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 ...

Multihull
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 ...

Victor Tchetchet
Victor Tchetchet (June 19, 1891 – April 26, 1974) was a pioneering early modern multihull sailboat designer from Ukraine (at his birth part of the Russian Empire) who is thought to have coined the term 'trimaran', though Éric de Bisschop built a trimaran in France earlier. He was also a landscape and portrait painter. Born in Kyiv, Victor was inspired by South Pacific outriggers to connect two canoes to make a catamaran and enter the Kyiv Imperial Yacht Club's local races. After winning, he was disqualified. In 1923 Tchetchet emigrated to New York City and further experimented with catamarans and trimarans. In 1945 he launched his first trimaran, of length. Tchetchet entered the Marblehead Race Week in 1946. Despite a poor performance, his participation helped to overcome the local prejudice against multihulls after Nathanael Herreshoff's 1876 win with the catamaran ''Amaryllis'' at the New York Yacht Club's Centennial Regatta. In the same year, he established the Intern ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Austronesian Peoples
The Austronesian people, sometimes referred to as Austronesian-speaking peoples, are a large group of peoples who have settled in Taiwan, maritime Southeast Asia, parts of mainland Southeast Asia, Micronesia, coastal New Guinea, Island Melanesia, Polynesia, and Madagascar that speak Austronesian languages. They also include indigenous ethnic minorities in Vietnam, Cambodia, Myanmar, Thailand, Hainan, the Comoros, and the Torres Strait Islands. The nations and territories predominantly populated by Austronesian-speaking peoples are sometimes known collectively as Austronesia. The group originated from a prehistoric seaborne migration, known as the Austronesian expansion, from Taiwan, circa 3000 to 1500 BCE. Austronesians reached the Batanes Islands in the northernmost Philippines by around 2200 BCE. They used sails some time before 2000 BCE. In conjunction with their use of other maritime technologies (notably catamarans, outrigger boats, lashed-lug boats, and the crab ...

Single-outrigger
Outrigger boats are various watercraft featuring one or more lateral support floats known as outriggers, which are fastened to one or both sides of the main hull. They can range from small dugout canoes to large plank-built vessels. Outrigger boats can also vary in their configuration, from the ancestral double-hull configuration (catamarans), to single-outrigger vessels prevalent in the Pacific Islands and Madagascar, to the double-outrigger vessels (trimarans) prevalent in Island Southeast Asia. They are traditionally fitted with Austronesian sails, like the crab claw sails and tanja sails, but in modern times are often fitted with petrol engines. Unlike a single-hulled vessel, an outrigger or double-hull vessel generates stability as a result of the distance between its hulls rather than due to the shape of each individual hull. As such, the hulls of outrigger or double-hull boats are typically longer, narrower and more hydrodynamically efficient than those of single-hull v ...

Maritime Southeast Asia
Maritime Southeast Asia comprises the Southeast Asian countries of Brunei, Indonesia, Malaysia, the Philippines, Singapore, and East Timor. The terms Island Southeast Asia and Insular Southeast Asia are sometimes given the same meaning as Maritime Southeast Asia. Other definitions restrict Island Southeast Asia to just the islands between mainland Southeast Asia and the continental shelf of Australia and New Guinea. There is some variability as to whether Taiwan is included in this. Peter Bellwood includes Taiwan in his definition, as did Robert Blust, whilst there are examples that do not. The 16th-century term " East Indies" and the later 19th-century term " Malay Archipelago" are also used to refer to Maritime Southeast Asia. In Indonesia, the Old Javanese term " Nusantara" is also used as a synonym for Maritime Southeast Asia. The term, however, is nationalistic and has shifting boundaries. It usually only encompasses Peninsular Malaysia, the Sunda Islands, Ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Balatik Paraw Trimaran (cropped)
Paraw (also spelled ''parao'') are various double outrigger sail boats in the Philippines. It is a general term (similar to the term '' bangka'') and thus can refer to a range of ship types, from small fishing canoes to large merchant lashed-lug plank boats (''balangay'' or ''baloto'') with two outriggers (''katig'') propelled by sails (usually a large crab-claw sail opposite a smaller triangular foresail) Etymology The word ''paraw'' (also spelled ''parao'') is a cognate of the terms ''proa'' of the Pacific Islands, and '' perahu'' or ''prau'' of Malay-Indonesia. It refers to outrigger boats propelled by sails (''layag''). It is a type of '' bangka'', the wider term used for boats (with or without outriggers) in the Philippines. Characteristics The paraw has three major elements that make it a paraw: the ''bangka'' (canoe or main hull), the ''katig'' (outriggers), and the ''layag'' (sails). Motorized versions of bangkas (with outriggers) are commonly known as pump boa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tacking (sailing)
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 ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iranun Lanong Warship By Rafael Monleón (1890)
The Iranun are an Austronesian peoples, Austronesian ethnic group native to southwestern Mindanao, Philippines. They are ethnically and culturally closely related to the Maranao people, Maranao, and Maguindanao people, Maguindanaon, all three groups being denoted as speaking Danao languages and giving name to the island of Mindanao. The Iranun were traditionally sailors and were renowned for their ship-building skills. Iranun communities can also be found in Malaysia. Origins The origin of the name "Iranun" remains contested. The "Iranun" (Archaism, archaic "Iranaoan") may have been the original endonym of the ancestral group which later split into the Iranun, Maranao, and Maguindanao people. The Iranun and Maranao still speak the language closest to the ancient Proto-Danaw among all of the Danao languages spoken by these groups. Regions The Iranun are native to the southwestern regions of Mindanao. Iranun are found Maguindanao del Norte (Barira, Maguindanao, Barira, Buldon, P ...

Leeward
In geography and seamanship, windward () and leeward () are directions relative to the wind. Windward is ''upwind'' from the point of reference, i.e., towards the direction from which the wind is coming; leeward is ''downwind'' from the point of reference, i.e., along the direction towards which the wind is going. The side of a ship that is towards the leeward is its "lee side". If the vessel is heeling under the pressure of crosswind, the lee side will be the "lower side". During the Age of Sail, the term ''weather'' was used as a synonym for ''windward'' in some contexts, as in the '' weather gage''. Since it captures rainfall, the windward side of a mountain tends to be wetter than the leeward side it blocks. The drier leeward area is said to be in a rain shadow. Origin The term "windward" has roots in both Low German and Old English. The word "lee", which means a place without wind, comes from the Old Norse "hle" for "cover" and has been used in marine navigation in G ...
