Well ... there's good news and bad news. The good news is that you can read the year of manufacture from the serial number. The last two digits are the year.
CCML1944A888 ( CCM L 1944 A 8 88 )
CCM - Coast Catamaran Manufacturer
L - The letter in that position "L" stands for the model of boat/kayak. Each boat model (H16, H17, H18 etc.) starts out with a different letter. If more than 9,999 of that model were built in one year, there would be multiple letters for a single model. In example, there were so many Hobie 16's built in some years that the model letters include CCMB, D, E, F, L, O, P R and S (also do to several other factors). The letter must change if we build more than 9,999 in one year.
1944 - Serial number sequence number
A - "A" is the month for January, "B" February and so on.
8 - year which was built in 1988
88- This boat is a 1988 model year. Model years are like cars. The new year starts in September.
The bad news is that it's engraved on the crossmember, front I think, and you have to disassemble the boat to find it. Not easy to convince a seller to try.
