  • Patent number: 5778814
    Abstract: A sunfish boat boom is slidably secured to a pipe tee for aft and bow relative motion to the tee which is secured to the mast by a conventional gooseneck device. A bungee cord secured to the boom at a pulley medial the boom between the mast and the aft end of the boom and to an eyelet at the pipe tee resiliently biases the boom in the bow direction. A rope is secured at its opposite ends to the bow end of the boom passing through an eyelet at the tee and to a cleat at the pilot compartment. Rings on the boom establish maximum aft and bow displacement of the boom via abutment with the tee. The rope holds the boom at an extreme forward position with the tee abutting one of the rings. The rope is released to permit the bungee cord bias to pull the boom to the other extreme aft position established by the other ring abutting the tee. Pulling or releasing the rope moves the boom to any desired position between the extreme positions.

  • Patent number: 5779509
    Abstract: A rigid, arched disk (10) is placed convex side down in a cloth skirt (12). The cloth skirt includes an annular bottom portion (20) which covers the convex surface of the disk and a curved upper portion (22) which ends in an annular reinforced upper edge (24). The annular upper edge (24) is smaller in diameter than the outer periphery of the arched disk (10). A zipper (28) in the skirt enables the upper annular edge to be expanded to receive the arched disk. An inflatable tube (14) is inserted into the skirt resting on a concave surface of the disk adjacent its periphery. The inflatable tube is inflated with a sufficient pressure to lock the tube, the skirt, and the disk against moving relative to each other. When the assembly sits still in the water, water flows into the concave surface of the disk through an aperture (16). When pulled by a tow rope connected with a pull loop (30), the convex surface of the disk lifts the device up out of the water, allowing water to drain through the aperture.

  • Patent number: 5775965
    Abstract: A device for quickly releasing a surfboard tether from a body strap. The tether and surfboard are normally connected by a plug and socket swivel connection. The device comprises a removable locking pin which, in its locked position, extends through openings in the socket and through a passage in the plug to secure the plug and socket connection. A resilient retainer acts against the socket body and the locking pin to normally retain the locking pin in its locked position. The locking pin is adapted to be pulled out of the passage and socket body against the urging of the resilient member to release the plug and socket, thereby disconnecting the leash from the body strap. In one embodiment of the invention the resilient member comprises an elastomeric band which is looped around the locking pin and the socket body and acts against a surface of the locking pin provided for that purpose to urge the locking pin into the locked position to hold the plug and socket in connection.
