Genoa (sail)
A genoa sail is a type of large jib or staysail that extends past the mast and so overlaps the main sail when viewed from the side, sometimes eliminating it. It was originally called an "overlapping jib" and later a genoa jib. It is used on single-masted sloops and twin-masted boats such as yawls and ketches. Its larger surface area increases the speed of the craft in light to moderate winds; in high wind, a smaller jib is usually substituted, and downwind a spinnaker may be used. Definition The term ''jib'' is the generic term for any of an assortment of ''headsails''. The term ''genoa'' (or genny) refers to a type of jib that is larger than 100% of the foretriangle, which is the triangular area formed by the point at which the stay intersects the mast (sailing), mast, and deck (ship), deck or bowsprit, and the line where the mast (sailing), mast intersects deck (ship), deck at the rail. Colloquially the term is sometimes used interchangeably with ''jib''. A working jib is no la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

PHRF
Performance Handicap Racing Fleet (PHRF) is a handicapping system used for yacht racing in North America. It allows dissimilar classes of sailboats to be raced against each other. The aim is to cancel out the inherent advantages and disadvantages of each class of boats, so that results reflect crew skill rather than equipment superiority. PHRF is used mainly for larger sailboats (i.e., 7 meters and above). For dinghy racing, the Portsmouth yardstick handicapping system is more likely to be used. The handicap number assigned to a class of yachts is based on the yacht's speed relative to a theoretical yacht with a rating of 0. A yacht's handicap, or rating, is the number of seconds per mile traveled that the yacht in question should be behind the theoretical yacht. Most boats have a positive PHRF rating, but some very fast boats have a negative PHRF rating. If Boat A has a PHRF rating of 15 and Boat B has a rating of 30 and they compete on a 1 mile course, Boat A should finish ...

Genoa
Genoa ( ; ; ) is a city in and the capital of the Italian region of Liguria, and the sixth-largest city in Italy. As of 2025, 563,947 people live within the city's administrative limits. While its metropolitan city has 818,651 inhabitants, more than 1.5 million people live in the wider metropolitan area stretching along the Italian Riviera. On the Gulf of Genoa in the Ligurian Sea, Genoa has historically been one of the most important ports on the Mediterranean: it is the busiest city in Italy and in the Mediterranean Sea and twelfth-busiest in the European Union. Genoa was the capital of one of the most powerful maritime republics for over seven centuries, from the 11th century to 1797. Particularly from the 12th century to the 15th century, the city played a leading role in the history of commerce and trade in Europe, becoming one of the largest naval powers of the continent and considered among the wealthiest cities in the world. It was also nicknamed ''la S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Sven Salén
Sven Gustaf Salén (7 November 1890 – 29 October 1969) was a Swedish sailor who competed in the 1936 and 1952 Summer Olympics. In 1936, together with his wife Dagmar Salén, he won a bronze medal in the mixed 6 m class as the helmsman of the boat ''May Be''. Sixteen years later he finished fourth as the helmsman of the boat ''May Be VII'' in the same event. Between 1922 and 1962 Salén ran his company Salén Lines. He was first to use an oversized foresail on his 6 meter racing yacht "May-Be" in the 1926 race Coppa del Tirreno in Genoa. This is why this sail is called a genoa. He successfully used it during the Scandinavian Gold Cup’s races of 1927 in Oyster Bay (US). Sven Salén also pioneered the parachute spinnaker. His sailing career was boosted after his team won the 6 m event at the unofficial world championships in 1927. In 1927 he received the Svenska Dagbladet Gold Medal. Salén was also a singer-songwriter and a founder, with Ulf Peder Olrog, of the Sw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Points Of Sail
A point of sail is a sailing craft's Course (navigation), direction of travel under sail in relation to the true wind direction over the surface. The principal points of sail roughly correspond to 45° segments of a circle, starting with 0° directly into the wind. For many sailing craft 45° on either side of the wind is a ''no-go'' zone, where a sail is unable to mobilize power from the wind. Sailing on a course as close to the wind as possible—approximately 45°—is termed ''beating'', a point of sail when the sails are ''close-hauled''. At 90° off the wind, a craft is on a ''beam reach''. The point of sail between beating and a beam reach is called a ''close reach''. At 135° off the wind, a craft is on a ''broad reach''. At 180° off the wind (sailing in the same direction as the wind), a craft is ''running downwind''. A given point of sail (beating, close reach, beam reach, broad reach, and running downwind) is defined in reference to the #True wind versus apparent win ...

Camber (aerodynamics)
In aeronautics and aeronautical engineering, camber is the asymmetry between the two acting surfaces of an airfoil, with the top surface of a wing (or correspondingly the front surface of a propeller blade) commonly being more convex (positive camber). An airfoil that is not cambered is called a ''symmetric airfoil''. The benefits of cambering were discovered and first utilized by George Cayley in the early 19th century. Overview Camber is usually designed into an airfoil to raise its maximum lift coefficient CLmax. This minimizes the Stall (flight), stalling speed of aircraft using the airfoil. An aircraft with wings using a cambered airfoil will have a lower stalling speed than an aircraft with a similar wing loading and wings using a symmetric airfoil. One recent cambered design is called the supercritical airfoil. It is used for near-supersonic flight and produces a higher lift-to-drag ratio at near supersonic flight than traditional airfoils. Supercritical airfoils employ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
North Sails
North Sails is an international sailmaker and sailing wear company with operations in 29 countries. The company designs, engineers and manufactures sails for sailboat racing, racing and cruising sailboats from 8 feet (2.5m) to more-than 200 feet (60m) in length.

History North Sails was founded in 1957 by Lowell North, in San Diego, California, San Diego, California. An engineer by training, North applied a rigorous, methodical approach to designing sails, with the goal of building sails that were faster than the competition’s. North began testing the strength and stretch characteristics of sailcloth he received from his suppliers, to eliminate variability in his raw materials. He introduced computer-driven laser cutting ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Brand Name
A brand is a name, term, design, symbol or any other feature that distinguishes one seller's goods or service from those of other sellers. Brands are used in business, marketing, and advertising for recognition and, importantly, to create and store value as brand equity for the object identified, to the benefit of the brand's customers, its owners and shareholders. Brand names are sometimes distinguished from Generic brand, generic or store brands. The practice of branding—in the original literal sense of marking by burning—is thought to have begun with the ancient Egyptians, who are known to have engaged in livestock branding and branded slaves as early as 2,700 BCE. Branding was used to differentiate one person's cattle from another's by means of a distinctive symbol burned into the animal's skin with a hot branding iron. If a person stole any of the cattle, anyone else who saw the symbol could deduce the actual owner. The term has been extended to mean a strategic person ...

Gennaker
A gennaker is a sail that was developed before the 1980s. Used when sailing downwind, it is a cross between a genoa and a spinnaker. It is not symmetric like a true spinnaker but is asymmetric like a genoa, but the gennaker is not attached to the forestay like a jib or genoa. The gennaker is rigged like a spinnaker but the tack is fastened to the hull or to a bowsprit. It has greater camber than a genoa (but significantly less camber than a spinnaker). This is optimal for generating lift at larger angles of attack. An early form of gennaker was the "gollywhomper", used briefly in the 1870s. The gennaker is a specialty sail primarily used on racing In sports, racing is a competition of speed, in which competitors try to complete a given task in the shortest amount of time. Typically this involves traversing some distance, but it can be any other task involving speed to reach a specific g ... boats to bridge the performance gap between a genoa and a spinnaker. It is ...

Tack (maneuver)
Tacking or coming about is a sailing maneuver by which a sailing craft ( sailing vessel, ice boat, or land yacht), whose next destination is into the wind, turns its bow toward and through the wind so that the direction from which the wind blows changes from one side of the boat to the other, allowing progress in the desired direction. Sailing vessels are unable to sail higher than a certain angle towards the wind, so "beating to windward" in a zig-zag fashion with a series of tacking maneuvers, allows a vessel to sail towards a destination that is closer to the wind than the vessel can sail directly. A sailing craft whose course is downwind jibes (or "wears" if square-rigged) by having the apparent wind cross the stern from one tack to the other. High-performance sailing craft may tack, rather than jibe, downwind, when the apparent wind is well forward. Beating to windward Sails are limited in how close to the direction of the wind they can power a sailing craft. The are ...
