im on the verge of buying a used boat that would be getting delivered from Yorkshire. the woman said its older than 1972 and it do's not have a hull number or a name so i'm wondering how to go about buying it, also can anyone guide me on checking the engine serial number as well i have it here if any one can help get posting please. there was one peace of information she offered and that was this "SAND MARTIN 3D PLUS MARINE.................. SO YOUR GUESS IS AS GOOD AS OURS - IF YOU CAN FIND ANYTHING ON WELL............" her husband had a look that was after i asked for the hull number but she said its older than 1972. how can i protect myself and be able to reclaim my money if its stolen something like a affidavit...
