  1. Beam

    The beam of a ship is its width at the widest point as measured at the ship's nominal waterline. Generally speaking, the wider the beam of a ship, the more initial stability it has, at expense of reserve stability in the event of a capsize, where more energy is required to right the vessel from its inverted position. Typical length-to-beam ratios for small sailboats are from 2:1 to 5:1. Large ships have widely varying beam ratios, some as large as 20:1. Rowing shells designed for flatwater racing may have length to beam ratios as high as 30:1, while a coracle has a ratio of almost 1:1 - it is nearly circular. The beam of many monohull yachts can be calculated using the following formula: LOA is Length Overall. All units are in feet. Some examples - For a standard 27' yacht: the cube root of 27 is 3, 3 squared is 9 plus 1 = 10. The beam of many 27' monohulls is 10'. - For a Volvo Open 70 yacht: 70.5 to the power of 2/3 = 17 plus 1 = 18. The beam is often around 18'. - For a 741' long ship: the cube root is 9, and 9 squared is 81, plus 1. The beam will usually be around 82' e.g. Seawaymax.
