This thread reminds me of a similar enforcement effort at Braun Bay during the 2000 season.
For those interested, here's a link to the thread starter and some interesting reading from the OLD forum archives:
MP Invades Braun Bay
At the time I had many of the same questions I see posted in the current thread. What does happen when I'm at anchor and someone makes a raft closer than 50 feet to my boat? We are both in violation.
As for mooring balls:
Orange balls are
supposed to be in the NRZ in Braun Bay to mark the 75 foot distance from shore you can anchor - not to use as a mooring but to mark the distance. One year they had signs out at Braun Bay with the NRZ rules. I believe the signs were placed 75 feet from shore. The rules for the WAM area sandbar are a little different.
Somewhere around here I have a few pictures of a Marine Patrol boat on routine patrol passing close to NRZ violators in Wentworth Cove - not interested in NRZ enforcement.
