Hi Mart,
I would concur with Ian, insurance on high speed boats is a must. Your boat handling skills might be good but accidents do happen, if there was a failure of any type with the receiver, transmitter, boat, you took ill, fell over etc. I hit a buoy with mine and it travelled some 20 feet before stopping. Even the experts loose it (not me obviously). Water is not controlable. I saw 1 go over a bank on Sunday into the road and when testing at Brentwood twice they ended up on the banks.
There is a limited liability on damage to property etc. Personal liability insurance is running at the £5,000,000 to £10,000,000. We live in an age of ambulance chasers and litigation. I would not want to be the one to test the case, and or bring the hobby into disrepute or even get them band by the green welly brigade! I think loss of a finger is running at about 10k at the moment. It only takes a kid sticking his hand in?
Contact the OMRA secretary for clarification, its a small price to pay for peace of mind.
Regards
Simon
