ABSTRACT:
Wind propelled apparatus employing a mast and a sail, in particular a windsurfer for boardsailing is provided with a first boom, rigged in the usual fashion, and also having a second boom of reduced length and span rigged below the first boom, for use by a child, simultaneously with an adult operating the first boom. This double boom rig permits a child to learn the sport, be it ice boating, skateboard sailing, or the preferred windsurfing, under truly live conditions, while overcoming the greatest, and virtually insurmountable problem of uphauling, when the spar and sail are hauled up out of the water into a sailing attitude. The sail window is extended downwardly, or a junior sail window can be provided at the appropriate height. The attachment of the second, small size JUNIOR (TM) boom can be effected by recessig the sail, or by use of a power clamp or power clamps to the spar or to the sail, or to both. In addition to providing first hand, realistic boardsailing, direct and effective communication between the child and the instructor is assured.
