How can I cross reference a hull serial #

[McGillicuddy]

3 letters represent Mfg. SEC for Potters Seacrafts
1 letter or perhaps number for model
1 number for length (e.g., 3 for 23'
3 numbers for hull id
4 numbers for month and year of manufacture

Here's an example using my my old '78 SeaCraft Seavette 23:
SEC V 3 013 1178
