Frank, again specifics are needed, but quick opinions are; lighting should be no problem, just state requirements, use, etc. Several ways to go with boat lift, though not specifically familiar with them. I work on ship not small boat nav. and comm. equipment. How big is the boat? My 1st comment is have you thought about 2 manual winches, 1 on each end and crank up each side a little at a time? Anything can be done with enough mechanical advantage(gear ratio). AC or DC motors are an option. My first quick thought is a small gas generator for AC lift, a charger plugged in to it to charge batteries for a few minutes while lifting/lowering the boat would put a good quick boost to a deep cycle battery running some 12v lights.
Let me know what you want and I can offer a solution. Shop for AC and DC winch/lift, give me it's electrical requirements and I will present options.
