ABSTRACT:
The invention concerns a boat hull support that includes a pair of hull support members spaced from each other and each pivotally mounted intermediate its ends to spaced uprights. A guide post is mounted for vertical movement in the space between the support members, and sliding rods join the support members to the guide post so that vertical movement of the guide post will be translated into substantially equal movement of the support members about their pivots.
