ABSTRACT:
A watercraft lift of the type which is connected to a mooring location comprises a mounting and a guide. The guide mounts an elongate reciprocating member which is raised and lowered by means of a winch. At the lower end of the reciprocating member is a support bracket which is adapted to receive the watercraft. In an alternate embodiment of the invention the mounting and the guide means are hingedly connected so that the lift pivots approximately one hundred and eighty degrees so that the watercraft may be moved into and out of the water and also may be placed on the support bracket when not in use.
