Grampian 26 is a 25 ′ 11 ″ / 7.9 m monohull sailboat designed by Alex McGruer and built by Grampian Marine between 1967 and 1977.
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
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
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
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
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 )
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)
Grampians most popular model and one the most successful boats of this size built in Canada. A keel/cb version was also produced in small numbers. Rarer still is a raised deck version, called the DISCOVERY 7.9, introduced in 1979. Grampian offered a Palmer (gas) inboard as an option. Displacement and ballast shown here are as stated for keel version on introductory brochure.

In 1963 it added the 27-foot Eagle sloop and Triangle 32, and in 1965 the Classic 31, Walton 37 and U.S. Yachts 41. The Grampian 26 was introduced in 1969 and continued in production until 1987, an astounding 21-year run.

The Grampian 26 has a soft sheer and sweet hull shape with a spoon bow and counter stern. These features are often overlooked because of the high-sided, boxy cabintrunk and ample freeboard. However, the big cabintrunk was a major reason for the boat's popularity as it produced headroom, light and a sense of spaciousness below.

The boat was in production from 1967 through 1977, and according to McGruer, just over 1,000 Grampian 26s were built during that decade. (Nearly 200 were ordered during the first year alone.) Taddle Creek Yachts, of Toronto, tried unsuccessfully to revive interest in the design in 1987, but it seems new boat buyers were looking for a more ...
Our vessel was not some gold-plated, high-tech machine, but the humble Grampian 26, hull #688, a fixed-keel version called Lineva II built in 1974 and now owned by John and Linda McFetrick, members of Alexandra Yacht Club in Toronto.

bljones. 8473 posts · Joined 2008. #9 · Jul 26, 2012. Grampian, hands down. It is a BIG 26' boat while the Seafarer is the opposite- a smallish 26' boat. The difference really shows up in the v-berth. The Grampian v-berth is spacious and bright with enough room to sit up, the Seafarer's is a tight narrow dark cave.

This next one is real interesting..

Scott's Boat Pages March 29, 2002 By Scott B Williams SNIPPETS: ....I drove to the Tampa/St. Petersburg area with cash in hand..Most of these boats were either too run-down for the asking price if they were big enough to meet my needs, or too small or lacking in sea going quality if they were in great condition..
The Grampian 26 was designed by Alex McGruer in 1967. McGruer is part of a boatbuilding dynasty that reaches back to 1911, when the family business was located on the Clyde Estuary on the west coast of Scotland. The Grampian hills of his native land gave the name to this line of boats, which also includes the McGruer-designed 30-footer.
The Grampian 26 has been built with different keel alternatives. Fin keel. One option is a fin keel. A boat with a fin keel is more manoeuvrable but has less directional stability than a similar boat with a full keel. The boat can enter even shallow marinas as the draft is just about 1.28 - 1.38 meter (4.20 - 4.50 ft) dependent on the load.
