Esse 990
The Esse 990 is a 9.9 meter long racing sportboat designed by Umberto Feland built by Josef Schuchter Sportboats of Stafa, Switzerla The first hull was sold in 2008 and series production was begun in 2009. The design is an outgrowth of the success of the Esse 850 which had over 110 boats in the one-design fleet by mid-2009. The design is a very powerful sportboat capable of being raced as a daysailer or as an IMS rated coastal racer. It is a very high performance sportboat designed to be raced with a crew of 4 sailors. The design also includes a self-tacking jib to ease handling. Auxiliary propulsion is provided by a saildrive. The design is characterized by a large ballast to displacement ratio and a relatively narrow hull of 2.55 meters beam and a tall mast with a high aspect ratio sail plan. In concert with most sportboats, the Esse 990 is designed as an alternative to the complexity of traditional sloop-rigged sailboats, with an emphasis on ease of handling with a small crew ...

Esse 850
The Esse 850 is an 8.5 metre long racing sportboat designed by Umberto Felcand built by Josef Schuchter Sportboats of Stafa, Switzerlan The first hull was sold in 2004 and the Esse 850 International Class Association was begun in 2005 in Europe. The design has achieved some popularity in Europe with over 110 boats in the one-design fleet by mid-2009. The design is unusual in that it is a very high performance sportboat designed to be raced with a crew of 1-4 sailors. Class rules established by Esse 850 International Class have a maximum crew weight of 280 kilos which effectively limits the crew to 3 athletic adults. The design is characterized by a very large ballast to displacement ratio and a narrow hull of 2.2 metres Beam (nautical), beam and a tall mast with a high aspect ratio sail plan. In concert with most sportboats, the Esse 850 is designed as an alternative to the complexity of traditional sloop-rigged sailboats, with an emphasis on ease of handling with a small crew and ...

Sportboat
The term sportsboat first appeared in the late 1980s and early 1990s to describe trailer sailers that were optimised for high performance at the expense of accommodation and ballast. The very definition of the term "sportsboat" is evolving. There is an absence of an accepted definition of the term. They tend to be characterised by historically large sail areas for a given length (especially under downwind sails), light weight construction and a heavy reliance on crew weight to counterbalance heeling forces. They usually feature lifting keels (for easy trailerability) of a modern fin and bulb design and planing hull designs. Most sportsboats are self-righting as opposed to skiffs. As similar design philosophies spread into larger classes the length of most sportsboats has come to be considered as between 5.5m and 8m (18'-26'). Boats of a similar design but of larger size have come to be known as sports yachts and are generally in the size range of 9m - 12m. Their noncomformity ...

International Measurement System
The International Measurement System (IMS) is a system of handicapping sailboats for the purpose of racing that replaced the earlier International Offshore Rule (IOR) system in the early 1990s. It is managed by the Offshore Racing Congress (ORC). In the sailing world it is usually referred to simply as 'IMS'. Synopsis IMS was the first yacht racing rule developed around the central idea of a Velocity prediction program (VPP). The VPP was a complex computer program that integrated continuous hullform information in order to predict a given boat's speed potential in a given wind velocity. Details on the VPP were openly available to the yachting community, in contrast to the earlier IOR system. Designers and boat owners much preferred this as they were able to design new yachts to maximise performance under the rule with a degree of certainty they had not enjoyed under the IOR rule. IMS is generally believed to have made significant leaps of progress forward from the IOR rule it di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Epoxy
Epoxy is the family of basic components or cured end products of epoxy resins. Epoxy resins, also known as polyepoxides, are a class of reactive prepolymers and polymers which contain epoxide groups. The epoxide functional group is also collectively called ''epoxy''. The IUPAC name for an epoxide group is an oxirane. Epoxy resins may be reacted (cross-linked) either with themselves through catalytic homopolymerisation, or with a wide range of co-reactants including polyfunctional amines, acids (and acid anhydrides), phenols, alcohols and thiols (usually called mercaptans). These co-reactants are often referred to as hardeners or curatives, and the cross-linking reaction is commonly referred to as curing. Reaction of polyepoxides with themselves or with polyfunctional hardeners forms a thermosetting polymer, often with favorable mechanical properties and high thermal and chemical resistance. Epoxy has a wide range of applications, including metal coatings, composites, use in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Composite Materials
A composite material (also called a composition material or shortened to composite, which is the common name) is a material which is produced from two or more constituent materials. These constituent materials have notably dissimilar chemical or physical properties and are merged to create a material with properties unlike the individual elements. Within the finished structure, the individual elements remain separate and distinct, distinguishing composites from mixtures and solid solutions. Typical engineered composite materials include: * Reinforced concrete and masonry *Composite wood such as plywood *Reinforced plastics, such as fibre-reinforced polymer or fiberglass *Ceramic matrix composites ( composite ceramic and metal matrices) *Metal matrix composites *and other advanced composite materials There are various reasons where new material can be favoured. Typical examples include materials which are less expensive, lighter, stronger or more durable when compared with com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carbon Fiber
Carbon fiber-reinforced polymers (American English), carbon-fibre-reinforced polymers (Commonwealth English), carbon-fiber-reinforced plastics, carbon-fiber reinforced-thermoplastic (CFRP, CRP, CFRTP), also known as carbon fiber, carbon composite, or just carbon, are extremely strong and light fiber-reinforced plastics that contain carbon fibers. CFRPs can be expensive to produce, but are commonly used wherever high strength-to-weight ratio and stiffness (rigidity) are required, such as aerospace, superstructures of ships, automotive, civil engineering, sports equipment, and an increasing number of consumer and technical applications. The binding polymer is often a thermoset resin such as epoxy, but other thermoset or thermoplastic polymers, such as polyester, vinyl ester, or nylon, are sometimes used. The properties of the final CFRP product can be affected by the type of additives introduced to the binding matrix (resin). The most common additive is silica, but other addi ...

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 'fractional rig' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gennaker
A gennaker is a sail that was developed around 1990. 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 boats to bridge the performance gap between a genoa and a spinnaker. It is sometimes the only downwind sail on board because it is easier to use and less expensive than a spinnaker. Due to its geometry, the sail is less prone to collapsing than a spinnaker. A gennaker is optimal for a beam reach, while an asymmetrical spinnaker is optimal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Keelboats
A keelboat is a riverine cargo-capable working boat, or a small- to mid-sized recreational sailing yacht. The boats in the first category have shallow structural keels, and are nearly flat-bottomed and often used leeboards if forced in open water, while modern recreational keelboats have prominent fixed fin keels, and considerable draft. The two terms may draw from cognate words with different final meaning. A keep boat, keelboat, or keel-boat is a type of usually long, narrow cigar-shaped riverboat, or unsheltered water barge which is sometimes also called a poleboat—that is built about a slight keel and is designed as a boat built for the navigation of rivers, shallow lakes, and sometimes canals that were commonly used in America including use in great numbers by settlers making their way west in the century-plus of wide-open western American frontiers. They were also used extensively for transporting cargo to market, and for exploration and trading expeditions, for wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
