A pneumatic boat top lift having pneumatic telescoping supports anchored to the deck and to the top of the boat. The number of telescoping supports for pontoon boats will typically be four. A single telescoping support will typically be used for knock down boat tops. Pressurized air is supplied to the telescoping supports by a pressurized air distribution system. The air pressure is raised and lowered respectively by a pressurized air control system, thereby raising and lowering the boat top.
