[quote=DamonLinkous][quote=nacraman57]The last 4 digits indicate week?, month? and year of manufacture.[/quote]
The last THREE digits of the HIN (hull id number) indicate the year of manufacture and model year.
HIN's only started being required in the USA in 1972, from then to 1984 the format was first two digits were the model year and last character was a letter indicating what month it was actually manufactured. The manufacture year code started with A for August (of the previous year), so a boat with last three of 82A would be an 82 model built in August of 1981.
After 1984 the format was like the example in the original post, three number which represent the model and date of manufacture so a 787 boat is a 1987 model also built in 1987. If it had 687 it would still be a 1987 model but built in 1986.
