Baidarka
The baidarka or Aleutian kayak ( Aleut: iqyax) is a watercraft consisting of soft skin (artificial or natural) over a rigid space frame. Its initial design was created by the native Aleut (or Unangan) people of the Aleutian Islands. The Aleut people were surrounded by treacherous waters and required water transportation and a hunting vessel. Due to the geography and climate of the Aleutian Islands, trees and wood were in scarce supply and the people relied primarily on driftwood to create the framework of the kayak, which was covered with the skins of sea mammals. Two types of boats were created, one with a covered deck that was used as a hunting kayak, and another that was open and capable of carrying goods and people from one island to another. Modern baidarkas are fast collapsible rowing boats, based on aluminum alloy frame with skin made of PVC fabric. Often the inflatable buoyancy chambers are embedded into the skin, resulting in increased safety and performance. Some de ...

George Dyson (science Historian)
George Dyson (born 26 March 1953) is an American non-fiction author and historian of technology whose publications broadly cover the evolution of technology in relation to the physical environment and the direction of society. He has written on a wide range of topics, including the history of computing, the development of algorithms and intelligence, communications systems, space exploration, and the design of watercraft. Early life George Dyson is the son of the theoretical physicist Freeman Dyson and mathematician Verena Huber-Dyson, the brother of technology analyst Esther Dyson, and the grandson of the British composer Sir George Dyson. Dyson's early life is described in Kenneth Brower's book ''The Starship and the Canoe.'' When he was sixteen he went to live in British Columbia to pursue his interest in kayaking. From 1972 to 1975, he lived in a treehouse at a height of 30 metres that he built from salvaged materials on the shore of Burrard Inlet. Dyson became a Canad ...

Kayaks
A kayak is a small, narrow watercraft which is typically propelled by means of a double-bladed paddle. The word kayak originates from the Greenlandic word '' qajaq'' (). The traditional kayak has a covered deck and one or more cockpits, each seating one paddler. The cockpit is sometimes covered by a spray deck that prevents the entry of water from waves or spray, differentiating the craft from a canoe. The spray deck makes it possible for suitably skilled kayakers to roll the kayak: that is, to capsize and right it without it filling with water or ejecting the paddler. ] Some modern boats vary considerably from a traditional design but still claim the title "kayak", for instance in eliminating the cockpit by seating the paddler on top of the boat ("sit-on-top" kayaks); having inflated air chambers surrounding the boat; replacing the single hull with twin hulls; and replacing paddles with other human-powered propulsion methods, such as foot-powered rotational propellers and ...

Umiak
The umiak, umialak, umiaq, umiac, oomiac, oomiak, ongiuk, or anyak is a type of open skin boat, used by both Yupik and Inuit, and was originally found in all coastal areas from Siberia to Greenland. First arising in Thule times, it has traditionally been used in summer to move people and possessions to seasonal hunting grounds and for hunting whales and walrus.Umiaks at the Canadian Museum of Civilization Although the umiak was usually propelled by oars (women) or paddles (men), sails—sometimes made from seal s—were also used, and in the 20th century, [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sergie Sovoroff
Sergie Sovoroff (September 17, 1901 – September 27, 1989) was an Aleut educational leader. He was born on Umnak Island in the Aleut village of Nikolski in 1902. Sovoroff was born only nine years before the United States government outlawed sea otter hunting. After 1911, the need and use of ''iqya-x'', Aleut sea kayaks, declined abruptly. But Sovoroff continued to see a need for creating model sea kayaks, known in his days by the Russian name "baidarka". Sovoroff "...kept up the tradition of making kayak models". Model sea kayaks built by Sovoroff, quite often with three hatches with a Russian Orthodox priest seated in the middle hatch, can be seen in many museums around the world. These model sea kayaks, finely crafted by Sovoroff, often equipped with a rudder on the stern of the kayak, all too frequently bear the name of the person who purchased them or donated them to the museum, and not Sovoroff's. Sergie died on September 27, 1989 and is buried in Nikolski, Alaska. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Drift Wood
__NOTOC__ Driftwood is wood that has been washed onto a shore or beach of a sea, lake, or river by the action of winds, tides or waves. In some waterfront areas, driftwood is a major nuisance. However, the driftwood provides shelter and food for birds, fish and other aquatic species as it floats in the ocean. Gribbles, shipworms and bacteria decompose the wood and gradually turn it into nutrients that are reintroduced to the food web. Sometimes, the partially decomposed wood washes ashore, where it also shelters birds, plants, and other species. Driftwood can become the foundation for sand dunes. Most driftwood is the remains of trees, in whole or part, that have been washed into the ocean, due to flooding, high winds, or other natural occurrences, or as the result of logging. There is also a subset of driftwood known as drift lumber. Drift lumber includes the remains of man-made wooden objects, such as buildings and their contents washed into the sea during storms, woode ...

Pinniped
Pinnipeds (pronounced ), commonly known as seals, are a widely range (biology), distributed and diverse clade of carnivorous, fin-footed, semiaquatic, mostly marine mammal, marine mammals. They comprise the extant taxon, extant family (biology), families Odobenidae (whose only living member is the walrus), Otariidae (the eared seals: sea lions and fur seals), and Phocidae (the earless seals, or true seals). There are 34 extant species of pinnipeds, and more than 50 extinct species have been described from fossils. While seals were historically thought to have descended from two ancestral lines, molecular phylogenetics, molecular evidence supports them as a monophyletic lineage (descended from one ancestral line). Pinnipeds belong to the order Carnivora; their closest living relatives are Musteloidea, musteloids (Mustelidae, weasels, Procyonidae, raccoons, skunks, and red pandas), having diverged about 50 million years ago. Seals range in size from the and Baikal sea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bow (ship)
The bow () is the forward part of the hull of a ship or boat, the point that is usually most forward when the vessel is underway. The aft end of the boat is the stern. Prow may be used as a synonym for bow or it may mean the forward-most part of the bow above the waterline. Function A ship's bow should be designed to enable the hull to pass efficiently through the water. Bow shapes vary according to the speed of the boat, the seas or waterways being navigated, and the vessel's function. Where sea conditions are likely to promote pitching, it is useful if the bow provides reserve buoyancy; a flared bow (a raked stem with flared topsides) is ideal to reduce the amount of water shipped over the bow. Ideally, the bow should reduce the resistance and should be tall enough to prevent water from regularly washing over the top of it. Large commercial barges on inland waterways rarely meet big waves and may have remarkably little freeboard at the bow, whereas fast military ve ...
