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]
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.
A sailboat's mast is supported by shrouds (side-to-side) and stays (fore-and-aft) – nautical equivalents of guy wires.. A guy-wire, guy-line, guy-rope, down guy, or stay, also called simply a guy, is a tensioned cable designed to add stability to a freestanding structure.
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 ...
The former cable ferry at Malgas in South Africa even carried several cars, pulled by a couple of men at a slow walking speed. Ferries of this size that were hand-operated, such as the Reedham Ferry, have since been motorised in order to reduce the level of hard work and increase the speed. For these and other ferries of up to 20 t or so ...
On nautical charts, the top of the chart is always true north, rather than magnetic north, towards which a compass points. Most charts include a compass rose depicting the variation between magnetic and true north. However, the use of the Mercator projection has drawbacks. This projection shows the lines of longitude as parallel.
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 ...
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.
