The beam of a ship is its width at the widest point as measured at the ship's nominal waterline.The beam is a bearing projected at right-angles from the fore and aft line, outwards from the widest part of ship. Beam may also be used to define the maximum width of a ship's hull, or maximum width including superstructure overhangs.


The beam of a boat is the measurement of its width at its widest point. Many ship designs have a constant beam measurement that runs most of the length of the vessel, while others may have a more pronounced taper. Beam measurement is important for two reasons.


The widest part of a boat's width is its beam. Measuring the beam is a two-step process, because you must find your boat's centerline and make the measurement perpendicular to the centerline. All you need is a ball of twine, a carpenter's square, some duct tape and a measuring tape.


Beam can also be measured at specific points on the hull like the pilot house or cargo area but these measurements will be designated with the names of these structures. The main measurement of beam is taken at the widest point of a vessel.

Definitions. 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 perpendicular distance from the centerline of one hull ...


The beam is the width of the boat at its widest point.. If something is 'on the beam' it is to the side of the boat. Themore typical nautical expression for this is "abeam" for instance abuoy ...


To measure the beam at the waterline, you can extend a plumb-bob down to the water line. If the boat is wider above the waterline than at the waterline, you can measure the distance from the plumb-bob string to your hull at waterline with the help of a triangle to assure you measurement is perpendicular to the plumb-bob.


Thus, if you have a boat that is 50 feet on deck and 46 feet on waterline, the registered length will be 48 feet. The same holds true for the beam of the boat; it's an average between the widest point and the beam at water line. Tonnage
