I have been told by Avon that the last three numbers of your serial number tells you the age of your boat. e.g.
serial number ending in 387 would have been built in March 1987
&
Serial number ending in 692 would have been built in June 1992
I've had 3 SR4's now 1987, 1990 & 1992 and I have been wondering what other ages are out there, who has the newest and who has the oldest etc
