They are the same width as the Boyer "Flyer" A class boards I have been using in my Mossie for the last 4 years, 8 inches.

Why I am interested in trying these maximum (Mossie rule) length boards is that the "Flyer" boards I have been using are shorter under the Mossie than the A class, as the hull of the Mossie is deeper than the A class so less sticks out. So it's possible they have been a bit too small, these new boards (now available from JK Fibreglass) are the other extreme, so I am keen to find out if you can feel any difference when sailing, better pointing, more lift etc. And are there any down sides?

Hopefully find out this weekend .
