⚔️ Hydrus Katana 2.0 Race Fin
Razor-Edge Speed. Locked-In Precision. Real-World Performance.
⭐⭐⭐⭐⭐
“The Katana 2.0 feels alive under the board — instant response, fast acceleration, and smooth through turns. It holds a line but never feels stiff. The best all-conditions race fin I’ve used.”
— Ethan Woodthrall., SUP Racer
⚡ The Fin That Wins — Everywhere
The Katana 2.0 is our sharpest weapon in the Hydrus race lineup — purpose-built for speed, responsiveness, and agility in real-world conditions.
Most “elite” fins are tuned for glassy, controlled racecourses. The Katana was tested in what you actually paddle: wind, chop, crosscurrents, and chaos. The result is a fin that pairs lightning-fast acceleration with enough bite and stability to stay composed when conditions turn ugly.
With 229 cm² (35.5 in²) of surface area, the Katana 2.0 cuts drag to the bone while holding a rail-straight line — so you can paddle harder, turn faster, and waste zero energy correcting your course.
🏁 Why Choose the Katana 2.0
1️⃣ Engineered for Elite Speed
Everything about this fin is designed for velocity.
Its refined foil, minimal drag, and tuned stiffness keep your board gliding fast and clean whether you’re sprinting or maintaining top-end pace over distance.
-
Lower surface area = faster acceleration
-
Efficient foil = effortless glide
-
Tight tracking = less wasted motion
The Katana delivers pure forward projection — every watt of effort goes into speed.
2️⃣ Low Drag, High Tracking
This isn’t a twitchy, unstable race fin.
The Katana’s deep, balanced profile lets you go fast without fighting for control.
It tracks confidently across chop and wakes, keeping your cadence clean and efficient.
“Less correction = more speed. That’s the simple math of racing.”
— Jason Z., Hydrus Co-Founder
3️⃣ Built for Real Conditions
Unlike shallow race fins that only perform on perfect flatwater, the Katana’s 9.5” depth is intentional.
That extra depth adds noticeable stability and drive when you’re battling boat chop, crosswinds, or messy water.
-
Better control = cleaner technique
-
Cleaner technique = faster times
The Katana keeps you centered and composed so you can push harder when it counts.
4️⃣ Buoy-Turn Killer
Its narrow outline and tuned rake make it incredibly responsive in turns.
Quick accelerations out of pivots. Smooth resets into the next sprint.
Ideal for course racing, technical races, or anytime agility equals advantage.
