J/35 Class Association

From the old forums.

Once you find the number on the hull, you need the secret decoder ring to pick the hull number out of it.  My number is:

  TPS50257C989

Which translates to:

TPS = manufacturer (Tillotson Pearson or TPI in my case)
50 = model number, 50 standing for J35.
257 = hull number, the piece you're looking for.
C = month of the year it was built, A = January.
9 = certification year, last digit only (so 1989 in my case)
89 = year of manufacture, also 1989 in my case.
