Sonar AF72 or AF85 Mast

30% stiffer than the AK mast yet only 13% heavier, the AF72 mast is ideal for shallower waters, and prone surf foiling. The AF85 mast performs across all disciplines and offers you more ride height to clear waves or to heel over for tighter turns. It is also more forgiving in rougher conditions.
