Burglar-intrusion alarms for boats
I've done a few alarm systems in funny places; I found that the worst thing
is false alarms, so now I use only simple and reliable switches, i.e. light beams and magnetic switches [no motion detectors]. but the thing I really like is the paging system with it's own transmitter [CB frequency]. works for about a half a mile. get it form auto radio and CB kind of shops. then you have the option for a silent alarm. we caught a guy with ours some years ago [there was some violence, noise, and then a three year prison term for him]. while sleeping on board, nothing beats a dog. a funny smell in your space rings in a canine head like a siren. my fuzzy little friends have saved us at least 4 times in the last 15 years. regards, Mark Holden "Kiyu" wrote in message ...

Obviously communications may not work when off the coast of some desert island in the middle of nowhere, but it works well when at your home anchorage. Although this isn't an alarm as such, more along the lines of intrusion prevention for foreign anchorages, while doing a Google search the other day I found where someone sells an electric fence charger/energizer for boat railings. With a bit of imagination I would think satisfactory electrical return paths could be worked out to allow use of a standard cattle unit. Certainly has a lot of appeal and beats Slocum's carpet tacks. The attempted intruder also acts as his own alarm as the YELP should be able to be heard for some distance. (judging from my own first encounter with an electric fence..."Now how bad can this be?")
