There's a couple in the for sale in WA otherwise Simon at BC Qld is great at doing a deal. Few mates here have fanatics from him. Best to ring around to find the right board & price.
For North and Fanatic ..try Jay Sails wind surf and snow the zu board crazy surf fx dexter s sorry if i have missed anyone .. these are not in Wa but i'm sure happy to organize for you
Should test some Stone Surf Design and Severne boards first - boards that are built for the conditions you sail in, and youll be supporting local shapers!
