6 Powers of British sea-fishery officers in relation to fishing boats
1 For the purpose of enforcing article 3(1) or 3(2), or any equivalent provision in an order extending to any other part of the United Kingdom made for the purposes of implementing a specified Community provision, a British sea-fishery officer may exercise in relation to–
(a) any relevant British fishing boat wherever it may be; or
(b) any other fishing boat which is within relevant British fishery limits,
the powers conferred by paragraphs (2) to (4) of this article.
2 He may go on board the boat, with or without persons assigned to assist him in his duties, and may require the boat to stop and do anything else which will facilitate either the boarding of, or the disembarkation from, the boat.
3 He may require the attendance of the master and other persons on board the boat and may make any examination and inquiry which appears to him to be necessary for the purposes mentioned in paragraph (1) or (2) of this article and, in particular–
(a) may search for fish or fishing gear on the boat and may examine any fish on the boat and the equipment of the boat, including the fishing gear, and require persons on board the boat to do anything which appears to him to be necessary for facilitating the examination;
(b) may require any person on board the boat to produce any document relating to the boat, to any fishing operations or other operations ancillary thereto or to the persons on board which is in his custody or possession;
(c) for the purpose of ascertaining whether a relevant offence has been committed, may search the boat for any such document and may require any person on board the boat to do anything which appears to him to be necessary for facilitating the search including rendering all documents on the boat’s computer systems into a visible and legible form;
(d) inspect and take copies of any such document produced to him or found on board and, where any such document is kept by means of a computer, require it to be produced in a form in which it may be taken away; and
(e) where the boat is one in relation to which he has reason to suspect that a relevant offence has been committed, may seize and detain any such document produced to him or found on board for the purpose of enabling the document to be used as evidence in proceedings for the offence;
but nothing in sub-paragraph (e) above shall permit any document required by law to be carried on board the boat to be seized and detained except while the boat is detained in a port.
4 Where it appears to a British sea-fishery officer that a relevant offence has at any time been committed, he may–
(a) require the master of the boat in relation to which the offence took place to take, or may himself take, the boat and its crew to the port which appears to him to be the nearest convenient port; and
(b) detain or require the master to detain the boat in the port;
and where such an officer detains or requires the detention of a boat he shall serve on the master a notice in writing stating that the boat will be or is required to be detained until the notice is withdrawn by the service on the master of a further notice in writing signed by a British sea-fishery officer.
