1977sc hidden hull id?

[APL]

My '73 doesent have a hidden HIN. I currently have it down to the stringers. I believe that some time around the 1986 model year a hidden HIN became mandatory. For instance my 1983 Boston whaler only has the standard HIN however my 1988 Boston whaler has a 2nd HIN under the front hatch.

I hope this helps.
