There are a couple guys who hang out in news:alt.security.alarms who have
done some really comprehensive boat alarms including monitoring using
cellular communications designed for alarm purposes.

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?")
