V-drive
A V-drive is a transmission (mechanics), power transmission system for boats that consists (usually) of two gearboxes, two drive shafts, and a propeller. Whereas the conventional arrangement sites the marine propulsion, engine with its gearbox aft, driving the propeller shaft directly, in a "V-drive" layout, the engine is reversed, to have the gearbox in front. This primary gearbox typically drives a short shaft forward to a transfer gearbox which reverses the transmission (mechanics), transmission to the main tailshaft which is directed rearwards the propeller, at a "V" angle to the short shaft. A V-drive system variation is for the tailshaft to drive a saildrive propeller, mounted on a skeg below the hull. This is common on Lagoon catamaran, Lagoon catamarans. A variation of the two-shaft V-Drive layout is the "close-coupled V-drive" whereby the engine is still mounted "back-to-front", but the main gearbox incorporates an output flange that has already been reversed.

Motorboat
A motorboat or powerboat is a boat that is exclusively powered by an engine; faster examples may be called "speedboats". Some motorboats are fitted with inboard engines, others have an outboard motor installed on the rear, containing the internal combustion engine, the gearbox and the propeller in one portable unit. An inboard-outboard contains a hybrid of an inboard and an outboard, where the internal combustion engine is installed inside the boat, and the gearbox and propeller are outside. There are two configurations of an inboard, V-drive and direct drive. A direct drive has the powerplant mounted near the middle of the boat with the propeller shaft straight out the back, where a V-drive has the powerplant mounted in the back of the boat facing backwards having the shaft go towards the front of the boat then making a ''V'' towards the rear. Overview A motorboat is a small craft with one or more engines for propulsion. Motorboats are commonly used for work, recreation ...

Blue Bird K3
''Blue Bird K3'' is a hydroplane powerboat commissioned in 1937 by Sir Malcolm Campbell, to rival the Americans' efforts in the fight for the world water speed record. She set three world water speed records, first on Lake Maggiore in September 1937, then later twice raising her own record. The name "K3" was derived from its Lloyd's unlimited rating, and was carried in a prominent circular badge on the forward hull. Design After Campbell's achievement of the 300 mph land speed record with ''Blue Bird'' in 1935 he retired from advancing the land speed record. Shortly afterwards he switched his attentions to the water speed record, at that time dominated by the American Gar Wood. ''Blue Bird K3'' was designed by Fred Cooper and built by Fred Goatley of Saunders-Roe. The design was intended to be the smallest possible hull capable of carrying the Rolls-Royce R racing engine. Campbell had already used this engine in his ''Blue Bird'' car, and they had also been used in p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Malcolm Campbell
Major Sir Malcolm Campbell (11 March 1885 – 31 December 1948) was a British racing motorist and motoring journalist. He gained the world speed record on land and on water at various times, using vehicles called ''Blue Bird'', including a 1921 Grand Prix Sunbeam. His son, Donald Campbell, carried on the family tradition by holding both land speed and water speed records. Early life and family Campbell was born on 11 March 1885 in Chislehurst, Kent, the only son of William Campbell, a Hatton Garden diamond seller. He attended the independent Uppingham School. In Germany, learning the diamond trade, he gained an interest in motorbikes and races. Returning to Britain, he worked for two years at Lloyd's of London for no pay, then for another year at £1 a week. Between 1906 and 1908, he won all three London to Land's End Trials motorcycle races. In 1910, he began racing cars at Brooklands. He christened his car ''Blue Bird'', painting it blue, after seeing the play '' The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sterndrive
A sterndrive or inboard/outboard drive (I/O) is a form of marine propulsion which combines inboard power with outboard drive. The engine sits just forward of the transom while the drive unit (outdrive or drive leg) lies outside the hull. Operation The drive unit (outdrive) carries power from the inboard engine, typically mounted above the waterline, outboard through the transom and downward to the propeller below the waterline. The outdrive resembles the bottom half of an outboard motor and is composed of two sub-units: an upper containing a driveshaft connected through the transom to an engine which transmits power to a 90-degree-angle gearbox; and the lower containing a vertical driveshaft receiving power from the upper unit gearbox, transmitted through another 90-degree-angle gearbox to the propeller shaft. The boat is steered by pivoting the outdrive, as on an outboard motor; no rudder is needed. The outdrive is pivoted up for trailer travel and between uses to avoid fo ...

Catamaran
A catamaran () (informally, a "cat") is a watercraft with two parallel hull (watercraft), hulls of equal size. The wide distance between a catamaran's hulls imparts stability through resistance to rolling and overturning; no ballast is required. Catamarans typically have less hull volume, smaller Displacement (ship), displacement, and shallower draft (hull), draft (draught) than monohulls of comparable length. The two hulls combined also often have a smaller hydrodynamic drag (physics), resistance than comparable monohulls, requiring less propulsive power from either sails or motors. The catamaran's wider stance on the water can reduce both Heeling (sailing)#Heeling, heeling and wave-induced motion, as compared with a monohull, and can give reduced wakes. Catamarans were invented by the Austronesian peoples, and enabled their expansion to the islands of the Indian Ocean, Indian and Pacific Oceans. Catamarans range in size from small sailing or rowing vessels to large naval s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cruising Yacht
A cruising yacht is a sailing or motor yacht that is suitable for long-distance travel and offers enough amenities to live aboard the boat, yet is small enough to not require a professional crew. A yacht that would require a professional crew enters the category of superyacht. Sail Sailing cruising yachts are designed for multi-day voyages with the capacity for overnight passage making. Their range and endurance relies primarily on sail power and the storage of provisions for the crew.

Transmission (mechanics)
A transmission (also called a gearbox) is a mechanical device invented by Louis Renault (industrialist), Louis Renault (who founded Renault, Renault) which uses a gear set—two or more gears working together—to change the speed, direction of rotation, or torque multiplication/reduction in a machine. Transmissions can have a single fixed-gear ratio, multiple distinct gear ratios, or continuously variable ratios. Variable-ratio transmissions are used in all sorts of machinery, especially vehicles. Applications Early uses Early transmissions included the right-angle drives and other gearing in windmills, horse-powered devices, and steam engine, steam-powered devices. Applications of these devices included pumps, mill (grinding), mills and Hoist (device), hoists. Bicycles Bicycles traditionally have used hub gear or Derailleur gear transmissions, but there are other more recent design innovations. Automobiles Since the torque and Horsepower, power output of an interna ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lagoon Catamaran
Lagoon catamaran is a brand of twin-hulled boats that are designed and produced in Bordeaux, France. The company began in 1984 as a specialist multihull division of Jeanneau, a volume monohull constructor. Jeanneau sold the division to Construction Navale Bordeaux (CNB), which was purchased by Beneteau in 1995, another French boat manufacturer. Lagoon is the world's largest multihull builder with 5800 catamarans produced since 1984. The company specialises in modern sailing catamarans that are suitable for both coastal and offshore sailing. Most models are available in a charter version and an owner's version. The designers, Marc Van Peteghem and Vincent Lauriot-Prévost at VPLP design, claim to be very responsive to customer feedback, thus enabling the designs to evolve over time. Lagoon catamarans have been well-received, and the Lagoon 380 has been their most successful model. Lagoon have also produced some power catamarans, including the Lagoon Power 43 and Lagoon Power 44. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
