As to answer your question this is what was sent to me.
This is complements of "Mic Healey" <mic@...> in an old email:
As far as the year of your boat - you can use this list:
CLASSIC JAVELIN PRODUCTION HISTORY
YEAR PRODUCED CLASS NUMBERS
1963 1 - 92
1964 93 - 256
1965 257 - 437
1966 438 - 818
1967 819 - 1147
1968 1148 - 1414
1969 1415 - 1728
1970 1729 - 2053
1971 2054 - 2261
1972 2262 - 2376
-Looks like you have a 1971 (final year) model.
The hull number would seem to be the serial of ALL ODAY MODELS produced.
The class number is the number of Javelins produced.
The number on the sail should be the CLASS NUMBER, which would be the number
of your Javelin.
(Look on your boat and see if there is a plate with a HULL number and a CLASS
If this is accurate then you appear to have a 1971 model.
I just got a Javelin and was wondering if anyone can tell me how I can find out what year it was made. I forget what the Hull Number was (I'm at work, the boats at home) but the model number is 2085. And is there anywhere you can download a users manual.
