This was in the LNtM:

A 100-yard security zone is in place surrounding all cruise ships, tank vessels, or any other vessel that the U.S. Coast Guard deems to be a high interest vessel within San Francisco Bay, Monterey Bay and Humboldt Bay. A security zone is in place around all U.S. Naval Vessels greater than 100-feet in length within the navigable waters of the U.S. This permanent protection zone extends 100-yards around all naval vessels and it includes a 500-yard slow zone in which all mariners must operate at the minimum speed necessary. At the Golden Gate and Oakland/San Francisco Bay Bridges, a 25-yard security zone is in place around all bridge abutments and piers. For further details or comments contact the Sector Command Duty Officer at 415-399-3547.

AFAIK the regs are to not go within 500 yards at all;
nothing about going slow.


... Personally, I
don't want to get even that close. We go the other way.


One saving grace is that Navy ships are a *lot* more
maneuverable than similar sized commercial vessels. So you
don't have to be quite as paranoid about getting run down.

Years ago I was on the bridge of a Knox class frigate (long
since melted down for razor blades) entering Newport RI
harbor. It was very interesting to see how many small boats
& sailboats blundered along right in front of us, often
disappearing under the bow. Then again, at other ports we
occasionally had brushes with anti-nuke protestors who would
try to get us to run them down. So the exclusion zone is not
free of political tainting (surprise surprise).
