Frequently Asked Questions

Fin length depends on your board width and sail size. Use our sizing calculator above, or follow the general rule: fin size ≈ (board width × 0.6) + (sail size × 3).

G10 fins offer excellent durability and value, with good flex characteristics. Carbon fins provide maximum stiffness and performance for competition sailors, with lighter weight and zero twist under load.

The main fin box types are: Tuttle (most common, deep slot), Powerbox (wider, more surface area), US Box (American standard), and Deep Tuttle (extra deep for high-performance).

Select uses prepreg moulding in metal molds — aerospace-grade technology ensuring identical flex from fin #1 to #10,000. Every fin is made in France with 400+ prototypes tested annually. You're paying for consistent precision manufacturing impossible with hand-shaping.

We offer 30-day hassle-free returns for unused fins in original packaging. If the fin doesn't suit your setup, contact us for an exchange or refund.
