Abstract
A water-ski towline winch assembly comprises a support member adapted to be mounted on a boat and an annular drum rotatably mounted on the support member. A handle is rotatably mounted on the support member to rotate the drum to selectively reel-in or reel-out the towline, via a stepped-down gear set. A plurality of slots are formed in the drum whereby floats secured on the towline may be positioned exteriorly of the drum in non-interfering relationship with the towline which is wrapped on the drum. A release mechanism is provided for permitting the gear set to free-wheel to troll out the towline. Two embodiments of the invention are disclosed herein with one of the embodiments (FIGS. 7-11) including a mounting bracket for vertical or horizontal securance to the hull of the boat and a support bracket attachable to the mounting bracket and having the winch assembly proper mounted thereon.
