Apparently unlike the Navy, the USCG cutters transmit the AIS

AIS signal is no longer being transmitted. Makes sense due to being
shutdown while in port.

My experience with USCG cutters has been mixed, i.e., sometimes they
transmit, sometimes they don't. Too bad you didn't get to see them
going through the canal. That's an ideal viewing spot.
