I first skied behind a 67 barracuda and then a 84 2001 before eventually purchasing my own boat(s). I agree with what others have said BUT, I would not buy a Pre 1993 nautique because of the severe rotting issues they have had. Their are countless threads on stringer/floor replacement of the 2001 hulls including the next generation following the 2001. The barefoot nautique and some other models did not go composite in 1993, I'm not sure of the year that all of the models went to a composite hull. Just be sure the model year your looking at is all glass, as they had severe problems with this issue.
I enjoy Reading many of the threads on CCF. The posters are very knowledgable and very willing to throw advise out to people.
