Info from the US Coast Guard

The 1000 yard security zones around San Francisco and Oakland International Airports are still in effect. These zones are now clearly marked by white/international orange informational buoys. Hopefully, this will reduce the number of boaters who unintentionally enter the restricted zone.

The Coast Guard continues security patrols and active vessel escorts amongst other activities dealing with Port Security in and around most port facilities in the San Francisco Bay area. For those of you continuing to sail/motor through the winter season, we request your assistance in monitoring activities out on the water and around your moorings. Places of particular interest we ask you to keep an eye on
include near or around:

* Bridges 
* Entrances to tunnels
* Power plants 
* Water intakes 
* Oil facilities
* Chemical facilities
* Fuel docks 
* Military bases

What boaters should look for:

* Fishing or hunting locations not typically used for fishing or hunting
* Unattended vessels
* Unusual boat characteristics
* Any aggressive activities
* Unusual filming activities
* Unusual diving operations
* Recovering or tossing items into or onto the water or shoreline
* Unusual number of people on board
* Lights flashing between boats and shore at night
* Frequent trips between some of the above points of interest

Please continue to report any unusual or suspicious activity to the Coast Guard via telephone (415-399-3451) or VHF radio or simply contact 9-1-1. The reports you make may save your life or many in the area and could be the key piece of the puzzle to fight terrorism in our waters.
