ABSTRACT:
A training device for teaching individuals the proper positioning of a sailboat's boom relative to the boat in a given wind. The device has three planar members, a front (base) member indicating wind position and having sailing terms printed therein, a second planar member representing the boat and a third planar member representing the boom of a sailboat. Three axis members interconnect the planar members for proper relative rotation. The first axis member secures the free end of the boom to the base member. The second axis member fixes the second planar (boat) member for rotation about the base member. The third axis member fastens the front end of the third planar (boom) member to the second planar (boat) member and allows some relative rotation.
