Pontoon Boats

5058626544 A pontoon boat is a flattish boat that relies on pontoons to float. These pontoons (also called tubes) contain a lot of reserve buoyancy and allow designers to create massive deck plans fitted with all sorts of accommodations, such as expansive lounge areas, stand-up bars, and sun pads. Better tube design has also allowed builders to put ever-increasing amounts of horsepower on the stern.[1] Pontoon boat drafts may be as shallow as eight inches, which reduces risk of running aground and underwater damage. The pontoon effect is when a large force applied to the side capsizes a pontoon boat without much warning, particularly a top-heavy boat. Common boat designs are a catamaran with two pontoons, or a trimaran with three. Boats with three pontoons are sometimes called tri-toons.
