Thanks guys, It's just a case of trying to get as many people as possible looking out for it, turns out to add insult to injury the insurance had just lapsed and I didn't realise! As has been said, if at all possible remove as much as you can from your own boats, I had the Insurance approved Yam lock fitted, had the engine chained to a floor fixed post and had the whole transom reinforced with a stainless steel plate and still they took everything - NOTHING IS SAFE regardless of how secure you think it you have made it!! I think with everything I will now leave the boating world so if anybody knows of anyone that wants to buy a yorkshire pebble on a trailer give me a shout!
