Pontoon boats have become increasingly popular over the years due to their stability, spaciousness, and versatility. These boats are ideal for a variety of activities including fishing, water skiing, and simply cruising on the water with friends and family. At the heart of every pontoon boat is a set of pontoons, which are the cylindrical objects that give the boat its unique shape and buoyancy.
So, what exactly are these pontoon tubes filled with? The answer is air. Most pontoons are made of aluminum or steel, and they are airtight structures that are sealed on both ends. The tubes are then filled with air, which provides the buoyancy necessary to keep the boat afloat. The amount of air that is pumped into the tubes will vary depending on the size and weight of the boat, as well as the number of passengers and the amount of gear onboard.
In addition to air, some manufacturers also fill the pontoon tubes with foam. This foam, which is typically made of polyurethane, is used to increase the overall strength and stiffness of the pontoons. It is a popular option for those who want the added reliability and durability that comes with foam-filled pontoons.
There are also some newer pontoon boats that are filled with water instead of air. These are known as “wet” or “submerged” pontoons and are becoming increasingly popular as they offer a smoother ride and better stability in rough water. Water-filled pontoons also help to reduce the effects of wind and waves, making it easier to maintain control of the boat in different conditions.
Overall, the answer to, is that they are mainly filled with air, but some manufacturers do add foam to increase strength and stiffness. There are also newer options available, such as water-filled pontoons, that offer additional benefits for boating enthusiasts. So, whether you are an avid fisherman, a water sports enthusiast, or simply love cruising on the water with friends and family, pontoon boats are a versatile and reliable option that will give you years of enjoyment on the water.
