a relatively small watercraft propelled by an internal-combustion or electric engine. Motorboats range in size from miniature craft designed to carry one person to seagoing vessels of 100 feet (30 m) or more. Most motorboats, however, have space for six passengers or fewer. Motorboats are used recreationally for traveling on water (cruising) and for the enjoyment of such sports as fishing, duck hunting, swimming, skin diving, and water skiing. In sport they are used for racing and in piloting and navigation contests.
