§ 300.108 Vessel and gear identification. ( a ) *Vessel identification.* ( 1 ) A vessel issued a permit under this subpart must be marked with the vessel's name and its International Radio Call Sign (IRCS) amidships on both the port and starboard sides of the superstructure or hull, so that it is visible at all times from an enforcement or inspection vessel. Fixtures inclined at an angle to the vessel's side or superstructure would be considered as suitable provided that the angle of inclination would not prevent sighting of the IRCS from another vessel or from the air. The vessel's IRCS shall also be marked on the deck. Should an awning or other temporary cover be placed so as to obscure the mark on the deck, the awning or cover shall also be marked with the IRCS. The marks should be placed athwartship with the top of the numbers or letters towards the bow.
( 2 ) Boats, skiffs and craft carried by the vessel for fishing operations shall bear the same mark as the vessel, except that a numerical suffix specific for the boat, skiff, or craft must follow the IRCS.
( 3 ) The vessel identification must be in a color in contrast to the background and must be permanently affixed to the vessel in block Roman alphabet letters and Arabic numerals using good quality marine paints. The letters and numbers shall be: At least 1 meter in height (h) for the IRCS placed on the hull, superstructure and/or inclined surfaces and at least 0.3 meter for marks placed on deck. The length of the hyphen shall be half the height of the letters and numbers. The width of the stroke for all letters, numbers and the hyphen shall be h/6. The space between letters and/or numbers shall not exceed h/4 nor be less than h/6. The space between adjacent letters having sloping sides (*e.g.,* A and V) shall not exceed h/8 nor be less than h/10. If a contrasting color is used for the background of the marks, it shall extend to provide a border around the mark of at least h/6.
( 4 ) The marks and the background shall be maintained in good condition at all times.
( b ) *Navigational lights and shapes.* Each vessel issued a vessel permit must display the lights and shapes prescribed by the International Regulations for Preventing Collisions at Sea, 1972 (TIAS 8587, and 1981 amendment TIAS 10672), for the activity in which the harvesting vessel is engaged (as described at 33 CFR part 81).
( c ) *Gear identification.* ( 1 ) The operator of each fishing vessel must ensure that all deployed fishing gear is clearly marked at all times at the surface with a buoy displaying the vessel identification of the harvesting vessel (see paragraph (a) of this section) to which the gear belongs, a light visible for 2 miles at night in good visibility, and a radio buoy.
( 2 ) The operator of each harvesting vessel must ensure that deployed longlines and strings of traps or pots, and gillnets are clearly marked at all times at the surface at each terminal end with a buoy displaying the vessel identification of the harvesting vessel to which the gear belongs (see paragraph (a) of this section), a light visible for 2 miles at night in good visibility, and a radio buoy.
( 3 ) Unmarked or incorrectly identified fishing gear may be considered abandoned and may be disposed of in accordance with applicable CCAMLR Conservation Measures in force with respect to the United States by any authorized officer or CCAMLR inspector.
( d ) *Maintenance.* The operator of each vessel issued a vessel permit must: ( 1 ) Keep the vessel and gear identification clearly legible and in good condition at all times;
( 2 ) Ensure that nothing on the vessel obstructs the view of the markings from an enforcement or inspection vessel or aircraft; and
( 3 ) Ensure that the proper navigational lights and shapes are displayed for the vessel's activity and are properly functioning.
