K1 River Craft Assault has the same hull as the Attack with 30mm more height in the boat overall in order to accommodate heavier paddlers and to make it more comfortable for paddlers with wider hips.

The K1 River Craft Assault is designed specifically as a river boat, this K1 has had great success on flat-water marathons, winning the 2011 U23 World Marathon Championships.

This River Craft offers excellent maneuverability, strong sprinting, and steady cruising speed. It needs little effort to stay on a plane, which is crucial for marathon racing. The boat comfortably carries paddlers of up to 100kg on rivers.

Its round hull runs from nose to tail, and the full tail adds volume to prevent sinking. This design reduces the porpoise effect often seen in other boats and keeps speed through turns. The Assault is the ultimate river boat for advanced, heavier paddlers.
