N.B. If you are uncertain of the precise details for the
specification, give the manufacturer full details of the vessel, method and
intended use and let him suggest the particular size. Much money and time is
wasted foolishly specifying much too large a unit, e.g. '10 ton' winch or '100 mesh deep'
gillnet.
