Common use of COMMUNICATIONS PROCEDURES Clause in Contracts

COMMUNICATIONS PROCEDURES. (1) Upon being approached by a USCG ves- sel or aircraft, or other vessel or air- craft with an authorized officer aboard, the operator of any FFV subject to this subpart must be alert for communica- tions conveying enforcement instruc- tions. The enforcement unit may com- municate by channel 16 VHF-FM radio- telephone, 2182 kHz (SSB) radio- telephone, message block from an air- craft, flashing light or flag signals from the International Code of Signals, hand signal, placard, loudhailer, or other appropriate means. The following signals, extracted from the Inter- national Code of Signals, are among those that may be used. (i) ‘‘AA, AA, AA, etc.’’, which is the call for an unknown station. The sig- naled vessel should respond by identi- fying itself or by illuminating the ves- sel identification required by § 600.505. (ii) ‘‘RY-CY’’, meaning ‘‘You should proceed at slow speed, a boat is coming to you’’. (iii) ‘‘SQ3’’, meaning ‘‘You should stop or heave to; I am going to board you’’. (iv) ‘‘L’’, meaning ‘‘You should stop your vessel instantly.’’ (2) Failure of an FFV’s operator to stop the vessel when directed to do so by an authorized officer using VHF-FM radiotelephone (channel 16), 2182 kHz (SSB) radiotelephone (where required), message block from an aircraft, flash- ing light signal, flaghoist, or loudhailer constitutes a violation of this subpart. (3) The operator of or any person aboard an FFV who does not under- stand a signal from an enforcement unit and who is unable to obtain clari- fication by radiotelephone or other means must consider the signal to be a command to stop the FFV instantly.
