Last but certainly not least, aluminum pontoon boats are the most common type of pontoon boat on the market. The majority of major pontoon boat manufacturers make their pontoons using aluminum as well. Unlike steel, aluminum is non-corrosive, meaning that the pontoons wonât rust over time just from being exposed to moisture.
Pontoon boats have 2 or 3 aluminum tubes that support a broad platform. They have shallow drafts and are very stable. They are usually found on inland lakes and rivers and other small bodies of water. They are used for cruising, fishing and water sports.
