people for some reason slum on the 90-96 Slant back nautique, not sure why? from I believe 93-96 they are no wood construction. Built like a tank, ski and drive amazing through 35 off. the 91-94 Prostar is likely a better all around slalom boat and more attractive but the slant back is an amazing boat.
I have an 01 TSC1 SN (bubble butt) and regularly ski a 96 with the same GT40 motor. I would definitely take a 95-96 Nautique over the same vintage Mastercraft or Malibu, but for sure the bubble butt is the cats ass of that vintage slalom boat.
people also slum the GT40 ford motor you most commonly find in the 95-01 Nautiques, unwarranted as well.
