From what I can tell in those pics, they are 20 hulls strapped to a wide beam - and yes, I'm very interested in those boards.
Those are the banana boards used on the M20s, I would be surprised if they would actually use those though.
Maybe its because its early, but that does not look like a 3m beam to me.
Friend of mine sails a 3m wide Fox and you can easily tell the difference, but this does not look extra wide.
