  • Patent number: 4082049
    Abstract: A sailing frame is disclosed which, in the preferred embodiment, is adapted to mount on an inflatable boat. The frame can be disassembled and/or folded into a small package for storage, compatible with the deflated boat. The frame assembles into a rigid configuration which mounts on the gunwales of the inflatable boat. Mounting members for a collapsible mast and sails are provided. The frame can include a mounting for a rudder. The sailing frame includes a pair of vertically extending dagger or bilge boards which, in the water, provide fore and aft stability to the boat and resist lateral forces. In alternative embodiments, the frame can be mounted on any other small boat or dinghy, and, when not in use, can be disassembled and stowed.
