We have had a number of boats stolen recently. The thieves (about 4 in a small boat) come in small boats at night (preferably during a rainstorm) and swim or paddle the boat out, then tow it to where they are far enough to start the boat, to be taken to a quiet hidden place where they remove the engine. It has been reported that they hide under the dock.

What can you do against Boat Thefts:

Keep the boat area lighted and have someone watch the boat at night.
Flashing light on them makes the thieves move on.
I would not recommend to confront the thieves as they may be armed.
Captain Sharks (226-3370) sell engine locks with steel cable / chain, to lock the engine to the dock.
You can remove the main breaker from the engine, so it can't be started.
Amazon sells these [u]Satellite Based Boat Monitoring & Theft Systems[/u] for US$292.93 but don't ship them to Belize.
A reward has been offered for the arrest and conviction of these thieves by neighbours, we will keep you informed about this.
