Fisheries Regulations 1992

A licensee shall cause a vessel registered in respect of his or her licence, other than a vessel referred to in subregulation (2), to be marked in the following manner:

the registration number shall be painted, on a yellow background in black arabic numerals of the size and height listed in the Table to this regulation, on both sides of the bow of the vessel as high as practicable above the waterline, and, where a vessel has a wheelhouse or foredeck, on top of the wheelhouse or foredeck, so as to enable the unobscured view of the number from the sea and the air; and

if the vessel has a superstructure or deck, the registration number shall be painted on a yellow background in lettering of a size enabling recognition, without the aid of optical equipment, on a horizontal plane from a distance of 250 m.

Where a vessel has an international radio call-sign, the licensee shall cause the call sign number to be painted on the vessel in black on a white background, or white on a black background, in numbers of the size and height listed in the Table to this regulation.

A person shall not make or retain on a vessel a marking which impedes the accurate recognition of the correct registration number or call sign number.
