. It displaces and has positive flotation buoyancy tanks, making the boat unsinkable. The boat has a draft of with the daggerboard extended and with it retracted, allowing operation in shallow water, beaching or ground transportation on a trailer or car roof. In 1998 W. D. Schock Corp carried out a redesign of the boat, as part of their program of modernizing many models in their product line, to simplify production and also maintenance for owners. The changes were made in consultation with the class association and the new design complies with class one design rules. The wood that had been used for the rails, thwarts, flotation tanks and other components was replaced with fiberglass, thus eliminating requirements for varnishing and reducing weight. The wooden tiller was replaced with

Operational history

The United States Sailing Association describes the boat, "Lehman 12 Dinghies have been a staple in Southern California one design racing since its inception in 1953. Lehman 12s are very responsive to weight, trim, and steering making it a challenging and competitive class. The Lehman 12 class is still one of the most active racing dinghy classes in Southern California." Ullman Sails says, "the Lehman 12 is an exceptionally responsive two-man planing dinghy that quietly glides through the water with only a whisper of wind. It is a daggerboard boat with a loose-fitted cat rig and a deep rudder. The simple, uncomplicated design of the Lehman 12 makes it great for the husband-and-wife team."
