A Bermuda rig, Bermudian rig, or Marconi rig is a configuration of mast and rigging for a type of sailboat and is the typical configuration for most modern sailboats. This configuration was developed in Bermuda in the 1600s; the term Marconi, a reference to the inventor of the radio, Guglielmo Marconi, became associated with this configuration in the early 1900s because the wires that stabilize the mast of a Bermuda rig reminded observers of the wires on early radio masts. Description The rig consists of a triangular sail set aft of the mast with its mainsail raised to the top of the mast; its luff runs down the mast and is normally attached to it for its entire length; its tack is attached at the base of the mast; its foot (in modern versions of the rig) controlled by a boom; and its clew attached to the aft end of the boom, which is controlled by its sheet. Originally developed for smaller Bermudian vessels, and ultimately adapted to the larger, ocean-going Bermuda sloop, the Bermuda sail is set as the mainsail on the main mast. The Bermuda rigging has largely replaced the older gaff rigged fore-and-aft sails, except notably on schooners. The traditional design as developed in Bermuda features very tall, raked masts, a long bowsprit, and may or may not have a boom. In some configurations such as the Bermuda Fitted Dinghy vast areas of sail are achieved with this rig. Elsewhere, however, the design has omitted the bowsprit, and has otherwise become less extreme. A Bermuda rigged sloop with a single jib is known as a Bermuda sloop, a Marconi sloop, or a Marconi rig. A Bermuda sloop may also be a more specific type of vessel such as a small sailing ships traditional in Bermuda which may or may not be Bermuda rigged. The foot of a Bermuda sail may be attached to the boom along its length, or in some modern rigs the sail is attached to the boom only at its ends. This modern variation of a Bermuda mainsail is known as a loose-footed main. In some early Bermudian vessels, the mainsails were attached only to the mast and deck, lacking booms. This is the case on two of the three masts of the newly built Spirit of Bermuda, a replica of an 1830s British Royal Navy sloop-of-war. Additional sails were also often mounted on
