I saw a board over the weekend made from this stuff. It was the lightest board I've ever felt, with 1x4 oz. glass, top and bottom. The shaper said that you must connect fin boxes to the deck somehow for strength. He therefore used FCS, but I guess you could use other means for reinforcing other fin systems.
Ah yes... the glass thing is confusing: I do understand they are supposed to be glassed, but there is a promo video of machado and burch riding just the blanks out at cardiff... looks like that yard possum stuff.
I emailed marko with some questions of course. The local distributor indicates they can get them.
saw it at the sacred craft show, i think the marko rep said it must be done on a machine because it does not hand shape well. the raw blank looked just like my boogie board core.
