Variable-pitch Propeller (marine)
In marine propulsion, a variable-pitch propeller is a type of propeller with blades that can be rotated around their long axis to change the blade pitch. Reversible propellers—those where the pitch can be set to negative values—can also create reverse thrust for braking or going backwards without the need to change the direction of shaft revolution. A controllable pitch propeller (CPP) can be efficient for the full range of rotational speeds and load conditions, since its pitch will be varied to absorb the maximum power that the engine is capable of producing. When fully loaded, a vessel will need more propulsion power than when empty. By varying the propeller blades to the optimal pitch, higher efficiency can be obtained, thus saving fuel. A vessel with a VPP can accelerate faster from a standstill and can decelerate much more effectively, making stopping quicker and safer. A CPP can also improve vessel maneuverability by directing a stronger flow of water onto the ru ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prince William Sound
Prince William Sound (Sugpiaq: ''Suungaaciq'') is a sound of the Gulf of Alaska on the south coast of the U.S. state of Alaska. It is located on the east side of the Kenai Peninsula. Its largest port is Valdez, at the southern terminus of the Trans-Alaska Pipeline System. Other settlements on the sound, which contains numerous small islands, include Cordova and Whittier plus the Alaska native villages of Chenega and Tatitlek. History James Cook entered Prince William Sound in 1778 and initially named it Sandwich Sound, after his patron the Earl of Sandwich. Later that year, the Sound was named to honour George III's third son Prince William Henry, then aged 13 and serving as a midshipman in the Royal Navy. In 1790, the Spanish explorer Salvador Fidalgo entered the sound, naming many of its features. Some places in the sound still bear the names given by Fidalgo, as Port Valdez, Port Gravina or Cordova. The explorer landed on the actual site of Cordova and took possession of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peril Strait
Peril Strait or Shee Káx’ is a strait in the Alexander Archipelago in southeastern Alaska. It is between Chichagof Island to its north and Baranof Island and Catherine Island (Alaska), Catherine Island to its south. The strait is long and reaches from Salisbury Sound on the west to the Chatham Strait on the east. It is entirely within the limits of the Sitka City and Borough, Alaska, City and Borough of Sitka. __NOTOC__ Name Shee Káx’ comes from “Shee” which is the original name of Baranof Island. Káx’ is “above”, a locative description. The strait was named Proliv Pogibshy by Russians because of a fatal incident during a fur seal hunting expedition led by Alexander Andreyevich Baranov, Alexander Baranof in 1799. According to Yuri Lisianski, V. F. Lisianski, Baranof employed Native Aleut people, Aleut hunters, ate Paralytic shellfish poisoning, poisonous shellfish from the strait, which resulted in approximately one hundred and fifty deaths.

USCGC Woodrush (WLB-407)
USCGC ''Woodrush'' (WLB-407) was a buoy tender that performed general aids-to-navigation (ATON), search and rescue (SAR), and icebreaking duties for the United States Coast Guard (USCG) from 1944 to 2001 from home ports of Duluth, Minnesota and Sitka, Alaska. She responded from Duluth at full speed through a gale and high seas to the scene of the SS ''Edmund Fitzgerald'' sinking in 1975. In 1980, she took part in a rescue rated in the top 10 USCG rescues when she helped to save the passengers and crew of the cruise ship ''Prinsendam'' after it caught fire in position 57°38"N 140° 25"W then while being towed sank off Graham Island, British Columbia. She was one of the first vessels to respond to the ''Exxon Valdez'' oil spill in 1989. She was decommissioned on 2 March 2001 and sold to the Republic of Ghana to serve in the Ghana Navy. Construction and design ''Woodrush'' was built by the Zenith Dredge Company in Duluth, Minnesota as a , ''Iris'' or C-Class tender. He ...

Saint Lawrence Seaway
The St. Lawrence Seaway (french: la Voie Maritime du Saint-Laurent) is a system of locks, canals, and channels in Canada and the United States that permits oceangoing vessels to travel from the Atlantic Ocean to the Great Lakes of North America, as far inland as Duluth, Minnesota, at the western end of Lake Superior. The seaway is named for the St. Lawrence River, which flows from Lake Ontario to the Atlantic Ocean. Legally, the seaway extends from Montreal, Quebec, to Lake Erie, and includes the Welland Canal. Ships from the Atlantic Ocean are able to reach ports in all five of the Great Lakes. The St. Lawrence River portion of the seaway is not a continuous canal; rather, it consists of several stretches of navigable channels within the river, a number of locks, and canals along the banks of the St. Lawrence River to bypass several rapids and dams. A number of the locks are managed by the St. Lawrence Seaway Management Corporation in Canada, and others in the United States b ...

Great Lakes
The Great Lakes, also called the Great Lakes of North America, are a series of large interconnected freshwater lakes in the mid-east region of North America that connect to the Atlantic Ocean via the Saint Lawrence River. There are five lakes, which are Lake Superior, Superior, Lake Michigan, Michigan, Lake Huron, Huron, Lake Erie, Erie, and Lake Ontario, Ontario and are in general on or near the Canada–United States border. Hydrologically, lakes Lake Michigan–Huron, Michigan and Huron are a single body joined at the Straits of Mackinac. The Great Lakes Waterway enables modern travel and shipping by water among the lakes. The Great Lakes are the largest group of freshwater lakes on Earth by total area and are second-largest by total volume, containing 21% of the world's surface fresh water by volume. The total surface is , and the total volume (measured at the low water datum) is , slightly less than the volume of Lake Baikal (, 22–23% of the world's surface fresh water ...

USCGC Maple Servicing NOAA Buoy
United States Coast Guard Cutter is the term used by the U.S. Coast Guard for its commissioned vessels. They are or greater in length and have a permanently assigned crew with accommodations aboard. They carry the ship prefix USCGC. History of the USCG cutters The Revenue Marine and the Revenue Cutter Service, as it was known variously throughout the late 18th and the 19th centuries, referred to its ships as cutters. The term is English in origin and refers to a specific type of vessel, namely, "a small, decked ship with one mast and bowsprit, with a gaff mainsail on a boom, a square yard and topsail, and two jibs or a jib and a staysail." With general usage, that term came to define any vessel of the United Kingdom's HM Customs and Excise and the term was adopted by the U.S. Treasury Department at the creation of what would become the Revenue Marine. Since that time, no matter what the vessel type, the service has referred to its vessels with permanently assigned ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Weather Buoy
Weather buoys are instruments which collect weather and ocean data within the world's oceans, as well as aid during emergency response to chemical spills, legal proceedings, and engineering design. Moored buoys have been in use since 1951, while drifting buoys have been used since 1979. Moored buoys are connected with the ocean bottom using either chains, nylon, or buoyant polypropylene. With the decline of the weather ship, they have taken a more primary role in measuring conditions over the open seas since the 1970s. During the 1980s and 1990s, a network of buoys in the central and eastern tropical Pacific Ocean helped study the El Niño-Southern Oscillation. Moored weather buoys range from in diameter, while drifting buoys are smaller, with diameters of . Drifting buoys are the dominant form of weather buoy in sheer number, with 1250 located worldwide. Wind data from buoys has smaller error than that from ships. There are differences in the values of sea surface temperatur ...
