mainsail area to 100% of the foretriangle area (the lateral area above the deck between the mast and the forestay).
• D : Displacement in pounds.

Ballast / Displacement Ratio

A measure of the stability of a boat's hull that suggests how well a monohull will stand up to its sails. The ballast displacement ratio indicates how much of the weight of a boat is placed for maximum stability against capsizing and is an indicator of stiffness and resistance to capsize.

Ballast / Displacement * 100

Displacement / Length Ratio

A measure of the weight of the boat relative to it's length at the waterline. The higher a boat’s D/L ratio, the more easily it will carry a load and the more comfortable its motion will be. The lower a boat's ratio is, the less power it takes to drive the boat to its nominal hull speed or beyond. Read more.

D/L = (D ÷ 2240) ÷ (0.01 x LWL)³

• D: Displacement of the boat in pounds.
• LWL: Waterline length in feet

Comfort Ratio

This ratio assess how quickly and abruptly a boat’s hull reacts to waves in a significant seaway, these being the elements of a boat’s motion most likely to cause seasickness. Read more.

Comfort ratio = D ÷ (.65 x (.7 LWL + .3 LOA) x Beam 1.33 )

• D: Displacement of the boat in pounds
• LOA: Length overall in feet
• Beam: Width of boat at the widest point in feet

Capsize Screening Formula

This formula attempts to indicate whether a given boat might be too wide and light to readily right itself after being overturned in extreme conditions. Read more.

CSV = Beam ÷ ³√(D / 64)

The GRAMPIAN 23 was available with either a swing or fixed fin keel.

Let's Get to Know Each Other

Let's connect, grampian 26 sailboat.

Built-in 1967, the Grampian 26 is a Canadian sailboat, which Alex McGruer designed. It was developed into the Discovery 7.9 in 1975 and which was built in a relatively smaller number. Grampian 26 was first built in Grampian Marine in Oakville, Ontario, Canada, between 1967 and 1977. Around 980 examples of Grampian 26 were completed, and the boat was known to be the most successful design in this size range.

The Canadian Sailor With the Best Value

Grampian 26 is a small recreational keelboat and made mainly of fiberglass along with wood trim. The masthead sloop rig, a raked stem, an internally mounted spade-type rudder, a fixed fin keel or centerboard, and a vertical transom.

There is a design that is optionally factory-equipped with a Palmer gasoline engine, or it can be equipped with a small outboard motor used for maneuvering and docking. The freshwater tank has a capacity of 20 U.S. gallons (76 L; 17 imp gal).

Grampian 26 has had a number of successful sails down the Atlantic Ocean, and it was once sailed for two years from New York to Europe. It is a 26 foot boat with a big cockpit, standing headroom along the length of the cabin, and bigger than normal v-berths.

Grampian 26 is known for its best price/size ratio on the used market. The cabin below has a dinette arrangement on the port side and a galley along the starboard side.
