Huh?
Jeanne gave his (her?) hull number as ERY3827E989, which confuses me. My manual says that ERY is of course for Ericson, the next two numbers (38), are for the model, and the following THREE numbers are the hull number. Following the hull number is a letter that corresponds to the month of manufacture, the first of the three final numbers is the last digit of the calander years in which the boat was built, and the last two numbers are the model year.
So my boat was an Ericson 38, hull 318, built in March of 1989. But what is Jeanne's boat? If there is a number missing, and it is actually ERY38327E989 it would make sense as being hull 327 built in May of 1989. If not, then it looks as if they started a new numbering system sometime after March in 1989.
