A speedboat is a type of small, fast boat that is designed to be powered by an engine. It typically has a long and slender hull, with a flat bottom and V-shaped sides, which allows it to slice through the water efficiently at high speeds. Speedboats are commonly used for recreational activities such as water skiing or wakeboarding, but they can also be used for transportation or fishing. They usually have a small cabin or open deck area where passengers can sit and enjoy the ride.
