                        🌊 Hydrus Riptide Race Fin
Smart Speed. Real-World Control. Unstoppable Glide.
⭐⭐⭐⭐⭐
“The Riptide made my board feel locked in — zero wobble, even in sidewinds and current. It slices through weeds like they’re not even there. It’s faster, smoother, and just makes paddling feel easier.”
— Darren S., Touring Racer
⚡ Race-Ready. Real-World Proven.
Meet the Hydrus Riptide — our premier SUP race and touring fin built for paddlers who chase both speed and control.
Engineered from 30T pre-preg carbon fiber, the Riptide blends race-level efficiency with everyday versatility. Whether you’re cutting through kelp forests, battling crosswinds, or charging flatwater sprints, this fin keeps your board driving straight and clean.
It’s not just a “race fin.” It’s the one fin you can trust anywhere.
🏁 Why the Riptide Fin Stands Apart
1️⃣ Weed-Shedding, Chop-Cutting Design
The Riptide’s swept-back rake profile slices through weeds, kelp, and debris — no snags, no stalls.
You’ll glide clean through sections that stop other paddlers cold.
- 
Smoothly deflects grass and pads 
- 
Reduces drag and noise 
- 
Keeps your line straight, even through “floating salad bars” 
This is speed that doesn’t quit when nature gets messy.
2️⃣ Race Foil = Smarter Hydrodynamics
Every curve, edge, and taper on the Riptide was CAD-optimized for low resistance and maximum directional hold.
The result? You paddle straighter, faster, and with less correction.
Perfect for:
✔️ Long-distance touring
✔️ Racing in crosswinds
✔️ Rivers or coastal swell
“It’s not just fast in glassy conditions — it’s faster when it’s ugly. That’s real-world speed.”
— Jason Z., Hydrus Co-Founder
3️⃣ Bigger Blade, Better Drive
At 9.25 inches tall and with ~20% more surface area than our Katana fin, the Riptide anchors your direction and boosts projection with every stroke.
It’s ideal for:
- 
Heavier paddlers 
- 
Wider or longer boards 
- 
Loaded touring setups (coolers, gear, pets) 
You’ll track straighter, make fewer corrective strokes, and maintain momentum through wind, wake, and chop.

🔬 Performance in Action

When weeds or kelp try to slow you down, the Riptide just slides past.
It’s the fin that makes your board feel calmer, faster, and more connected to the water.
💬 Customer Feedback
“The Riptide gave my touring board race-level tracking without losing maneuverability. I’m seeing 5–10% speed gains on my GPS over distance paddles.”
— Chris M., Fitness Paddler

🧭 Built by Hydrus
We don’t sell mass-produced accessories — every fin we release is designed, tested, and refined by paddlers who race, tour, and surf year-round.
Our goal: build fins that perform in the real world, not just in glassy test ponds.
“Speed isn’t just about flatwater drag. It’s about how the fin behaves when things get unpredictable.”
🏁 Bottom Line
The Hydrus Riptide Race Fin isn’t just fast — it’s smart fast.
It anticipates chop, sheds weeds, holds your course, and lets you focus on your rhythm — not your rudder.
If you paddle in real conditions, this is the upgrade that makes your board faster, calmer, and more efficient.

Hydrus: A Journey from Passion to Innovation
Founded in 2013 by two brothers and a close-knit group of friends, Hydrus was more than a business venture – it was a vision and a passion. A vision to craft limited editions of top-quality boards, infuse innovative ideas, pursue responsible manufacturing, and elevate customer experience to the heart of everything we do.
Located just outside Boise, Idaho, amidst the tranquil beauty of lakes and rivers, Hydrus has come to stand for personalized service, remarkable durability, inventive spirit, elegant minimalism, and the highest quality in the market.
Here's what our proud owners have to say:

- "Exceptional quality! I now own three boards and couldn't fathom opting for any other brand! Hydrus is extraordinary!!!" – Greg H., owner of two Hydrus iSUPs and an Armalight Board.
- "River surfing is demanding, and this board's resilience is second to none..." – Derek D., owner of a Revo SUP and ToughBlade Paddle.
Our approach to sales is as unique as our products. Instead of traditional methods, we embrace a Community Direct approach, investing in what strengthens our sport and community. For us, word-of-mouth and the self-evident quality of our products speak louder than advertisements. What we save on marketing, we give back through unparalleled customer service and continuous innovation.
In recent years, we've introduced cutting-edge technologies such as Armalight Construction, CrossBoards, composite reinforced iSUPs, Tough Blade Paddles, and boards robust enough to come with a Limited Lifetime Warranty.
Hydrus's mission is distinctive. We're wholeheartedly committed to promoting the sports we love and building our community. Although our boards may be among the most expensive to produce globally, we find ways to remain competitively priced. Our approach is transparent and honest, steering clear of exaggerated marketing, gimmicks, and irresponsible manufacturing.
