A pontoon boat is a type of watercraft that uses buoyant structures, called pontoons, to stay afloat. These pontoons are typically cylindrical and can be made from materials like aluminum or fiberglass. Pontoon boats are popular for recreational activities such as fishing, cruising, and entertaining due to their spacious decks and stability on the water. These boats often come equipped with comfortable seating, storage areas, and sometimes even amenities like kitchens or bathrooms. Their flat-bottom design allows for easy access to shallow waters, making them ideal for lakes and rivers. Overall, pontoon boats offer a versatile and enjoyable boating experience.
