The only info I have is from an old catalog I received from Ted Bell some time back in the early 1980s. At that time the line-up was pretty limited with the CJ Solo, the Merlin, and the Traveler III described in the 4 page catalog (which was a single piece of monochrome brown "construction paper" and the Creek Runner, Fusion, Dynamic WWOC-1, and the North Bay Cruiser described in some typewritten paper pages included.
At that time the standard construction for Bell boats was S 'glass exterior/Kevlar interior with almond gel coat, cane seats, and white ash rails and thwarts with black walnut deck plates.
The info given for the Merlin is as follows:
Designer Bruce Kunz
length overall 15 1/2'
gunnel width (outrail to outrail) 27"
depth B/C/S 15 1/2" 11 1/2" 14 1/2"
You should be able to figure out the year of production of your boat from the HIN. Perhaps Charlie Wilson knows how many were produced.
