Build the dock that floats. You may also consider adding a 10hp motor
to it. Register it with the local government as a homemade boat. There
was an article in Adirondack Life a while back about this. Many
residents of Star Lake, I believe, built such "docks/boats" and would
meet together at the middle of the lake for get-togethers. Pretty cool
article. Pretty wild "docks." Two-level, seats 15 people,
slide-equipped, gas grills and even a head.
