ABSTRACT:
A boat hoist has longitudinally spaced lifting beams together with winch and cable means for raising and lowering the beams simultaneously by manipulation of a single hand wheel to move a boat straight up and down, there being a scissors support for each beam to insure smooth action and uniform movement throughout the length of each beam. The arrangement is such that the hoist may be employed to free the feet of the main frame from the lake bottom at the end of a season preparatory to removing the hoist from the water.
