Yacht lengths normally range from 30 ft up to hundreds of feet. A luxury craft smaller than 39 ft is more commonly called a cabin cruiser or simply a cruiser. Motor yachts typically have one or two internal combustion engines that burn diesel fuel or gasoline.
The shape of a motor yacht’s hull may be based on displacement, planing, or in between. Although monohulls have long been the standard in motor yachts, multihulls are gaining in popularity.
