I am at least the third owner of a 1971 P26. My NYS Reg says 1971 so that's why I say 1971. The oval disc with the Pearson logo and hull number that is mounted to the engine well was long gone when I got the boat 12 years ago. I have been through the boat from stem to stern many times and have never found any numbers. Does anyone know if there is any obscure place on a P26 where the hull number is located?
