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 hull intersects the surface of the water.
In ISO 8666 for small boats, there is a definition of LOH, or length of hull. [9] This may be shorter than a vessel's LOA, because it excludes other parts attached to the hull, such as bowsprits . LWL
The Skipper 17 is a classic sailboat designed by Peter Milne and first built in 1966 by Anderson, Rigden & Perkins/Richmond Marine in the UK. This centerboard (trunk) sailboat has a fractional sloop rigging and measures 17.00 ft in length overall (LOA) and 6.42 ft in beam, with a displacement of 700.00 lb.
Beam diameter is usually used to characterize electromagnetic beams in the optical regime, and occasionally in the microwave regime, that is, cases in which the aperture from which the beam emerges is very large with respect to the wavelength. Beam diameter usually refers to a beam of circular cross section, but not necessarily so.

Engineering fits are generally used as part of geometric dimensioning and tolerancing when a part or assembly is designed. In engineering terms, the "fit" is the clearance between two mating parts, and the size of this clearance determines whether the parts can, at one end of the spectrum, move or rotate independently from each other or, at the other end, are temporarily or permanently joined.
where I is the moment of inertia of the beam cross-section and c is the distance of the top of the beam from the neutral axis (see beam theory for more details). For a beam of cross-sectional area a and height h , the ideal cross-section would have half the area at a distance h / 2 above the cross-section and the other half at a ...
