I'm installing a GOST Nav-Tracker system today, and this is a piece of cake technically. Doing it well however takes some ingenuity. What we're doing is trying to outwit the thief that wants to steal your boat. For many whose boats are considered statistically attractive to those employed in the marine vessel purloin profession your insurance carrier will mandate one of these system.
The ingenuity comes into play because you have to do your best to hide these systems from an experienced filcher. Sometimes this is fairly easy to do, and sometimes not so much. My sense is that the experience thief wants to get the boat out on the water as quickly as possible. Once well clear of the dock they will start to hunt for it. Using the phrase "my sense is" is not to imply I have any actual experience in heisting a boat, but merely an extrapolation of how I would go about it. These pictures have been severely redacted to insure the locations of these pieces and the type of boat are not divulged.
