Bermuda rig

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 17th century; the term Marconi was a much later reference to the inventor Guglielmo Marconi whose wireless radio masts resembled the wires that stabilize the mast of a Bermuda rigged ship.

The rig consists of a triangular sail set aft of the mast with its head 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.
