A pontoon boat is a flattish boat that relies on nautical floats for buoyancy. Common boat designs are a catamaran with two pontoons, or a trimaran with three. [2] In many parts of the world, pontoon boats are used as small vehicle ferries to cross rivers and lakes. [3] An anchored raft-like platform used for diving, often referred to as a pontoon

A pleasure boat with two lengthwise pontoons. A pontoon boat is a flattish boat that relies on floats 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.
The hull number visible on both sides of the bow of USS Arleigh Burke, DDG-51. A hull number is a serial identification number given to a boat or ship. For the military, a lower number implies an older vessel. For civilian use, the Hull Identification Number (HIN) is used to trace the boat's history. The precise usage varies by country and type.
Hand operated longlining can be operated from boats of any size. The number of hooks and lines handled depends on the size of vessel, the number of crew, and the level of mechanisation. Large purpose built longliners can be designed for single species fisheries such as tuna. On such larger vessels the bridge is usually placed aft, and the gear ...
The pontoon-type VLFS platform rests on the water surface and is intended for deployment in calm waters such as a cove, a lagoon or a harbor. Its basic element is a simple box structure; it usually offers high stability, low manufacturing cost and easy maintenance and repair. The pontoon type is supported by its buoyancy on the sea surface.
Black pontoons on the wingtips of A-1 slanted diagonally backward toward the water to reduce friction on water and serve to balance aircraft on water. On the bottom of each pontoon is a little hydroplane of wood measuring 3-inch wide (76 mm) by 1 ⁄ 4-inch thick (6.4 mm) to further aid in balance and reduce friction. The front elevator on A-1 ...
