The Discovery 7.9 is a development of the Grampian 26.[1][3]
Production
editThe boat was built by Grampian Marine in Canada between 1975 and 1977, but it is now out of production. Only a small number were completed.[1][4]
After Grampian's end of production the molds were acquired by a new company who built a small number of boats with different window arrangements.[4]
Design
editThe Discovery 7.9 is a small recreational keelboat, built predominantly of fiberglass, with wood trim. It has a masthead sloop rig, a raked stem, a vertical transom, a transom-hung rudder and a fixed fin keel. It displaces 5,100 lb (2,313 kg) and carries 2,300 lb (1,043 kg) of ballast.[1]
The boat has a draft of 3.75 ft (1.14 m) with the standard keel fitted.[1]
The design has a hull speed of 6.25 kn (11.58 km/h).[5]
