Kurt, you're assuming Pearson stopped production on 01/01/67.

Consider 62=1, 63=2, 64=3, 65=4, 66=5, and 67=6.

440 boats / 6 years = 73 per year, and 440 - 73 = 367.

Soooo, Hull #368 was the first hull of 1967... ??? Yes, very rough, but it would seem to point to our little boats being a 1967 vintage, don't ya think?
