The Spade Black Jack is today's white water kayak that perfectly assists between a river runner and a creek boat. High volume and high rocker give it the dry line ability and buoyancy that a full-on creek kayak needs. A flat bottom and a pronounced rail deliver dynamic reactivity even in calmer waters.
Both ends of the boat seem slicey, but the high volume is due to the width of the kayak. That allows the paddler to turn the boat not demanding effort or involving difficulty with only a sweep, paddle precise lines in big volume, but also stay high and dry over steep drops.
