It is a geometry-stabilized craft, deriving its stability from its wide beamrather than from a ballasted keel as with a monohull boat. Catamarans typically have less hull volume, smaller displacement, and shallower draft draught than monohulls of comparable length.

The two hulls combined also often have a smaller hydrodynamic resistance than comparable monohulls, requiring less propulsive catamaran sailboat manufacturers list data from either sails or motors. Catamaran sailboat manufacturers list data catamaran's wider stance on the water can reduce both heeling and wave-induced motion, as compared with a monohull, and can give reduced wakes.

Catamarans were invented by the Austronesian peoples which enabled their expansion to the islands of the Indian and Pacific Oceans. Catamaran sailboat manufacturers list data from Oceania and Maritime Southeast Asia became the inspiration for modern catamarans.

Until the 20th century catamaran development focused primarily on sail-driven concepts. However, the original kattumaram did not refer to double-hulled boats at all, catamaran sailboat manufacturers list data to a type of single-hulled raft of the Tamil people made of three to seven tree trunks lashed. The term has evolved in English usage to refer solely to catamaran sailboat manufacturers list data double-hulled boats.

Catamaran-type vessels were catamaran sailboat manufacturers list data early technology of the Austronesian peoples. Early researchers like Heine-Geldern and Hornell once believed that catamarans evolved from outrigger canoesbut modern authors specializing in Austronesian cultures like Doran and Mahdi now believe it to be the opposite.

Two canoes bound together developed directly from minimal raft technologies of two logs tied. Over time, the double-hulled canoe form developed into the asymmetric double canoe, where one hull is smaller than the. Eventually the smaller hull became the prototype outriggergiving way to the single outrigger canoe, then to the reversible single outrigger canoe. Finally, the single outrigger types developed into the double outrigger canoe or trimarans.

This would also explain why older Austronesian populations in Island Southeast Asia tend to favor double outrigger canoes, as it keeps the boats stable when tacking. But they still have small regions where catamarans and single-outrigger canoes are still used.

In contrast, more distant outlying descendant populations in OceaniaMadagascarand the Comorosretained the double-hull and the single outrigger canoe types, but the technology for double outriggers never reached them although it exists in western Melanesia. To deal with the problem of the instability of the boat when the outrigger faces leeward when tacking, they instead developed the shunting technique in sailing, in conjunction with reversible single-outriggers.

Despite their being the more "primitive form" of outrigger canoes, they were nonetheless effective, allowing seafaring Polynesians to voyage to distant Pacific islands.

The first documented example of double-hulled sailing craft in Europe was designed by William Petty in to sail faster, in shallower waters, in lighter wind, and with fewer crew than other vessels of the time. However, the unusual design met with skepticism and was not a commercial success.

The design remained relatively unused in the West for almost years until the early 19th-century, when the Englishman Mayflower F. Crisp built a two-hulled merchant ship in Rangoon, Burma. The ship was christened Original. Crisp described it as "a fast sailing fine sea boat; she traded during the monsoon between Rangoon and the Tenasserim Provinces for several years".

Later that century, the Catamaran sailboat manufacturers list data Nathanael Herreshoff constructed a double-hulled sailing boat of his own design US Pat.

Her debut demonstrated the distinct performance advantages afforded to catamarans over the standard monohulls. It was as catamaran sailboat manufacturers list data result of this event, the Centennial Regatta of the New York Yacht Club, that catamarans were barred from regular sailing classes, and this remained the case until the s. InEric de Bisschop built a Polynesian "double canoe" in Hawaii and sailed it home to a hero's welcome in France.

Inhe published his experiences in a book, Kaimiloawhich was translated into English in Roland and Francis Prout experimented with catamarans in and converted their boat factory in Canvey IslandEssex Englandto catamaran production in Their Shearwater catamarans easily won races against monohulls. In the mid-twentieth century, beachcats became a widespread category of sailing catamarans, owing to their ease of launching and mass production.

In California, a maker of surfboardsHobie Alterproduced the pound kg Hobie 14 inand two years later the larger and even more successful Hobie As ofthe Hobie 16 was still being produced with more thanhaving been manufactured. Catamarans were introduced to Olympic sailing in The two-handed Tornado catamaran was selected for the multihull discipline in the Olympic Games from through It was redesigned in Australia became the site of builders of large transport catamarans� Incat in [32] catamaran sailboat manufacturers list data Austal in [33] �each building civilian ferries and naval vessels.

The largest ship ever built in terms of gross tonnagethe Pioneering Spiritincorporates a catamaran design. Catamarans have two distinct primary performance characteristics that distinguish them from displacement monohull vessels: lower resistance to passage through the water and greater stability initial resistance to capsize. Choosing between a monohull and catamaran configuration includes considerations of carrying capacity, speed, and efficiency.

At low to moderate speeds, a lightweight catamaran hull experiences resistance to passage through water that is approximately proportional to the square of its speed. A displacement monohull, by catamaran sailboat manufacturers list data, experiences resistance that is at least the cube of its speed. This means that a catamaran would require four times the power in order to double catamaran sailboat manufacturers list data speed, whereas a monohull would require eight times the power to double its catamaran sailboat manufacturers list data, starting at a slow speed.

For sailing catamarans, low forward resistance [36] allows the sails to derive power from attached flow[37] their most efficient mode�analogous to a wing�leading to the use of wingsails in racing craft. Catamarans rely primarily on form stability to resist heeling and capsize. One measure of the trade-off between speed and carrying capacity is the displacement Froude number Fn V[41] compared with calm water transportation efficiency.

Calm water transportation efficiency of a vessel is proportional to the full-load displacement and the maximum calm-water speed, divided by the corresponding power required. Large merchant vessels have a Fn V between one and catamaran sailboat manufacturers list data, whereas higher-performance powered catamarans may approach 2.

Each type of vessel has a corresponding calm water transportation efficiency, with large transport ships being in the range of �1, compared with for transport catamarans�denoting a higher efficiency per unit of payload for monohulls.

Two advances over the traditional catamaran are the small-waterplane-area twin hull SWATH and the wave-piercing configuration�the latter having become a widely favored design. SWATH reduces wave-generating resistance by moving displacement volume below the waterline, using a pair of tubular, submarine-like hulls, connected by pylons to the bridge deck with a narrow waterline cross-section.

The submerged hulls are minimally affected by waves. Creedwho presented his idea in and was later awarded a British patent for it in It was first used in the s and s as an evolution of catamaran design for use as oceanographic research vessels or submarine rescue ships. SWATH vessels compare with conventional powered catamarans of equivalent size, as follows: [45]. Wave-piercing catamarans employ a low-buoyancy bow on each hull that is pointed at the water line and rises aft, up to a level, to allow each hull to pierce waves, rather than ride over.

This allows higher speeds through waves than for a conventional catamaran. The spanning bridge deck may be configured catamaran sailboat manufacturers list data some of the characteristics of a normal V-hull, which allows it to penetrate the crests of waves. Wave-piercing catamaran designs have been employed for yachts, [49] passenger ferries, [50] and military vessels.

Technological advances catamerans have over traditional monohull craft include foils that lift racing catamarans out of the water, capacious and stable cruising vessels, and racers that have achieved average speeds on the open ocean, comparable to much larger vessels. A catamaran configuration fills a niche where speed and sea-kindliness is favored over bulk capacity. In larger vessels, this niche favors car ferries and military vessels for patrol or operation in the littoral zone.

Recreational catamaran sailboat manufacturers list data sport catamarans typically are designed to have a crew catamaran sailboat manufacturers list data two and be launched and landed from a beach. Most have a trampoline on the bridging structure, a rotating mast and full-length battens on the mainsail. Performance versions often have trapezes to allow the crew to hike out and counterbalance capsize forces during strong winds on certain points of sail.

For the 33rd America's Cupboth the defender and the challenger built foot 27 m long multihulls. The challenger, BMW Oracle Racing, used a trimaran, replacing its soft sail rig with a towering wing sail �the largest sailing wing ever built.

This represented a break from the traditional monohulls that had always been sailed in previous America's Cup series. Each yacht employed hydrofoils and a wing Catamaran Manufacturers Uk Data sail. Yachting has seen the development of multihulls over feet 30 m in length. Because of the prize money and prestige associated with this event, four new catamarans and two highly modified ones over feet 30 m in length were built to compete.

The largest, PlayStationowned by Steve Fossettwas feet 38 m long and had a mast which was feet 45 m above the water. Virtually all of the new mega-cats were built of pre-preg Many Sailboat Manufacturers Sell Kits China carbon fiber for strength and the lowest possible weight.

The Race was won by the Whitewater catamaran sailboat manufacturers list data called "cata-rafts"�for whitewater sports are widely spread in post-Soviet countries.

They consists of two inflatable hulls connected with a lattice scaffold. The frame of the tourist catamaran can be made of both aluminum duralumin pipes and from felled tree trunks. The inflatable part catamaran sailboat manufacturers list data two layers�an airtight balloon with inflation catamaran sailboat manufacturers list data and a shell made of dense tissue, protecting the balloon from mechanical damage.

Advantages of such catamarans are light weight, compactness and convenience in transportation the whole product is packed in one pack-backpack, suitable for air traffic standards and the speed of assembly 10�15 minutes for the inflation. Cruising sailors must make trade-offs among volume, useful load, speed, and cost in choosing a boat. Choosing a catamaran offers increased speed at the expense of reduced load per unit of cost.

Howard and Doane describe the following tradeoffs between cruising monohulls and catamarans: [40] A long-distance, offshore cruising monohull may be as short as 30 feet 9. In addition to greater speed, catamarans draw less water than do monohulls�little as 3 feet 0. Catamarans are harder to tack and take up more space in a marina. Cruising catamarans entail added expense for having two engines and two rudders.

Tarjan adds that cruising catamarans boats can maintain a comfortable nautical miles mi; km per day passage, with the racing versions recording well over nautical miles mi; km per day. In addition, they do not heel more than degrees, even at full catamaran sailboat manufacturers list data on a reach.

Powered cruising catamarans share many of the amenities found in a sail cruising catamaran. The saloon typically spans two hulls wherein are found the staterooms and engine compartments. As with catamaran sailboat manufacturers list data catamarans, this configuration minimizes boat motion in a seaway. It completed a circumnavigation of the globe in The s saw the introduction of catamarans as catamaran sailboat manufacturers list data ferriesas pioneered by Westermoen Hydrofoil in MandalNorway, which launched the Westamaran design in The Makar -class is a class of two large catamaran-hull survey ships built for the Indian Navy.

Or bring everyone in and make that a dozen inside or easily clear the cockpit for a long passage. Every Seawind provides flexibility and luxury while sacrificing none of the practicality that made previous Seawind models the success they are.

Seawinds provide unparalleled entertainment space while sacrificing nothing in offshore safety. Dual helm stations are found on every model, and offer degree visibility, even on the largest model. This allows the skipper to sail safely in crowded harbor conditions, and to keep an eye on the crew when offshore. Large targa tops offer protection from the harsh offshore conditions, both sun and rain, while panoramic opening windows provide ventilation as well as visibility.

Seawinds offer the protection of a pilothouse yacht, with the visibility Sailboat Mast Manufacturers California University of and helming advantages of a catamaran. Best of all, you can enjoy what many cats compromise on�visibility � for the skipper and crew, with degree views from the helm and saloon seats all within the protection of the fiberglass coachouse and targa top.

This explains the vertical bows, long-waterlines, hard chines and tall, well setback rig with square-top mainsail. The self-tacker jib and roller-furling spinnaker are other innovations along with press-button electric winches that all make for easy sail handling with a small crew.

It goes without saying modern cats are very well engineered and safe for ocean crossings. Manufacturers have learnt the lessons from the top around-the-world racing multihulls and so modern designs are far less likely to pitch-pole or capsize.

You'll notice the inclusion of safety features like hull escape-hatches and dedicated stowage lockers for life-rafts. It's worth noting the typical sailing cat today performs pretty nicely under diesel auxiliary power. They are also very easy to manoeuvre in tight spaces, even turning on their own length with an engine in each hull.

Sailing level on a cat is not only fast but it's fun and your friends are less likely to spill their drinks. Plus you can actually enjoy those on-deck sun-beds under sail. When you get to a destination the shallow draft of a cat means you can enter that beautiful lagoon or shallow inlet where keel yachts can't go. And with a broad transom you can have a large outboard RIB inflatable ready to whisk you ashore quickly and in style.

Captain Jack Sparrow would love it! AQUILA This is a purposed design power cat that features hard-chine hulls and a tunnel designed to enhance lift at speed. Top speeds of 20 knots are possible with the optional twin Volvo hp turbo-diesels in the popular Aquila 44, the first to be sold in Australia.

A triple-deck design ensures this is a super roomy craft and has the largest owner's staterooms you'll ever see in a pleasure boat under foot. Further information: Multihull Central, see www.
