Garden design #571.
LOD: 42.33'
*Original plans for wood construction, concrete keel and outboard rudder. Many built by professionals and amateurs around the world.
A number of GRP production yachts, especially built in the Far East, were based on this design, to which, according to the designer many "additions and refinements have been made to develop her into a most able and complete vessel".
Cutter and schooner versions were produced as well.
