The Folding Boat Equipment, abbreviated as FBE, is a light pontoon bridging equipment which was in use by the British and its colonial armies during the 20th century. [1] The equipment was introduced in 1928 and was the standard light bridge used for loads up to class 5, i.e. providing rafts or a bridge capable of transporting loads up to 5 ...
The machinery is specifically designed for anchor handling operations. They also have arrangements for quick anchor release, which is operable from the bridge or other normally crewed locations in direct communication with the bridge. The reference load used in the design and testing of the towing winch is twice the static bollard pull.
The engines are coupled to two 4.6-metre (15 ft) Schottel controllable-pitch propeller in nozzles via Flender reduction gearboxes. [ 1 ] [ 62 ] The propulsion system gives Aiviq a service speed of 15 knots (28 km/h; 17 mph) in open water and 5 knots (9.3 km/h; 5.8 mph) in 1-metre (3 ft 3 in) level ice, and a bollard pull of 200 metric tons.

A pontoon bridge is a collection of specialized, shallow draft boats or floats, connected together to cross a river or canal, with a track or deck attached on top. The water buoyancy supports the boats, limiting the maximum load to the total and point buoyancy of the pontoons or boats. [ 2 ]
A pontoon boat is a flattish boat that relies on nautical floats for buoyancy. Common boat designs are a catamaran with two pontoons, or a trimaran with three. [2] In many parts of the world, pontoon boats are used as small vehicle ferries to cross rivers and lakes. [3] An anchored raft-like platform used for diving, often referred to as a pontoon
A pleasure boat with two lengthwise pontoons. A pontoon boat is a flattish boat that relies on floats to remain buoyant. These pontoons (also called tubes) contain much reserve buoyancy and allow designers to create large deck plans fitted with a variety of accommodations including expansive lounge areas, stand-up bars, and sun pads.
Hull speed or displacement speed is the speed at which the wavelength of a vessel's bow wave is equal to the waterline length of the vessel. As boat speed increases from rest, the wavelength of the bow wave increases, and usually its crest-to-trough dimension (height) increases as well. When hull speed is exceeded, a vessel in displacement mode ...
As the frictional drag of a displacement hull decreases with about the third power of the speed, even the smallest amount of power can effect movement with enough leverage or if suitably geared down. The majority of the world's cable ferries are indeed manually propelled either with a crank turning a chain wheel or by pulling directly on a cable.
