Nitro 640 | Nitro 600

Nitro 640 - Carbon X with green nose

The Nitro is a top elite surfski designed for elite paddlers looking for maximum speed! In flat water this boat is as fast as a K1 (for many even faster), but on the sea and large lakes this surfski is unbeatable. Great surfing properties in the downwind with an exceptional ability to connect and climb waves.

The combination of the volume distribution, the positioning of the cockpit and the distance to the control fin results in a very agile ski that can be mastered well even in breaking waves.

Since 2020 the Nitro has been manufactured with our latest cockpit with a lot of freedom of movement, great support and feedback, bottle holder between the legs and a very comfortable seat that has been developed with many years of experience.

The Nitro 640 has the long cockpit and fits paddlers from 165cm to approx. 200cm and more. Compared to the Nitro 640, the Nitro 600 has a 5cm shorter cockpit and fits paddlers from approx. 155cm – 195cm. The cutouts on the sides are designed in such a way that a perfectly tight paddle insert is created.

If you ask us: it couldn’t be better.

Construction and design

Autoclave Prepreg Technology – All boats and paddles at NK are made with prepreg carbon in an autoclave. This is one of the most expensive and complex production processes and is not yet widespread in the kayak world. Due to the homogeneous material distribution of prepregs and the high, precisely defined temperatures and pressures in the autoclave, the boats and paddles achieve extreme strength with low weight. The individual layers form a very intensive connection, which ensures a very long service life and high reliability of the boats. The technology is otherwise used in space travel or Formula 1.
