Hi Jake,
C4 shafts are available but unfortunately

you have to buy the blade and handle as well as they come as a package and that is life. To snap a carbon shaft by hitting the rail whilst surfing is hard to believe

whether it be a C4, Werner or whatever brand of shaft. Could you give everyone more information on how it happened?
If you want one in a hurry pop into Dale Chapmans factory as he is making some excellent shafts at the moment and I'm sure he would be more than willing to help you get back on the water and the same could be said for Woogie & Jodie with their paddles.
