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 designation PP stands for "Pontoon Park" and can be assembled into a group of rafts or a bridge spanning up to 879 ft (268 m) with a capacity from 90 to 360 tons. The system employs 15 ton Ural-53236 trucks and BMK-225 bridging boats. [5] The latest variant of the PP-91 system is the PP-2005 which uses KamAZ 63501 trucks and BMK-MT ...
A pontoon bridge (or ponton bridge), also known as a floating bridge, uses floats or shallow-draft boats to support a continuous deck for pedestrian and vehicle travel. The buoyancy of the supports limits the maximum load that they can carry. Most pontoon bridges are temporary and used in wartime and civil emergencies.
A graphical representation of the dimensions used to describe a ship. f is the freeboard.. In sailing and boating, a vessel's freeboard is the distance from the waterline to the upper deck level, measured at the lowest point of sheer where water can enter the boat or ship. [1]

This pontoon had three longitudinal bulkheads and six transverse bulkheads, dividing it in 28 compartments. Thickness of these bulkheads was 10–13 mm. [2] The weight of the dock was 2,126,472 kg The water would be pumped out of the pontoon by two steam engines situated at the height of the second walkway.
For amphibious operation, two large aluminium pontoons are deployed, unfolding them along the length of its hull. The crew exits the vehicle cab to maneuver the pontoon using controls located on top of the hull. In water, the M3 is propelled at speeds of up to 14 km/h (8.7 mph) by two pump jets that can be steered in 360-degrees. [3]
