   CHAPTER I--COAST GUARD, DEPARTMENT OF HOMELAND SECURITY (CONTINUED)
 
PART 164_NAVIGATION SAFETY REGULATIONS--Table of Contents
 
Sec. 164.46  Automatic Identification System (AIS).

    (a) The following vessels must have a properly installed, 
operational, type approved AIS as of the date specified:
    (1) Self-propelled vessels of 65 feet or more in length, other than 
passenger and fishing vessels, in commercial service and on an 
international voyage, not later than December 31, 2004.
    (2) Notwithstanding paragraph (a)(1) of this section, the following, 
self-propelled vessels, that are on an international voyage must also 
comply with SOLAS, as amended, Chapter V, regulation 19.2.1.6, 19.2.4, 
and 19.2.3.5 or 19.2.5.1 as appropriate (Incorporated by reference, see 
Sec. 164.03):
    (i) Passenger vessels, of 150 gross tonnage or more, not later than 
July 1, 2003;
    (ii) Tankers, regardless of tonnage, not later than the first safety 
survey for safety equipment on or after July 1, 2003;
    (iii) Vessels, other than passenger vessels or tankers, of 50,000 
gross tonnage or more, not later than July 1, 2004; and
    (iv) Vessels, other than passenger vessels or tankers, of 300 gross 
tonnage or more but less than 50,000 gross tonnage, not later than the 
first safety survey for safety equipment on or after July 1, 2004, but 
no later than December 31, 2004.
    (3) Notwithstanding paragraphs (a)(1) and (a)(2) of this section, 
the following vessels, when navigating an area denoted in table 
161.12(c) of Sec. 161.12 of this chapter, not later than December 31, 
2004:
    (i) Self-propelled vessels of 65 feet or more in length, other than

    (iii) Passenger vessels certificated to carry more than 150 
passengers-for-hire.

    Note to Sec. 164.46(a): ``Properly installed'' refers to an 
installation using the guidelines set forth in IMO SN/Circ.227 
(incorporated by reference, see Sec. 164.03). Not all AIS units are 
able to broadcast position, course, and speed without the input of an 
external positioning device (e.g. dGPS); the use of other external 
devices (e.g. transmitting heading device, gyro, rate of turn indicator) 
is highly recommended, however, not required except as stated in Sec. 
164.46(a)(2). ``Type approved'' refers to an approval by an IMO 
recognized Administration as to comply with IMO Resolution MSC.74(69), 
ITU-R Recommendation M.1371-1, and IEC 61993-2 (Incorporated by 
reference, see Sec. 164.03). ``Length'' refers to ``registered length'' 
as defined in 46 CFR part 69. ``Gross tonnage'' refers to tonnage as 
defined under the International Convention on Tonnage Measurement of 
Ships, 1969.

    (b) The requirements for Vessel Bridge-to-Bridge radiotelephones in 
Sec. Sec. 26.04(a) and (c), 26.05, 26.06 and 26.07 of this chapter also 
apply to AIS. The term ``effective operating condition'' used in Sec. 
26.06 of this chapter includes accurate input and upkeep of AIS data 
fields.
    (c) The use of a portable AIS is permissible only to the extent that 
electromagnetic interference does not affect the proper function of 
existing navigation and communication equipment on board and such that 
only one AIS unit may be in operation at any one time.
    (d) The AIS Pilot Plug, on each vessel over 1,600 gross tons on an 
international voyage, must be available for pilot use, easily accessible 
from the primary conning position of the vessel, and near a 120 Volt, AC 
power, 3-prong receptacle.
