Surf Fins

Surfboard fins may be small, but they decide everything. They are the violin strings of your board — subtle, sensitive, and capable of changing the entire melody of your ride. You could write an entire book about fins, and many surfers practically have, debating templates, flex, rake, foil, and materials like musicians obsessing over tone. Because when it comes down to it, fins shape how your board performs, holds, releases, and ultimately sings on a wave.

Thruster, quad, single, or 3+2 — each setup tells a different story. A thruster delivers balanced control and predictability. A quad generates speed and drive, gripping through fast, hollow sections. A single fin flows with classic style and smooth lines. A 3+2 setup blends stability with versatility, especially in midlengths and longboards. The right fin configuration can completely transform how your board feels under your feet.

We offer fins compatible with Futures, FCS, and FCS2 fin systems, giving you the flexibility to dial in your setup precisely. Different sizes, stiffness levels, materials, and templates allow you to match your fins to your weight, board design, and wave conditions. A subtle change below the waterline can unlock sharper turns, quicker acceleration, or more hold when it matters most.

Choosing fins is part science, part intuition. Your weight, board volume, wave type, and personal style all play a role. Swap your fins, and the board responds differently — tighter, looser, faster, smoother. It’s a tuning process that never really ends, and that’s part of the beauty of surfing.

At Boardside.lv — your surf shop in Riga, Latvia — we bring real Baltic Sea surfing experience into every recommendation. Baltic waves have their own character: wind-driven, shifting, sometimes short and punchy. We know how equipment needs to perform in these conditions. Whether you’re dialing in your everyday Baltic setup or preparing for an ocean trip abroad, we’ll help you choose fins that make your board feel alive where you ride most.
