I have had problems at the Scarbie ramp (next to the Coast Guard), I had an attempted steal of my jet ski and trailer but saw the guy, we chased and got it back (see my story in Lost Stolen menu) - I now have locks on the trailer for boat and ski, both are insured but you only get 80% back if no lock on the trailer.
I think they need a camera at that ramp, donate one to the coast guard and have it set up on the car park.
