Longboard Fins
Kona longboard fins come in three templates and sizes from 7 to 10 inches. Colorways you won't find at other shops, shaped for how you actually ride.
Your Guide to Longboard Fin Types and Sizing
Your longboard fin controls how the board turns, trims, and holds a line. Knowing how each template performs helps you pick the right one for your board and your style.
Pivot vs Flex vs Classic: What Each Template Does
The Classic balances hold and release with moderate rake. Solid choice for varied conditions. The Pivot has a wider base and upright profile that anchors the tail for cross-stepping and noserides. The Flex bends under load, generating speed and a looser feel for performance longboarding.
How to Size a Longboard Fin
Longboard fin size follows a simple rule: match fin inches to board feet. A 9-foot log pairs with a 9-inch fin. Go up an inch for extra hold, down an inch for a looser ride. Heavier surfers should size up for more control.
Matching Your Fin to Wave Conditions
Small, mushy days favor the Pivot, which drives through flat sections. Steeper waves call for more rake so the tail releases into turns. Choppy surf needs a stiffer fiberglass fin that tracks straight. Clean, glassy walls suit the Flex, which bends through smooth arcs and builds speed.
Pair your fin with a longboard and a leash, or browse funboards and hybrids for a shorter setup.
Frequently Asked Questions About Longboard Fins
How does fin placement affect my longboard?
Sliding the fin forward in the box loosens the tail for easier pivots. Sliding it back adds stability through turns. Start centered and adjust a quarter inch at a time until it feels right for your conditions.
Should I ride a single fin or a 2+1 setup?
A single fin longboard gives you classic glide with smooth, drawn-out turns. Adding sidebites in a 2+1 setup increases drive in more powerful waves. Trim and noseride? Single fin. Want to push harder through turns? Try the 2+1.
Will these fins fit my longboard's fin box?
Kona longboard fins use a standard base that fits most US-style center boxes. This is the box found on the majority of longboards made in the last 40 years. Futures or FCS center boxes need an adapter or system-specific fin.
What fin is best for noseriding?
The Pivot is the go-to noseriding fin. Size it an inch taller than your standard single to maximize tail hold. Set it toward the back of the box and pair with a board that has a wide square tail and nose concave for stable noserides.
