Pontoon Floatation
The most common floatation device used in boats, docks, seaplanes, and hydrobike equipment are pontoons. A pontoon is designed to have enough buoyancy to carry a heavy load in water. Pontoons normally have a slim and lengthy design and are constructed of various materials including wood barrels, foam, or air-filled polyester and nylon (Figure 3). The benefit of pontoons is that they submerge to very shallow depths, which reduces the risk of colliding with rocks and other damaging obstructions.
