Multi-hull powerboats are generally referred to as "power catamarans” because most of these designs ride on two hull. You may find a power trimaran with three hulls, but they’re rare. Technically, pontoon boats, which are open deck boats built on twin metal flotation tubes are also multi-hull powerboats and pontoon boats with three tubes are called "tri-toons”.
Power cats have become extremely popular in recent years for multiple reasons: they offer more deck and cabin space than a monohull powerboat of the same length, they tend to be more fuel efficient since they don’t drag heavy ballast through the water, they’re very maneuverable since their engines are set wide apart eliminating the need for a bow thruster (a propeller that provides side thrust and therefore maneuvering control), they’re very stable at rest so you can get a good night’s sleep in a rolly anchorage, and often people feel less seasick on multi-hulls because they have a different motion on rough water.
