I was friendly with a guy called "Reg" about 10 years ago .He was living on an old Bermudan cutter called "Pedorma". I know he refitted the boat and lived aboard in Bristol for a few years but lost track of him after that.
Ages ago there was a posting about a site (maybe Ofcom) where you could type in boat name and it came up with a few details and i think location. Someone will know the link. Not seen that boat in cardiff or other severn harbours recently though.
