Baurua
The baurua was a traditional sailing proa of the Gilbert Islands. They are considered to have been the most sophisticated of the Austronesian sailing vessels. A 100-foot baurua was built in 1939.

Proa
Proas are various types of multi-hull outrigger sailboats of the Austronesian peoples. The terms were used for native Austronesian ships in European records during the Colonial era indiscriminately, and thus can confusingly refer to the double-ended single-outrigger boats of Oceania, the double-outrigger boats of Island Southeast Asia, and sometimes ships with no outriggers or sails at all. In its most common usage, the term ''proa'' refers to the Pacific proas which consist of two (usually) unequal-length parallel hulls. It is sailed so that one hull is kept to windward, and the other to leeward. It is double-ended, since it needs to " shunt" to reverse direction when tacking. It is most famously used for the '' sakman'' ships of the Chamorro people of the Northern Marianas, which were known as the "flying proas" for their remarkable speed. In Island Southeast Asia, the term ''proa'' may also sometimes be used, but the terms perahu, prau, prahu, paraw and prow a ...

Sailing
Sailing employs the wind—acting on sails, wingsails or kites—to propel a craft on the surface of the ''water'' (sailing ship, sailboat, raft, windsurfer, or kitesurfer), on ''ice'' (iceboat) or on ''land'' (land yacht) over a chosen course, which is often part of a larger plan of navigation. From prehistory until the second half of the 19th century, sailing craft were the primary means of maritime trade and transportation; exploration across the seas and oceans was reliant on sail for anything other than the shortest distances. Naval power in this period used sail to varying degrees depending on the current technology, culminating in the gun-armed sailing warships of the Age of Sail. Sail was slowly replaced by steam as the method of propulsion for ships over the latter part of the 19th century – seeing a gradual improvement in the technology of steam through a number of stepwise developments. Steam allowed scheduled services that ran at higher average speeds than sai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gilbert Islands
The Gilbert Islands ( gil, Tungaru;Reilly Ridgell. ''Pacific Nations and Territories: The Islands of Micronesia, Melanesia, and Polynesia.'' 3rd. Ed. Honolulu: Bess Press, 1995. p. 95. formerly Kingsmill or King's-Mill IslandsVery often, this name applied only to the southern islands of the archipelago, the northern half being designated as the Scarborough Islands. ''Merriam-Webster's Geographical Dictionary''. Springfield, Massachusetts: Merriam Webster, 1997. p. 594) are a chain of sixteen atolls and coral islands in the Pacific Ocean, about halfway between Papua New Guinea and Hawaii. They constitute the main part of the nation of Kiribati (the name of which is a rendering of “Gilberts” in the phonology of the indigenous Gilbertese). Geography The atolls and islands of the Gilbert Islands are arranged in an approximate north-to-south line. The northernmost island in the group, Makin, it is approximately from southernmost, Arorae, as the crow flies. Geographically, th ...

Multihull
A multihull is a boat or ship with more than one 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. Sailing multihulls Counter-intuitively, it is unhelpful to think of the design progression to be "1-2-3", namely monohull - catamaran - trimaran; rather, it is "1-3-2". A sailing trimaran is, in effect, a modified monohull with lightweight outrigger hulls (or "amas") for stability instead of a heavy deep keel; so it follows that a sailing trimaran will be lighter and faster than a sailing monohull. A sailing trimaran will have a centre hull that may comprise up to 90% of total hull volume, and 95% of total deadweight. A sailing trimaran at rest will have both amas out of the water and, when heeled, will only ever have one of the amas immersed. As ...

Wa (watercraft)
''Wa'' are traditional sailing outrigger canoes of the Caroline Islands, Palau, and Yap. They have a single outrigger. They are similar to the '' sakman'' of the Northern Marianas. Design and construction ''Wa'' are proa — vessels with identical bow and stern, allowing the craft to reverse without turning. They are made from hewn-out hulls, typically breadfruit trunks, with single wide top-strakes, and carved head and stern pieces. Sails are lateen rigged and were traditionally made of pandanus mat sailcloth. Benjamin Morrell recorded in the 1830s that sails were "made in small pieces of about three feet square, sewed together. In cutting the sail to its proper shape, the pieces which come off one side answer to go on the other; this gives it the proper form, and causes the halliards to be bent on in the middle of the yard." After World War II sails switched to canvas, and after 1973 the use of dacron began to increase. Early accounts agreed upon "a lee-platform on the side ...
