Avanti Mach 5 water ski. Length is about 66 inches, maximum width is 7 inches.

I don't water ski, but this looks in very good condition. One small chip on the top front, see picture.

This one has some adjustment (click on the first picture).

I can not get my size 9-1/2 Med Width foot in it. It is not wide enough and appears to be too short.
