s to remain buoyant. These pontoons (also called ''tubes'') contain much reserve buoyancy and allow designers to create large deck plans fitted with a variety of accommodations including expansive lounge areas, stand-up bars, and sun pads. Better tube designs have allowed builders to put ever-increasing amounts of horsepower on the stern. Pontoon boat drafts may be as shallow as eight inches (20 centimetres), which reduces risk of running aground and underwater damage, this allows it to come close to shore to pick up and drop off loads.

. Ambrose Weeres put a wooden platform on two columns of steel barrels welded together end-to-end, creating a sturdy deck that would be more stable on a lake than a conventional boat. Living in the "Land of 10,000 Lakes", Weeres thought this idea might be marketed. The first boat was "The Empress". He built a few boats and sold them with the help of dealers. He started Weeres Industries to meet unexpected demand. Weeres, later called "Mr. Pontoon", was elected to the Minnesota Marina Hall of Fame.
