Captain Fin Co. Chemistry Twin

These fins use a Futures (single tab) fin system. Please check your surfboard's fin boxes to ensure they are compatible with the Futures standard before purchasing.

The flat foil design provides a very consistent, predictable feel. It offers a balance between speed and control, making it a reliable choice for surfers who want a classic twin-fin sensation without feeling too loose.

Yes, the Chemistry Twin is designed for versatility. While twin fins are often associated with smaller, fun surf, the wide base and smooth rake on this set provide enough drive and control to handle a wide range of wave conditions, including larger days.

These fins feature a medium flex pattern. This provides a nice balance, offering enough stiffness for drive and speed, but with enough give to allow for smooth, fluid turns.

Moving from a thruster to this twin-fin setup will generally make your board feel faster and looser. You lose the center fin's stability, but gain more speed down the line and a more playful, skatey feel during turns.
