Anyone here launch their ski from a pier or bulkhead? Looking for ideas for maybe a ramp system with hand winch to get ski's in and out of the water, where the water level is approximately 3' lower than pier height. Would prefer system that can be removed so there isn't anything that stays in the water (salt water). Thinking about a ski dolly with winch connected to rails, but figured someone here might have already (been there, done that). Thanks.
