Don't know anything about boat security, but car break-ins have been the norm in SXM ever since I have been going there. Don't like it, and it sure seems like to me that the SXM cops COULD get a handle on it if they wanted to, but apparently they don't. The resolution is never leave any thing in your car, at any place, at any time, for any length of time. Then there won't be anything stolen from it. As I said, I don't like it, but that's the facts.
