There is a very scruffy one sat in Haslar Marina, might belong to the marina itself. Tubes gone flat and deck needs painting but it looks complete which would save a major headache, Has a new console and engine box which look serviceable. make them an offer, you never know. Regards Pete
They featured several RIB's for disposal on their site in April this year, and it might be worth checking to see if they are all spoken for. They are all in varying states of repair, some with engines some without. Tube wise, I can give you a price for a new set if required.
