A vessel of state or pleasure: the former is usually employed to convey great personages. One of the designs of a yacht being accommodation, they are usually fitted up with great comfort; their propulsion is by sails or steam. Small yachts, rigged as sloops, were formerly used by the commissioners of the navy; they were originally royal yachts, and one at Chatham was renowned as the yacht of Queen Elizabeth, the same plate being in use in her up to a very late date. Private pleasure-boats, when sufficiently large for a sea voyage, are also termed yachts. (See royal yacht.)
