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.

A lift harness for small watercraft, deployable by one person, comprising:
- a pair of floatation pipes having first and second opposite ends;
- a single connector;
- first and second fabric straps respectively coupling said connector to said pair of floatation pipes at a point adjacent to said first ends thereof;
- third and fourth fabric straps respectively coupling said connector to said pair of floatation pipes at a point adjacent to said second ends thereof;
- a fifth fabric strap coupled between said pair of floatation pipes at said point adjacent to said first ends;
- and
- a sixth fabric strap coupled between said pair of floatation pipes at said point adjacent to said second ends;
- with said first, said second, said third and said fourth straps being selected of substantially equal length, and with said fifth and said sixth straps being also selected of substantially equal length;
- with said pair of floatation pipes being fabricated of a plastic, foam-filled composition;
- and
- with the areas defined by said first, said second and said fifth straps and by said third, said fourth and said sixth straps being only slightly greater than the area required to encompass a watercraft resting on said fifth and sixth straps when deployed.
