The XXXL is a 148x46 cm board with 12mm rocker and is 44cm wide in the tips. This board is a great learning board for bigger guys from 10 to 15 knots.
The primary difference of the XXXL from the Glide is that it varies in outline mainly at its tips. The Glide tapers to approximately 38 cm at its tips (depending where you decide to measure), I measured between the two fin holes. The XXXL has minimal taper, hence the rectanglur look.
I view the XXXL as being just as how it sounds. It's the big boy's Glide at a great price, too. (gotta call)
It points upwind a little better than the Glide in the really light stuff and is less squirrelly in 13+ for average riders. In lots of ways, the Glide is a technical board to ride and beginners can sometimes struggle with it, especially when becoming powered up.
The XXXL is a "hop on it and go" light wind board for a beginner above 150 and a great light wind board for big boys.
For better riders, they will notice the XXXL is a little slower than the Glide.
I wouldn't want to race Pat on a Glide if I was on the XXXL. (Come to think of it, don't want to race and lose to him, period!)
The speed difference is really only noticeable at 13+ knots. But I felt the board "topped out" in speed before the glide. Maybe I just imagined it, but I don't think so.
The Crazy Fly 145 by 44 is also a great first time board for a guy between 150 to 190. I nicknamed the CF 145 the mini-glide.
I guess the XXXL could be nick-named the magna-Glide.
Oh, no concave on the XXXL. Concave is a light wind board's enemy
