A motorboat, also known as a speedboat or powerboat, is a marine vessel that is powered by an engine. In 1886, the earliest boat powered by a petrol engine was made by Gottlieb Daimler and Wilhelm Maybach. Motorboats have an inboard engine or an outboard motor on the rear of the boat that contains the internal combustion engine, gearbox, and the propeller in one unit. Some motor boats have a hybrid-inboard-outboard engine. Powerboats vary in size and shape, but they all have a bow (the front), stern (the back), hull (the bottom), and topsides (from the hull up). The most common types of power boats are the bass boat, bay boat, bow rider, cruiser, deck boat, jet boat, pontoon boat, and utility boat.
