Help with hull #

Can anyone help me to clarify what I'm seeing? #'s on starboard hull read: U.S. NACH06101900.

Thanks!
last two numbers are usually the production year, so i'm guessing your is a 2000 model, if it's a 5.5 uni then the following link is where i got this info, third reply with a list of id #s and model. hope this helps.
