Double 670

Imagine this: an experienced paddler and a newbie, sharing a surfski and the thrill of the waves. That’s the Double 670 for you—designed so you can bring your less seasoned buddy along for the ride without sacrificing the fun. Featuring dual independent control systems, the Double 670 lets you steer from the front, back, or both, making it as versatile as it is innovative. Want to feel like you’re running a maritime driving school? This is your boat. Thanks to a shorter hull and plenty of keel action, maneuverability and responsive handling are at your fingertips, ready to dart and dash through the water. Crafted using top-notch autoclave technology and prepreg materials, this surfski boasts a featherlight 14kg / 30lbs in our middle CarbonLite build—strong, sleek, and seriously robust. Our cockpits are the result of decades of expertise, featuring seats shaped to perfection and ergonomics that boost your footwork. There’s even a spot for your beverage right under your knees, ensuring the NK drinking bottle (included as standard) is always within reach. And let’s not forget about the deBrito self-bailer, the most efficient bilge flap on the market, effortlessly operated by foot. We’ve even tweaked the paddle entry points in this second iteration, ensuring that tighter paddle insertions are a breeze, especially from the rear cockpit. Ready to team up and take on the waves? The Double 670 is your go-to!

AUTOCLAVE PREPREG TECHNOLOGY

All our crafts at NK are sculpted using prepreg carbon and autoclaved to perfection—a technique that’s as elite as it is intricate. Not many in the kayak realm have adopted this high-end method, known for its hefty price tag and complex execution.

Thanks to the uniform distribution of material in prepregs and the meticulously controlled high temperatures and pressures in the autoclave, our surfskis and kayaks boast unparalleled strength while maintaining a surprisingly light weight.

The layers in each boat are fused under intense conditions to create an exceptionally durable bond, ensuring our kayaks are not only reliable but also built to last. This cutting-edge technology is shared with industries where precision is paramount—like aerospace and Formula 1 racing. At NK, we bring this extraordinary engineering right to your boat.
