Learn to wing without the foil. This durable, lightweight and removable fin with self-adhesive base is designed for use on any larger Seek or Seek Prime Foilboard to provide lateral resistance, forward drive and maximum stability. Using a fin instead of a foil enables wing-handling practice in safe shallow water environments, where you can easily walk back to shore. We recommend using the Stick On Fin in combination with a single rear fin or the North DropBox Fin Adaptor*, which slots into your foil mast track.  Place one Fin on each rail side (recommended) or a single-centre Fin under your front foot. A strong, water-resistant self-adhesive secures fin base to board, and the fin detaches from the base for easy storage – no tools required.
