VTS San Francisco cannot alert vessels about minimum wake requests during VCRP.
Vessels must know the federal and state regulations pertaining to vessel wake.
Refer to the US Coast Guard Navigation Center webpage for more information on vessel wake regulations.
During VCRP, vessels requesting a minimum wake must alert approaching vessels on their own.
To alert approaching vessels, minimum wake requesters should make radiotelephone reports in the blind, on the VTS designated radiotelephone channel.
Minimum wake requesters should make a Safety signal broadcast (SSB) as described in 47 USC 80.1109 (b) and (c) - Distress, urgency, and safety communications. Most mariners know the safety signal broadcast as the “SÉCURITÉ call.”
Consider the number and types of vessels typically transiting through the area when deciding how often to make the Safety Signal Broadcast.
Refer to published schedules and routes for commuter ferries and other similar vessels.
Here is an example minimum wake Safety Signal Broadcast. Customize the broadcast to meet your needs.
"SÉCURITÉ, SÉCURITÉ, SÉCURITÉ
ALL STATIONS, ALL STATIONS, ALL STATIONS
THIS IS THE TUG ABC.
We are at Oakland 56 with a barge moored alongside the container ship XYZ, bunkering. Request a minimum wake from passing vessels. Concerned vessels contact tug ABC on VHF FM Channel 13."
