I am restoring a pond yacht, built by my grandfather , James Melville and a Mr. Ingram in Tayport, Scotland, in the early 1930s. The hull is 55 inches long x 13 inches at it's widest point ( beam ). The mast is 62 inches tall and the boom is 33 inches long. She weighs 26lb. The measurements and weight and classic lines are consistent with a classic 6 Metre yacht design, popular with model yacht builders in the 1930s.
