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 two Detachable Stick-on Fins or the Seek Air Side Fins for maximum performance and stability when learning how to wing. You can use your board with the DropBox Fin Adaptor only (without the side fins) for stand-up paddling.Includes:Dropbox Fin Adaptor, Seek Air Fin, Dropbox Screw Pack (4x T40 M8x23mm Screws, 4 x T-Nuts)FeaturesAlways use in conjunction with two side finsInserts into CST Base DropBox mst trackProvides lateral resistance for forward drive to stay upwindSaves your mast from damage in shallow waterCompatible with any 165x90mm foil mast track
