Is it a floating platform for lake boat docking?
Not exactly, but close! Rather than having a floating platform, pneumatic lake lifts use bunk boards. Bunk boards are like runners that span the full length of a boat. The vessel comes to rest on the bunks as air fills the flotation tanks and they rise up from beneath the boat. However, we do have PWC lifts for sale that are very much like a Jet Ski floating platform.
