<p>A plurality of support vertical extensions (25) are attached to the rear surface or transom (14) of a boat (15), or to a dock. Each support vertical extension has a horizontal member (60) so that a dinghy or the like can be supported transversely to the boat or dock. The vertical extensions (25), and thus the horizontal members (60), are raised and lowered by at least one hydraulic cylinder (30) driving each of the vertical extensions (25). The vertical extensions (25) are preferably telescoping into fixed vertical support members (20).</p> |
