Masthead Sloop
A masthead rig on a sailing vessel consists of a forestay and backstay both attached at the top of the mast. The Bermuda rig can be split into two groups: the masthead rig and the fractional rig. The masthead rig has larger and more headsails, and a smaller mainsail, compared to the fractional rig. The major advantage a masthead sloop has over a fractional one, is that the jib is larger. Since the jib has no mast in front of it to cause turbulent airflow over it, it is considered much more efficient than the main, especially for sailing up wind. Also, since the fore stay is attached to the top of the mast, it pulls directly against the back stay. Tightening the back stay, then, increases the tension on the fore stay. This is useful because the jib needs considerable fore stay tension to set well. This need increases in direct proportion to the wind speed and jib size. Increasing the tension on the back stay does not tend to bend the mast, as it would on a fractional sloop. It pu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Forestay
On a sailing vessel, a forestay, sometimes just called a stay, is a piece of standing rigging which keeps a mast from falling backwards. It is attached either at the very top of the mast, or in fractional rigs between about 1/8 and 1/4 from the top of the mast. The other end of the forestay is attached to the bow of the boat. Often a sail is attached to the forestay. This sail may be a jib or a genoa. In a cutter rig, the jib or jibs are flown from stays in front of the forestay, perhaps going from the masthead to a bowsprit. The sail on the forestay is then referred to as the staysail or stays'l. A forestay might be made from stainless steel wire on a modern yacht, solid stainless steel rod, carbon rod, or ultra high molecular weight polyethylene (such as Spectra or Dyneema) on a high-performance racing boat, and galvanised wire or natural fibers on an older cutter or square-rigged ship.

Backstay
A backstay is a piece of standing rigging on a sailing vessel that runs from the mast to either its transom or rear quarter, counteracting the forestay and jib. It is an important sail trim control and has a direct effect on the shape of the mainsail and the headsail. Backstays are generally adjusted by block and tackle, hydraulic adjusters, or lines leading to winches. Types Backstays may be ''permanent'' or ''running''. Permanent backstay A permanent backstay is attached to the top of the mast. Running backstays appear in pairs attached about two-thirds of the way up the mast (sometimes at multiple locations along the length of the mast). In general, most modern sailboats have a permanent backstay and some have a permanent backstay combined with running backstays. Backstays are not always found on all vessels, especially smaller ones. A permanent backstay is attached at the top of the mast and may or may not be readily adjustable. In a masthead rig, tensioning the perma ...

Bermuda Rig
Bermuda rig, Bermudian rig, or Marconi rig is a type of sailing rig that uses a triangular sail set abaft (behind) the mast. It is the typical configuration for most modern sailboats. Whilst commonly seen in sloop-rigged vessels, Bermuda rig is used in a range of configurations, for instance, a cutter or a schooner (where it may be used in conjunction with gaff rigged sails on other masts), and several other types. 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. Description The rig consists of a triangular sail set abaft (behind) 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 u ...

Fractional Rig
A fractional rig on a sailing vessel consists of a foresail, such as a jib or genoa sail, that does not reach all the way to the top of the mast. The forestay is a wire that secures the mast to the front of the boat. With a fractional rig, the forestay is attached between about 1/8 and 1/4 of the length of the mast lower down, rather than being attached to the top of the mast as in a masthead rig. The foresail (jib or genoa) is then rigged to this stay. The mast is farther forward on the boat than on a masthead rig and so it has a larger mainsail. Masthead rigs are most common on larger keelboats or cruisers. A fractional rig is typically used on sailing dinghies and racing oriented keelboats, such as the J/24. Fractional rigs were introduced on race boats in order to allow more controllability of the surface of the mainsail and also less drag when sailing upwind. According to one manufacturer, "a key to making fast boats easier to sail than slow boats is the 'fraction ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Weathercock
A wind vane, weather vane, or weathercock is an instrument used for showing the direction of the wind. It is typically used as an architectural ornament to the highest point of a building. The word ''vane'' comes from the Old English word , meaning "flag". Although partly functional, wind vanes are generally decorative, often featuring the traditional cockerel design with letters indicating the points of the compass. Other common motifs include ships, arrows, and horses. Not all wind vanes have pointers. In a sufficiently strong wind, the head of the arrow or cockerel (or equivalent) will indicate the direction from which the wind is blowing. Wind vanes are also found on small wind turbines to keep the wind turbine pointing into the wind. History The oldest known textual references to weather vanes date from 1800-1600 BCE Babylon, where a fable called ''The Fable of the Willow'' describes people looking at a weather vane "for the direction of the wind." In China, the ''Hua ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cutter (boat)
A cutter is any of various types of watercraft. The term can refer to the sail plan, rig (sail plan) of a sailing vessel (but with regional differences in definition), to a governmental enforcement agency vessel (such as a coast guard or border force cutter), to a type of ship's boat which can be used under sail or oars, or, historically, to a type of fast-sailing vessel introduced in the 18th century, some of which were used as small warships. As a sailing rig, a cutter is a single-masted boat, with two or more headsails. On the eastern side of the Atlantic Ocean, Atlantic, the two headsails on a single mast is the fullest extent of the modern definition. In U.S. waters, a greater level of complexity applies, with the placement of the mast and the rigging details of the bowsprit taken into account so a boat with two headsails may be classed as a sloop. Government agencies use the term "cutter" for vessels employed in patrolling their territorial waters and other enforcement a ...

Fractional Rig
A fractional rig on a sailing vessel consists of a foresail, such as a jib or genoa sail, that does not reach all the way to the top of the mast. The forestay is a wire that secures the mast to the front of the boat. With a fractional rig, the forestay is attached between about 1/8 and 1/4 of the length of the mast lower down, rather than being attached to the top of the mast as in a masthead rig. The foresail (jib or genoa) is then rigged to this stay. The mast is farther forward on the boat than on a masthead rig and so it has a larger mainsail. Masthead rigs are most common on larger keelboats or cruisers. A fractional rig is typically used on sailing dinghies and racing oriented keelboats, such as the J/24.

Gaff Rig
Gaff rig is a sailing rig (configuration of sails, mast and stays) in which the sail is four-cornered, fore-and-aft rigged, controlled at its peak and, usually, its entire head by a spar (pole) called the ''gaff''. Because of the size and shape of the sail, a gaff rig will have running backstays rather than permanent backstays. The gaff enables a fore-and-aft sail to be four sided, rather than triangular. A gaff rig typically carries 25 percent more sail than an equivalent Bermuda rig for a given hull design. A sail hoisted from a gaff is called a gaff-rigged sail. Description Gaff rig remains the most popular fore-aft rig for schooner and barquentine mainsails and other course sails, and spanker sails on a square rigged vessel are always gaff rigged. On other rigs, particularly the sloop, ketch and yawl, gaff rigged sails were once common but have now been largely replaced by the Bermuda rig sail, which, in addition to being simpler than the gaff rig, usually all ...
