data on the armament, machinery, complement, etc., but its statement on the main
dimensions, possibly because of the security constraints placed on such data by
navies, does not give the figures that a naval architect would like to have.
The length LOA and the length LWL always used to be given, but some recent
entries only give LOA. The breadth is given but for ships with flared sides this is
usually the maximum beam and not that on the LWL which is what a naval
architect is mainly interested in. For some inexplicable reason the depth is never
