Graphical representation of the dimensions used to describe a ship. Dimension "b" is the beam at waterline.. The beam of a ship is its width at its widest point. The maximum beam (B MAX) is the distance between planes passing through the outer sides of the ship, beam of the hull (B H) only includes permanently fixed parts of the hull, and beam at waterline (B WL) is the maximum width where the ...
Beam – A measure of the width of the ship. There are two types: Beam, Overall (BOA), commonly referred to simply as Beam – The overall width of the ship measured at the widest point of the nominal waterline. Beam on Centerline (BOC) – Used for multihull vessels. The BOC for vessels is measured as follows: For a catamaran: the ...
The first post-Panamax ship was the RMS Queen Mary, launched in 1934, built with a 118-foot beam as she was intended solely for North Atlantic passenger runs. When she was moved to Long Beach, California , as a tourist attraction in 1967, a lengthy voyage around Cape Horn was necessary. [ 30 ]
[31] [32] The third set of locks were built to accommodate a container ship with a length overall of 366 metres (1,201 ft), a maximum beam (width) of 49 metres (161 ft), and tropical fresh-water draft of 15.2 metres (50 ft).
beam The width of a vessel at its widest point, or a point alongside the ship at the midpoint of its length. beam ends The sides of a ship. To describe a ship as "on her beam ends" may mean the vessel is literally on her side and possibly about to capsize; more often, the phrase means the vessel is listing 45 degrees or more. beam reach
The typical deadweight of a Suezmax ship is about 160,000 tons; the typical beam (width) is about 48 m (157.5 ft). Also of note is the maximum head room—" air draft "—limitation of 68 m (223.1 ft), resulting from the 70-metre (230 ft) height above water of the Suez Canal Bridge .
Beam: 78 ft (23.8 m) Height: 116.5 ft (35.5 m) Draft: 26.51 ft (8.1 m) Comparison of bounding box of Seawaymax with some other ship sizes in isometric view.
Five definitions of the beam width are in common use: D4σ, 10/90 or 20/80 knife-edge, 1/e 2, FWHM, and D86. The beam width can be measured in units of length at a particular plane perpendicular to the beam axis, but it can also refer to the angular width, which is the angle subtended by the beam at the source.
