Kite for sea life-saving gear - has one diagonal inflatable tube on underside and second tube crossing over it, linking ends of leading edge tubes

摘要

The kite is rectangular in plan with tubular inflatable chambers along two sides. From the nose corner between these chambers a further tubular chamber (5) runs diagonally along the kite undersurface, forming a longitudinal keel. The rear ends of the edging chambers (6, 7) are linked by a tube (8) along the other diagonal, above the surface whereit crosses the first. Tube material is one or more layers of plastics foil, or plastics-impregnated fabric, as used for the rest of the kite. The surface is metallised, pref. aluminum-plated. The kite may have a common point for three converging hold lines, which may be used also for tow-line.
