I was chatting to a guy on a pontoon in Fowey last summer who told me heíd had the engine taken from his RIB. The boat was in winter storage in a boat yard in Fowey (not sure which one, but it was not Penmarlam). The thieves used a chainsaw to cut the transom out.
I was also stopped by the police late last year towing my RIB near Bodmin. They said there had been a number of RIBs stolen from Rock Marine Services recently so they were checking the ownership of any RIBs they came across being towed.
I donít know what the answer is to this, but itís obviously a widespread problem. Considering how expensive boat storage is I think you should be able to expect half decent security on the premises. I thought Penmarlam was fairly secure but I guess thatís not the case.
