from "USCG AIS frequently asked questions" site

"6. When must AIS be in operation? Vessels equipped with AIS (either by mandatory carriage or voluntarily) must abide by the requirements set forth in 33 CFR 164.46(d) and should especially ensure their AIS is in properly installed, using an assigned MMSI, and, that its data is accessible from the primary conning position of the vessel. Also, that it be in 'effective operating condition', which entails the continuous operation of AIS and the accurate input and upkeep of AIS data fields during all times that the vessel is navigating (underway or at anchor), and, at least 15 minutes prior to unmooring. Should continual operation of AIS compromise the safety or security of the vessel or where a security incident is imminent, the AIS may be switched off. This action and the reason for taking it must be reported to the nearest U.S. Captain of the Port or Vessel Traffic Center and recorded in the ship's logbook. The AIS should return to continuous operation as soon as the source of danger has been mitigated."
