BP,
The Glide 14 and 17 are designed for Down Winders.
The Javalin 14 is designed for flat water racing, with minimal rocker and a cutting/piercing nose.
Ditto for the Catalina, 12'6.
And as PT said, nobody is too sure about the Glide 12, but DJ had a good time windsurfing it !!

I've heard the 12 surfs OK too. (I say "OK"). So the 12 might also be described as a bit of an accidental all rounder, surf, flat, cruise, race, windsurf, sight seeing.... Master of none ?
