Let's see if I can remember this...

CCMC02S4A585

CCM = Coast Cat Manufacturer
C = Model - TheMightyHobie18
02S4 = serial number of boat. Although I'd bet if we looked at the transom, that "S" is really a "5"
A = Month of manufacture, January
585 = year of manufacture and model year. Built in 1985 and is an '85 model. Model year begins in July.

Think thats it.
