I would have guess at Hamble Yacht Services first off. I was there for a week or so living on board and every morning or sometimes at dead of night a transporter from med wd turn up and sometimes they wd crane the boat off in the morning, sometimes not. HYC have a v large crane so they could defintely handle anything hence reasonable guess for any numptie driver. You could just ring round of course - there ain't too many marinas that can handle a 40 footer off a lorry.
