How wide is a 11'2 Tabou crossover?
Yep, thats the important point. For a 6ft beginner, at least 32" wide is important to speed the learning curve.
On the web I see that at least 2 widths for the crossover: 30" and 32", so it is important to know the width.
Note that the crossover can be windsurfed too: it may add a little weight but can be quite fun if your boyfriend - or you - windsurfs or want to learn it someday. And it will be easier to resell I guess.
