Bermuda rig takes its name from Bermuda, where it was developed in the 17th century. The term Marconi, a reference to the inventor of the radio, Guglielmo Marconi, became associated with this configuration in the early 20th century, because the wires that stabilize the mast of a Bermuda rig reminded observers of the wires on early radio masts.

A mast-aft rig is a sailboat sail-plan that uses a single mast set in the aft half of the hull. The mast supports fore-sails that may consist of a single jib, multiple staysails, or a crab claw sail. The mainsail is either small or completely absent. Mast-aft rigs are uncommon, but are found on a few custom, and production sailboats. [1]
The modern Bermuda rig uses a triangular mainsail aft of the mast, closely coordinated with a jib for sailing upwind. A large overlapping jib or genoa is often larger than the mainsail. In downwind conditions (with the wind behind the boat) a spinnaker replaces the jib.
Fore-and-aft rig features sails that run fore and aft (along the length of the sailing craft), controlled by lines called "sheets", that changes sides, as the bow passes through the wind from one side of the craft to the other. Fore-and-aft rig variants include: Bermuda rig (also known as a Marconi rig) features a three-sided mainsail.
Part of the design of the B&R rig involves inducing a "pre-bend" in the mast which provides some of the side-to-side and fore-and-aft stability of the rig. [2] [3] [4] The pre-bend is achieved by tensioning the reverse diagonals and certain other so called intermediate shrouds. Because the spreaders are swept back at approximately a 25° to 30 ...

By either hauling or easing the line, the tension in the luff can be changed, thereby shifting the point of maximum draft of the sail forward or aft respectively, optimizing sail shape and thus performance. It is a fine control which is used more frequently on racing sailboats than on cruising or day-sailing boats.
In the simpler definition, the sailing rig called "cutter" has a single mast with fore and aft sails which include more than one headsail. The mainsail (set abaft, or behind the mast) could be gaff, Bermuda, standing lug or gunter rigged. A more complex definition may be applied in American waters, where a boat with two headsails would be ...
