A motorboat is a small, powered watercraft that uses an internal combustion engine to propel itself through the water. It typically has a flat bottom hull and a deck, with a single outboard motor or inboard engine driving a propeller at the rear of the boat. Motorboats can vary greatly in size and design, from small inflatable dinghies to larger, more luxurious vessels. They are often used for recreational purposes such as fishing, water skiing, or simply cruising on lakes, rivers, or coastal waters.
