47-foot Motor Lifeboat
The 47-foot MLB is the standard Lifeboat (rescue), lifeboat of the United States Coast Guard (USCG). The 47′ MLB is the successor to the 44-foot motor lifeboat, 44′ MLB, which were in service from 1963 until 2009. Design The 47′ MLB is designed to weather hurricane force winds and heavy seas, capable of surviving winds up to , breaking surf up to and impacts up to three G's. If the boat should capsize, it self-rights in less than ten seconds with all equipment fully functional. The boat's hull (watercraft), hull and superstructure are constructed entirely from 5456 marine grade aluminum. Designed with a hard Chine (boating), chined deep "V" Planing (sailing), planing hull, the 47′ MLB exceeds its hull speed. The frame is composed of 17 vertical bulkhead frames, each of which is welded to the deck and hull, and five of which are watertight. For the international version, Textron have modified the design slightly to use Caterpillar Inc., Caterpillar C12 diesel engines wi ...

Surf Zone
The surf zone or breaker zone is the nearshore part of a body of open water between the line at which the waves break and the shore. As ocean surface waves approach a shore, they interact with the bottom, wave shoaling, get taller and steeper, and break, forming the sea foam, foamy surface called ''surf''. The region of breaking waves defines the surf zone. After breaking in the surf zone, the waves (now reduced in height) continue to move in, and they run up onto the sloping front of the beach, forming an uprush of water called swash. The water then runs back again as Swash#Backwash current, backwash. The water in the surf zone is relatively shallow, depending on the height and period of the waves. Animal life The animals that often are found living in the surf zone are crabs, clams, and snails. Surf clams and mole crabs are two species that stand out as inhabitants of the surf zone. Both of these animals are very fast burrowers. The surf clam, also known as the variable coquina ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fly-by-wire
Fly-by-wire (FBW) is a system that replaces the conventional aircraft flight control system#Hydro-mechanical, manual flight controls of an aircraft with an electronic interface. The movements of flight controls are converted to electronic signals, and flight control computers determine how to move the actuators at each control surface to provide the ordered response. Implementations either use Aircraft flight control system, mechanical flight control backup systems or else are fully electronic.Fly by Wire Flight Control Systems Sutherland Improved fully fly-by-wire systems interpret the pilot's control inputs as a desired outcome and calculate the control surface positions required to achieve that outcome; this results in various combinations of rudder, Elevator (a ...

Trent-class Lifeboat
The Trent-class lifeboat is an all-weather lifeboat operated by the Royal National Lifeboat Institution (RNLI) from 20 stations (2025) around the coasts of Great Britain and Ireland to provide coverage up to out to sea. Introduced to service in 1994, the class is named after the River Trent, the second longest river wholly in England. History In the 1980s the RNLI's and all-weather lifeboats provided coverage out to sea, operating at up to to cover the distance in two hours in good weather. However the RNLI felt that they needed the capability to extend their coverage to radius which would require lifeboats with a top speed of . This resulted in the Trent and lifeboats. The prototype for the Trent class was built in 1991. It was used for trials until 1994, when it was put into active service at Alderney Lifeboat Station. It remained on station there until their own boat was available in 1995, since when it has served in the relief fleet. Construction of its sister bo ...

Canadian Coast Guard
The Canadian Coast Guard (CCG; ) is the coast guard of Canada. Formed in 1962, the coast guard is tasked with marine search and rescue (SAR), communication, navigation, and transportation issues in Canadian waters, such as navigation aids and icebreaking, marine pollution response, and support for other Canadian government initiatives. The Coast Guard operates 119 vessels of varying sizes and 23 helicopters, along with a variety of smaller craft. The CCG is headquartered in Ottawa, Ontario, and is a special operating agency within Fisheries and Oceans Canada (Department of Fisheries and Oceans).

Cape-class Motor Lifeboat
The Canadian Coast Guard (CCG) maintains a fleet of Cape-class motor lifeboats based on a motor lifeboat design used by the United States Coast Guard. In September 2009 the CCG announced plans to add five new lifeboats, bringing the total number of Cape-class lifeboats to 36. The vessels are staffed by a crew of four, of which at least one is a rescue specialist. In spite of its name, the CCGS ''Cape Roger'' is a larger patrol vessel, not a Cape-class lifeboat. The CCG also maintains some larger motor lifeboats based on Arun-class lifeboats designed in the United Kingdom. In 2021 a contract was awarded to Ocean Pacific Marine to upgrade the class over a 7 year period. Design Cape-class motor lifeboats have displacements of 33.79 GT, total lengths of and beams of . Constructed from marine-grade aluminium, ships have draughts of . They contain two Caterpillar 3196 diesel engines providing a combined . They have two counter-rotating, four-blade propellers. Each ship's ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
41-foot Utility Boat, Large
The USCG Ohio Boat, or UTB gynt, was a standard utility boat used by the United States Coast Guard for a variety of inshore and offshore missions. By 2014 all boats of this class had been retired, and replaced with the larger ''Response Boat – Medium'' (RB-M) in the USCG. General information The 41 ft (12 m) UTB was designed to operate under moderate weather and sea conditions where its speed and maneuverability made it an ideal platform; however, due to the modified "V" design when the 41ft UTB when operated in a following seaway it had a tendency to be pushed to the starboard or port making it difficult when entering an entrance. Overall, the 41ft UTB was a vast improvement over the previous 40ft UTB's as the previous UTB's offered little to no protection from the sun, sea and wind conditions for the crew. The boats were welded 5086 aluminum, with a molded fiberglass superstructure and twin Cummins diesel engines with conventional shafts and propellers. They were capab ...
