Nitro is a top elite surf-ski developed for the elite paddlers seeking maximum speed! On flat this boat is as fast as a K1 racer but its on the ocean this surf-ski excels. Surfing characteristics in downwind with an extraordinary ability to link and climb waves. The combination of how the volume is distributed, how the cockpit is positioned and the distance to the rudder gives this ski a precise steering control even when running down a breaking wave, allowing the paddler to navigate with quick response. Comes 2019 with our latest cockpit with low bump, swept back backrest, bottle holder between your leg and a very comfy seat developed from many years feedback. The cutouts on the sides are designed to give a perfectly tight paddle catch. If you ask us, this is as good as it gets!

Why two lengths? We want to be sure that we can provide you with the best surf-ski for the type of paddling you are doing. Generally, if you are a lighter person you can benefit of a shorter hull and vice versa if you are a bigger person you can benefit of the longer hull. But this also comes down to your own preferences, what characteristics you like – how you want your ski to behave in different conditions? Even such a thing as storage space is one factor when choosing your new ski. If you are 95 kg 2 m, yes, your natural option would be the longer hull and if you are 60 kg 160 cm you likely choose the shorter. But anything in between you can choose depending on what characteristics you like. Of course if you are the bigger person choosing the shorter hull it will sit slightly deeper in the water and opposite for the lighter person choosing the longer hull it will float slightly higher.

Material and construction

Note: all NK skis are made with autoclave and prepreg technique, a process often used for space industry and F1 cars, the high pressure (up to 4 x atmosphere pressure) and heat from the autoclave together with the pre impregnated fibres guarantees a very hard bond between the layers of composite creating a extra ordinary light yet strong construction not comparable with other techniques normally used for kayaks such as vacuum infusion or other hand lay up processes.
