Here are the budget Correct Crafts that have heard have good wakes:
Smooth Super Air type hulls:
----------------------------
82-89 Ski Nautique 2001
93-97 Sport Nautique
98- Sport Nautique (some say not as good as 93-97)
96?- Super Sport
Straked hulls with more deadrise:
---------------------------------
87?-90 Barefoot Nautique
91-94? Barefoot Nautique (v-drive)
91-94? Excel (v-drive)
92 Sport Nautique (less deadrise than others)
Oddball hull (strakes, low deadrise, vents, etc.)
------------
99-02 Pro Air Nautique (heard conflicting reviews)
I've heard bad things about the TSC hulls (for wakeboarding, obviously). The TSC2 hulls (newer) are supposed to be better. I honestly haven't heard anything about the wakes on the post-2001/pre-TSC (1990-1996) Ski Nautiques.
You can look at the brochures from most years here:
