The GP14 originally sponsored by the Yachting World magazine, was designed by Jack Holt in 1949 for home construction from the then comparatively new material of Marine Plywood. It was conceived as a General Purpose dinghy, and although equipped with wooden mast and boom, and with cotton jib and mainsail. It was also excellent to row, and had a standard conversion for fitting a small outboard motor.

Wooden Series 1 Hulls

These are built to Jack Holt’s original design, with a ply skin on frames, traditionally mahogany, but many other hardwoods were used. The centerboard case was made of solid mahogany and sat on top of the hog, and the mast had a square heel plug which sat in a box on the hog. Floorboards were generally three narrow planks each side, but most boats now have plywood sheets up to 380mm wide. The only regulation governing bow buoyancy tanks is that they must not come back behind frame 2 (the aft edge of the foredeck). Within that rule, there are several variants, some quite complicated to build, but the best is probably a tank formed by a single bulkhead fitted against the deck beam about 200mm in front of frame 2. Built- in buoyancy under the rear deck is unsatisfactory as it is difficult to fit transom scuppers, and the boat may therefore be difficult to manage after capsize. These have proved very long-lived, and many boats of the first 100 built are still regularly sailed at over 40 years old. Many of the earlier boats are amateur built, and they may be better, or they may be worst, than professionally built boats. All wooden boats up to 1990 were built in this way, and several more have been built since, both amateur and professional.
