About this fin
The Channel Islands Side Bite Fins add bite, drive, and extra hold to your board without sacrificing speed or flow. Designed to enhance rail engagement and control — especially in bigger or steeper surf — they’re the perfect complement to single fin or 2+1 setups. Easy to pair and highly versatile, these fins help unlock sharper turns and more confident arcs while maintaining smooth, responsive performance.
