International Twelve Foot Dinghy
Designed by George Cockshott
The International Twelve Foot Dinghy was drawn by George Cockshott, an amateur designer from Southport, to win a 1912 Boat Racing Association contest for a 12 ft dinghy with a single sail of 100 sq ft. Built from 1913, it became one of the first international one design classes, was sailed at the 1920 and 1928 Olympics, and is still raced keenly in Italy, the Netherlands and Japan.
The original specification calls for a clinker hull planked in spruce on steamed timbers, built over moulds taken from the full size drawings, with a beam of 4 ft 8 in, a standing lug rig and a hull of about 230 lb. Wooden boats are still built to it today, and the rules forbid a newer material from making a lighter boat, so an old wooden Twelve is not outclassed. The class association keeps the drawings and the 1913 specification.
What building a International Twelve Foot Dinghy actually takes
Medians from the build logs kept on this site, not the designer’s estimate. Nobody has logged this boat here yet, so they are empty until the first builder does.
Those medians firm up as more people log this boat.
