Replace your mast or get another mast height option with the Phase 5 Nova Foil Mast. Phase 5 Foils typically come with the 28″ mast so users can have the height to pump their hearts out or just fly higher than not. If you have beginners learning the sport you can opt for going to an 18″ mast height for ease while learning, then switch to the higher height once comfortable to allow for bigger pumps above the water.
