This is the only Tiger rudder blade available from Hobie Cat®. The factory upgrade carbon rudder is slightly lighter and stiffer than Hobie’s standard Tiger rudder that is no longer available. New boats come with the carbon blades and new gudgeons. New gudgeons (#50-F18056012 upper; #50-F18056014 lower) must be purchased for older boats in order to accommodate the new blades. Special order item.
