If there's the potential to get a bike frame down to 300 grams one can only imagine the benefits for windsurfing.
I was just watching that. 
I immediately wondered if it was applicable to masts - not just masts of course.
It sounds like it should be.
Masts should be lighter because the epoxy graphene matrix is a lot lighter, stronger AND tougher.
It's a way off though according to that vid.
Head already make squash racquets with Grapheme. They are readily available and, supposedly, incredibly strong and lightweight. I have a 'heavy' one and it weighs 135grams.
