Multihulls
A multihull is a boat or ship with more than one Hull (watercraft), hull, whereas a vessel with a single hull is a monohull. The most common multihulls are catamarans (with two hulls), and trimarans (with three hulls). There are other types, with four or more hulls, but such examples are very rare and tend to be specialised for particular functions. Multihull history Single-outrigger boats, double-canoes (catamarans), and double-outrigger boats (trimarans) of the Austronesian peoples are the direct antecedents of modern multihull vessels. They were developed during the Austronesian Expansion (c. 3000 to 1500 BC) which allowed Austronesians to colonize maritime Southeast Asia, Micronesia, Island Melanesia, Madagascar, and Polynesia. These Austronesian vessels are still widely used today by traditional fishermen in Austronesian regions in maritime Southeast Asia, Oceania and Madagascar; as well as areas they were introduced to by Austronesians in ancient times like in the East ...

James Wharram
James Wharram (15 May 1928 – 14 December 2021) was a British multihull pioneer and designer of catamarans. Polynesian beginnings Wharram was born in Manchester, England. In 1953, after long studies into the records of boats of the Pacific in the libraries and museums of Britain, and inspired by Eric de Bisschop's book ''The voyage of the Kaimiloa'', he designed and built the first British ocean-going double-canoe-catamaran, the ''Tangaroa'' (length ) and in 1955–56 sailed with Jutta Schultze-Rhonhof and Ruth Merseburger, across the Atlantic to Trinidad – the beginning of cruising (maritime), cruising and transatlantic crossing with a catamaran. No scholars in the Western world at this time believed that the Polynesians had boats capable of directed ocean voyages. Wharram believed otherwise and set out to prove it by doing it himself. He followed this first Atlantic crossing by building a 40-foot V-hull double canoe, ''Rongo (catamaran), Rongo'', in Trinidad in 1957–58, wit ...

Trimaran
A trimaran (or double-outrigger) is a multihull boat that comprises a main hull and two smaller outrigger hulls (or "floats") which are attached to the main hull with lateral beams. Most modern trimarans are sailing yachts designed for recreation or racing; others are ferries or warships. They originated from the traditional double-outrigger hulls of the Austronesian cultures of Maritime Southeast Asia; particularly in the Philippines and Eastern Indonesia, where it remains the dominant hull design of traditional fishing boats. Double-outriggers are derived from the older catamaran and single-outrigger boat designs. Terminology The word "trimaran" is a portmanteau of "tri" and "(cata)maran", a term that is thought to have been coined by Victor Tchetchet, a pioneering, Ukrainian-born modern multihull designer. Trimarans consist of a main hull connected to outrigger floats on either side by a crossbeam, wing, or other form of superstructure—the traditional Polynesian te ...

Farrier Marine
Farrier Marine is a catamaran and trimaran manufacturer based in Christchurch, New Zealand. The sailing boats produced by this shipyard are designed by Ian Farrier (1947-2017), and have a unique patented folding system without hinges in the beams or the critical beam to float join, allowing overall beam to be varied in seconds by just one person. History After gaining hands-on experience from building and sailing his own sailboats, Ian Farrier designed a trimaran folding system and applied in 1973 for a patent that was granted in 1975 as the Farrier Folding System. In 1974, the original prototype was built and launched by Farrier in Australia, followed in 1976 by the first Trailertri 18, and in 1980 by the first production fiberglass Farrier trimaran, the 'Tramp', that was named Australian Boat of the Year in 1981. In 1984, Ian Farrier funded by Corsair Marine in the US and started designing and building the F-27 trimaran ''Super Fox'' which set a race record in her first offi ...

Arthur Piver
Arthur Piver (; "Piver rhymes with diver"; 1910–1968) was a World War II pilot, an amateur sailor, author, printshop owner and renowned boatbuilder who lived in Mill Valley on San Francisco Bay and became "the father of the modern multihull." Career In the late 1950s and 1960s Piver designed and built a series of simple three-hulled, plywood yachts starting with a 16 footer and culminating in a 64-footer that was built in England for charter in the Caribbean. (The word "trimaran" was coined by Viktor Tchetchet, a Ukrainian emigrant to the US who tested his boats on Long Island sound in the late 1940s.) Piver crossed the Atlantic on his first ocean-going boat, the demountable 30 foot ''Nimble'', departing from Swansea, Mass, stopping in the Azores, and successfully reaching Plymouth, England. He then began selling do-it-yourself plans through a company called '' Pi-Craft''. He thought anyone could build one of his boats even if they had no experience. In 1962, Piver built hims ...

Catamaran
A catamaran () (informally, a "cat") is a watercraft with two parallel hull (watercraft), hulls of equal size. The wide distance between a catamaran's hulls imparts stability through resistance to rolling and overturning; no ballast is required. Catamarans typically have less hull volume, smaller Displacement (ship), displacement, and shallower draft (hull), draft (draught) than monohulls of comparable length. The two hulls combined also often have a smaller hydrodynamic drag (physics), resistance than comparable monohulls, requiring less propulsive power from either sails or motors. The catamaran's wider stance on the water can reduce both Heeling (sailing)#Heeling, heeling and wave-induced motion, as compared with a monohull, and can give reduced wakes. Catamarans were invented by the Austronesian peoples, and enabled their expansion to the islands of the Indian Ocean, Indian and Pacific Oceans. Catamarans range in size from small sailing or rowing vessels to large naval s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Asia
South Asia is the southern Subregion#Asia, subregion of Asia that is defined in both geographical and Ethnicity, ethnic-Culture, cultural terms. South Asia, with a population of 2.04 billion, contains a quarter (25%) of the world's population. As commonly conceptualised, the modern State (polity), states of South Asia include Bangladesh, Bhutan, India, the Maldives, Nepal, Pakistan, and Sri Lanka, with Afghanistan also often included, which may otherwise be classified as part of Central Asia. South Asia borders East Asia to the northeast, Central Asia to the northwest, West Asia to the west and Southeast Asia to the east. Apart from Southeast Asia, Littoral South Asia, Maritime South Asia is the only subregion of Asia that lies partly within the Southern Hemisphere. The British Indian Ocean Territory and two out of Atolls of Maldives, 26 atolls of the Maldives in South Asia lie entirely within the Southern Hemisphere. Topographically, it is dominated by the Indian subcontinent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lock Crowther
Lock Crowther (9 September 1940–1993; first name by birth Lachlan) was an Australian multihull sailboat designer. He grew up in Bairnsdale in the East Gippsland region of Victoria. Though his first name was Lachlan by birth, he insisted on being called Lock or Lockie. Career Lock and his family built his first boat, a trimaran called '' Bunyip'', in 1959 while he was still a teenager. In 1960 he raced in the Easter regatta at Paynesville, Victoria, Australia, and won against a field of 300 boats. This initial success inspired others to build similar boats. Crowther then studied electrical engineering in Melbourne and in the early 1960s became involved in multihull design and the '' Amateur Yacht Research Society''. In 1962 ''Trio'' was built based upon his designs. Crowther's next design was the Kraken 25, garnering some recognition. Later, Lockie decided to give up his day job in Melbourne and move to Sydney to design multihulls full-time. In 1969, a Kraken 40 won ...

Catalac Catamarans
Catalac is a defunct English maritime construction company that specialised in building sailing catamarans. The company was founded by Tom Lack (hence "Cata + Lac"), in Christchurch, Dorset. After a successful period of production, the company closed in 1986. In the 1990s, the Catalac 9M was briefly revived and updated in the US as the "Catalac 900". Catalac catamarans The Catalac company's main model was the 9-metre 9M. All the other models are derived from the 9M and use a similar design concept; the 8M even used the same hulls as the 9M. All Catalacs were very strongly-built with thick grp hulls and glass windows. Some of the superstructure, such as the solid foredeck, was of sandwich grp construction. Compared to modern designs, Catalacs had a narrow beam of less than half the LOA, and vertical transoms (rather than the more modern "sugar scoop" with transom steps). Initially featuring lifting dinghy-type rudders, Catalac moved to fixed rudders protected by a skeg; this ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tessarakonteres
''Tessarakonteres'' (, "forty-rowed"), or simply "forty", was a very large catamaran galley reportedly built in the Hellenistic period by Ptolemy IV Philopator of Ptolemaic Egypt, Egypt. It was described by a number of ancient sources, including a lost work by Callixenus of Rhodes and surviving texts by Athenaeus and Plutarch. According to these descriptions, supported by modern research by Lionel Casson, the enormous size of the vessel made it impractical and it was built only as a prestige vessel, rather than an effective warship. The name "forty" refers not to the number of oars, but to the number of rowers on each vertical "column" of oars that propelled it, and at the size described it would have been the List of world's largest wooden ships, largest ship constructed in antiquity, and probably the largest human-powered vessel ever built. Sources The "forty" was reportedly built by Ptolemy IV Philopator of Ptolemaic Egypt, Egypt in the 3rd century BC. It was first described ...
