发明名称 Twin Arm Gin Pole
摘要 A twin arm gin pole is an apparatus that is used for leverage when raising or lowering a deck stepped mast on a sail boat. The apparatus includes a first arm, a second arm, a first lifeline stanchion coupler, a second lifeline stanchion coupler, a winch, and a halyard connector. The first arm and the second arm are connected in a V-shaped structural body. Each of the distal ends for the V-shaped structural body is hingedly connected to the boat by one of the lifeline stanchion coupler. The winch is connected adjacent to the vertex of the V-shaped structural body, and the halyard connector is connected adjacent to the V-shaped structural body, opposite the winch. The winch is cranked to either pull the V-shaped structural body towards or away from the deck of the boat. A halyard line is tethered between the halyard connector and the top of the mast.
