ABSTRACT:
A combination cradle and davit lift for small lighweight boats, in particular inflatable boats, comprise a pair of shallow V-shaped tubular cradle members joined by longitudinal members. The longitudinal members are adjustable lengthwise and the cradle members are each adjustable widthwise on either side of the bottom of the V. Detachable hinges are provided for attachment to a swim platform or stern of a large boat. The cradle lift is constructed preferably of suitable hollow rigid plastic tubing for approximately neutral bouyancy whereby the cradles submerge with the outboardmost longitudinal member remaining above the water surface or, in the alternative, the cradle lift is provided with means to prevent sinking of the lift beyond a suitable depth in the water.
