Ship length to beam ratio

WebEven so the modern ballast keel yacht is still a relatively broad-beamed vessel, i.e. with a waterline length about 3 times longer than its beam - in technical terms, a length/beam ratio of 3:1. Beamy hulls of 3:1 have to push a lot of water around them when sailing. This produces the well-known drag waves. WebAug 25, 2000 · The beam to length ratio can be made up in several ways. I prefer to use the following formula: (LWL + LOA/2) / Max beam. Typically this number is around 5 for a 12 …

WebBritain had built two long frigates in 1858 – HMS Mersey and HMS Orlando – the longest, largest and most powerful single-decked wooden fighting ships. Although only 335 feet long, they suffered from the strain of their length, proving too weak to face a ship of the line in close quarters. [2] “HMS Mersey (1858).”.

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.
