・All VTS Users (Both full and passive participants) navigating in Los Angeles Harbor.
・All VTS Users (Both full and passive participants) navigating in Long Beach Harbor.
・All vessels greater than 1600 tons when anchored in Los Angeles or Long Beach Harbor.
What vessels are subject to the “VESSEL BRIDGE TO BRIDGE RADIOTELEPHONE ACT”?
1) Every power-driven vessel of 20 meters or over in length while navigating;
2) Every vessel of 100 gross tons and upward carrying one or more passengers for hire while navigating;
3) Every towing vessel of 26 feet or over in length while navigating; and
4) Every dredge and floating plant engaged in or near a channel or fairway in operations likely to restrict or affect navigation of other vessels except for an unmanned or intermittently manned floating plant under the control of a dredge.
USCP 7, Ch. 2, ¶ 510 to 513
What radio equipment are vessels required to carry under the “VESSEL BRIDGE TO BRIDGE RADIOTELEPHONE ACT”?
