Boat security over the web

Several GPS trackers here http://dx.com/s/gps+tracker.html?category=717

I have this one http://dx.com/p/gps-dualband-gsm-realtime-spy-anti-theft-vehicle-tracker-22968?item=9

bonus is internal battery which keeps for a few days if external power is lost

Many thanks for looking dmayes!!
They look good thanks testmonkey but they all seem to be just trackers which is not my main interest.

Some of the trackers are clones which don't work as well - someone over on RIB.NET has done a lot of research on which is which, I'm sure it will come up on a search.
