ABSTRACT:
A lift harness for use in winching jet skis, boats and similar craft out from the water is described as including a pair of floatation pipes coupled to an overhead metal ring by a pair of fabric straps connecting the pipes and the ring in an "open-tent" configuration. In use, the floatation pipes in the water are manually held apart, the watercraft is guided between the pipes from behind, and the metal ring raised to a davit mechanically lifting the craft from the water in a construction where no metal parts contact the watercraft itself.
