Hull numbering system

Post by Jim Tanner »

Can anyone explain the hull numbering system to me. I have a 1977
Cape Dory 27 Hull # 65. I see where someone has a 78 with a
smaller number. Really enjoy this site.

the generic hull identification number for a cape dory is:

CPDXXXXYY where YY is the year manufactured and XXXX is the hull number. The ID is usually located on the transom, outside starboard side.

Check out the following website for very general information on the hull numbering system.

Your CD hull ID number should contain the manufactures ID code, a number indicating how many hulls have been manufactured up to and including yours and the date of manufacturer. The date is coded with the month being indicated by a letter of equal numeric value. ie January=a, September=i, etc.

I believe the law which required hull numbering did not exist prior to the late 70's. This is why you can find many boats with no "hull numbers" on them at all. It would be interesting to find out if your CD boat numbering system reflected a different meaning such as the number of the boat built that year, etc or some other identification sytem. Just throwing out a thought. I think that before the law, it may have been up to the manufacturer what "system" was used. Let's see if anyone else can shed some light on this.
