Navagear has a post that might be of interest to our US based readers (and potential visitors to the US). The Department of Homeland Security has been meeting with the boating "community" and is formulating plans for more boating oversite and ways for boaters to report potential security issues, etc.

All-in-all I don't know how I feel about it, but Navagear has some good commentary and a beginning discussion over there that you might want to follow (or jump in to).
