Offshore cruising mainsails sometimes have a hollow leech (the inverse of a roach) to obviate the need for battens and their ensuing likelihood of chafing the sail. [12] Roach is a term also applied to square sail design—it is the arc of a circle above a straight line from clew to clew at the foot of a square sail, from which sail material is ...
Historical fore-and-aft rigs used a four-sided gaff rigged mainsail, sometimes setting a gaff topsail above it. Whereas once the mainsail was typically the largest sail, today the mainsail may be smaller than the jib or genoa; Prout catamarans typically have a mainmast stepped further aft than in a standard sloop, so that the mainsail is much ...
Offshore cruising mainsails sometimes have a hollow leech (the inverse of a roach) to obviate the need for battens and their ensuing likelihood of chafing the sail. [40] The roach on a square sail design is the arc of a circle above a straight line from clew to clew at the foot of a square sail, which allows the foot of the sail to clear stays ...
Many mast-aft rigs utilize a small mainsail and multiple staysails that can resemble some cutter rigs. A cutter is a single masted vessel, differentiated from a sloop either by the number of staysails, with a sloop having one and a cutter more than one, or by the position of the mast, with a cutter's mast being located between 50% and 70% of the way from the aft to the front of the sailplan ...
[2] [3] Eastern lug sail, which used battens and is commonly known as "junk rig", was likely not Chinese in origin: The oldest depiction of a battened junk sail comes from the Bayon temple at Angkor Thom, Cambodia. [4]: 460–461 From its characteristics and location, it is likely that the ship depicted in Bayon was a Southeast Asian ship.
Lewis R. French, a gaff-rigged schooner Oosterschelde, a topsail schooner Orianda, a staysail schooner, with Bermuda mainsail. A schooner (/ ˈ s k uː n ər / SKOO-nər) [1] is a type of sailing vessel defined by its rig: fore-and-aft rigged on all of two or more masts and, in the case of a two-masted schooner, the foremast generally being shorter than the mainmast.
By the 1800s, the design of Bermudian vessels had largely dispensed with square topsails and gaff rig, replacing them with triangular main sails and jibs. The Bermuda rig had traditionally been used on vessels with two or more masts, with the gaff rig favoured for single-masted vessels.
The idea for a furling jib is usually attributed to Major E du Boulay in England who invented a device similar to a roller blind for reefing a jib [citation needed].Major Wykeham-Martin used one of Boulay's rollers and improved the system by incorporating roller bearings in 1907 when the system was patented.
