Pontoons are flat, buoyant structures used to support various types of floating platforms, such as boats or bridges. They are typically made from materials like aluminum, fiberglass, or plastic, which help them stay afloat. Pontoons can be found in many applications, including recreational boats, floating docks, and even temporary bridges. These structures work by displacing water, which creates buoyancy. The design of pontoons allows them to provide stability and support for the objects they carry. They are essential in marine environments, enabling activities like fishing, water sports, and transportation across bodies of water.
