CircumnavigationCircumnavigation is the complete navigation around an entire island, continent, or astronomical body (e.g. a planet or moon). This article focuses on the circumnavigation of Earth. The first circumnavigation of the Earth was the Magellan Expedition, which sailed from Sanlucar de Barrameda, Spain in 1519 and returned in 1522, after crossing the Atlantic, Pacific, and Indian oceans. Since the rise of commercial aviation in the late 20th century, circumnavigating Earth is straightforward, usually taking days instead of years.
Polynesian culturePolynesian culture is the culture of the indigenous peoples of Polynesia who share common traits in language, customs and society. The development of Polynesian culture is typically divided into four different historical eras: Exploration and settlement (c. 1800 BC – c. AD 700) Development in isolation (c. 700 – 1595) European encounter and colonization until World War II (1595–1946) Post-World War II period Maternal mitochondrial DNA analysis suggests that Polynesians, including Samoans, Tongans, Niueans, Cook Islanders, Tahitians, Hawaiians, Marquesans and Māori, are genetically linked to indigenous peoples of parts of Maritime Southeast Asia including those of Taiwanese aborigines.
Polynesian navigationPolynesian navigation or Polynesian wayfinding was used for thousands of years to enable long voyages across thousands of kilometers of the open Pacific Ocean. Polynesians made contact with nearly every island within the vast Polynesian Triangle, using outrigger canoes or double-hulled canoes. The double-hulled canoes were two large hulls, equal in length, and lashed side by side. The space between the paralleled canoes allowed for storage of food, hunting materials, and nets when embarking on long voyages.
YachtA yacht jɒt is a sailing or power vessel used for pleasure, cruising, or racing. There is no standard definition, though the term generally applies to vessels with a cabin intended for overnight use. To be termed a , as opposed to a , such a pleasure vessel is likely to be at least in length and may have been judged to have good aesthetic qualities. The Commercial Yacht Code classifies yachts and over as . Such yachts typically require a hired crew and have higher construction standards.
FerryA ferry is a watercraft that carries passengers, and sometimes vehicles and cargo, across a body of water. A small passenger ferry with many stops, such as in Venice, Italy, is sometimes called a water taxi or water bus. Ferries form a part of the public transport systems of many waterside cities and islands, allowing direct transit between points at a capital cost much lower than bridges or tunnels. Ship connections of much larger distances (such as over long distances in water bodies like the Mediterranean Sea) may also be called ferry services, and many carry vehicles.
Maritime Southeast AsiaMaritime Southeast Asia comprises the countries of Brunei, Indonesia, Malaysia, the Philippines, Singapore, and East Timor. The term Island Southeast Asia or Insular Southeast Asia is 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.
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. 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.
Hull (watercraft)A hull is the watertight body of a ship, boat, or flying boat. The hull may open at the top (such as a dinghy), or it may be fully or partially covered with a deck. Atop the deck may be a deckhouse and other superstructures, such as a funnel, derrick, or mast. The line where the hull meets the water surface is called the waterline. There is a wide variety of hull types that are chosen for suitability for different usages, the hull shape being dependent upon the needs of the design.
RowingRowing is the act of propelling a human-powered watercraft using the sweeping motions of oars to displace water and generate reactional propulsion. Rowing is functionally similar to paddling, but rowing requires oars to be mechanically attached to the boat, and the rower drives the oar like a lever, exerting force in the same direction as the boat's travel; while paddles are completely hand-held and have no attachment to the boat, and are driven like a cantilever, exerting force opposite to the intended direction of the boat.
