I would like to launch my sunfish from the top of my bulkhead down to the water about 5 feet down. There are large boulders protecting my bulkhead from erosion. The water depth is about 3/4 feet. I am thinking of a pair of 2 by 6s covered with carpet plus a winch. I have a dock and could try and set up a lift system from the dock which is also an option. Has anyone had experience here? I would appreciate any advice. Thanks WBF
