|Also check that the boat is a LE not an SE, you will know this by the rudders being white gel coat and not plastic. The shrouds and trap wires will also be plastic covered, the tramp will be mesh and the main blocks will be Harken and not sail speed.
You also want to get a boat after the tracks on the beams were changed to internal and not external. This happened at about 1992. Good way to check for a complete boat instead of bits of boats.
Lastly, you can check the age of the boat by a little aluminium plate in the middle of the back beam.
