Learn to wing without the foil attached. Simply drop the Fin Adaptor into the mast track of your Seek Air 5'9 or 6'2, Seek Prime or larger Seek foilboard and secure using the screws and washers supplied with your board. We recommend using ... the DropBox Fin Adaptor set-up along with the two Seek Air side fins for maximum performance and stability when learning how to wing. The DropBox Fin Adaptor can also be used on the Seek or Seek Prime in combination with the Detachable Stick-on Fin under your front foot, to help you stay upwind. You can use your board with the DropBox Fin Adaptor only (without the side fins) for stand-up paddling.
