Oh my, FWC will confiscate your boat if you ever get stopped and checked!
OK, just kidding, Hull ID's were not required by law until 1974 !
My 1970 did not have one either...
What I would do is go to an engraving shop and have two made with
the number that is used on the title... One for the starboard corner
and one to put in a hidden location...
