The Los Angeles and Long Beach Main Channels are considered Narrow Channels. Vessels less than 20m in length, sailing vessels, vessels engaged in fishing, or any other vessel attempting to cross these channels shall not impede a vessel that can only safely navigate within the narrow channel as per Inland Navigation Rules, Rule 9. To obtain information on the movements of vessels inside the federal breakwater contact the LA P/S on Ch 73 (156.675) ph 562-732-3805 or LB P/S Ch 74 (156.6) ph 562-432-0664.

Question 4

Note D

Answer 4

Traffic lanes and Pilot areas established at approaches to LA & LB Hbr are shown on charts 18746, 18740, & 18720.
The normal pilot operating areas are outlined by trapezoidal magenta bands. Mariners are advised to exercise extreme care in navigating within these areas. No vesssel may enter this area unless it is entering or departing the LA or LB main channels. Vessels shall pass directly through without stopping or loitering unless stopping is for taking a pilot.
To receive information regarding movement of vessels in the TSS and Precautionary Area contact the VTS. The working freq. for the VTS is Ch 14 (156.7) ph 310-832-6411 and call sign is “San Pedro Traffic”

Question 5

Note E

Answer 5

A Precautionary Area has been established in the LA/LB area. Large vessels are maneuvering to embark or disembark pilots and to enter or depart the TSS. It is recommended vessel proceed with extreme caution in the area. Vessel are prohibited from anchoring in the precautionary area except in designated anchorages (110.214 – see note A)

Question 6

Note G – Vessel Traffic Management System (VTMS)

Answer 6

The Vessel Traffic Service of LA-LB, jointly operated by the COTP and Marine Exchange, has been established within the approaches to San Pedro Bay. The working freq for the VTS is Ch. 14 (156.7) and call sign “San Pedro Traffic”. Upon entering the VTS area, within 25nm radius of Point Fermin (33-42.3n, 118-17.6w), all inbound vessels shall report on Ch. 14 their vessel name, call sign, position, course, speed, destination, eta to destination, and whether or not they’ll be taking a pilot. Outbound vessels shall report 15 min prior to reaching the breakwater. To obtain information on the movement of deep draft vessels inside the federal breakwater contact the LA P/S on Ch. 73 (156.675) ph 562-732-3805 or LB P/S on Ch. 74 (156.6) ph 562-432-0664.

Question 7

Note X

Answer 7

Within the 12nm Territorial Sea, established by Presidential Proclamation, some fed laws apply. The 3nm line previously identified as the outer limit of the territorial sea, is retained as it continues to depict the jurisdictional limit of other laws. The 9nm Natural Reserve Boundary off the Gulf Coast of FL, TX, and PR, and the 3nm elsewhere remain in most cases the inner limit of Federal Fisheries Jurisdiction and the outer limit of the states. The 24nm Contiguous Zone and the 200nm EEZ were established by Presidential Proclamation. Unless fixed by treaty or the US Supreme Court, these maritime limits are subject to modification.

Question 8

Anchorage Berths

Answer 8

The anchorage berths shown in green are for the convenience of the COTP and the port pilots. Anchorages outside the federal breakwater are assigned by the COTP through VTMS. Anchorages inside the federal breakwater are assigned by the applicable port pilot. The Delta Anchorages are for the use of the USN and the USCG for explosive loading.

Question 9

Cautions

Answer 9

Caution – Improved Channels shown by broken lines are subject to shoaling, particularly at the edges.

Caution – Temporary changes or defects in Aids to Navigation are not indicated on this chart. See Local Notice to Mariners.

Caution – Limitations on the use of radio signals as Aids to Marine Nav can be found in the USCG LL and Pub 117.
RDF bearings to commercial broadcasting stations are subject to error and should be used with caution. Station Positions are shown as:

Question 10

Caution – Submarine Pipelines and Cables

Answer 10

Charted submarine pipelines and submarine cables and submarine pipeline and cable areas are shown as:

Additional uncharted submarine pipelines and submarine cables may exist within the area of this chart.  Not all submarine pipelines and submarine cables are required to be buried, and those that were originally buried may have become exposed.  Mariners should use extreme caution when operating vessels in depths of water comparable to their draft in areas where pipelines and cables may exist, and when anchoring, dragging, and or trawling.
Covered wells may be marked by lighted or unlighted buoys.

Question 11

Warning/Radar Reflectors

Answer 11

Warning - The prudent mariner will not rely solely on any single aid to navigation, particularly on floating aids. See USCG LL and USCP for details.

Radar Reflectors have been placed on many floating aids to navigation. Individual radar reflector ID’s on these aids have been omitted from this chart.

Question 13

Aids to Navigation/Supplemental Information

Answer 13

Aids to Navigation – Consult USCG LL for supplemental information concerning aids to navigation.
