What year would hull # 4663 be ?

Enter your entire 12-digit HIN at this website: hindecoder.com. The HIN can be found in the upper right corner of the transom. The format is MMM-HHHHH-MM-YY, where MMM is the Manufacturer ID (CPS fpr Capri Sailboats), HHHHH is the Hull ID Number, yours might be something like D4663, MM is the month and year of production (using letter A - L for the month and a single digit for the year), and YY is the model year. My HIN 3486 was built in 1990.
