Pontoon boats are some of the most popular recreational vessels around, especially for people who love to hit the water for some leisurely boating. One of the key features of pontoon boats is the pontoons themselves, which are the cylindrical or rectangular floatation devices that support the boat in the water. But have you ever wondered what’s actually inside these pontoons? Here’s a closer look at the anatomy of a pontoon boat.
The first thing to understand is that there are two types of pontoon boats: aluminum and fiberglass. The way the pontoons are constructed differs between these types of boats. So, let’s take a look at each one.
Aluminum Pontoons
Aluminum pontoons are constructed of two or three cylindrical tubes that run the length of the boat. These tubes are made of aluminum and are sealed on each end. Inside each tube, there is air which provides the buoyancy required to keep the boat afloat. But there is typically more than just air in these pontoons. For example, some manufacturers will add foam or other materials to help dampen sound and vibration while enhancing the boat’s overall performance.
Additionally, aluminum pontoons also contain various chambers and compartments. These are used for a variety of purposes, including storage space, fuel storage, and water tanks. In larger pontoon boats, some of these compartments may be used for auxiliary sleeping quarters or additional entertainment areas.
Fiberglass Pontoons
Fiberglass pontoons are a bit different from aluminum pontoons. They are typically made of two fiberglass shells that are sealed together. The shells, in turn, are filled with closed-cell foam, which provides the required buoyancy. The foam is also great for minimizing noise and vibrations that can be generated by the boat’s engine or other equipment.
Fiberglass pontoons don’t typically have any chambers or compartments like aluminum pontoons. There are no additional storage areas or fuel storage within the pontoons themselves. However, fiberglass pontoons can still have plenty of storage space above the waterline, and some boats may also have aft and bow compartments.
Final Thoughts
Pontoon boats are designed to offer a comfortable and stable boating experience. Knowing what’s inside the pontoons can help you understand some of the factors that contribute to that comfort and stability. Whether it’s foam or additional compartments, these elements all play a role in making your pontoon boat ride enjoyable. If you’re in the market for a pontoon boat, be sure to do your research to find the one that is the best fit for your needs.
