We’ve just had this in direct from Spade Kayaks.
Olli Grau has put the following Black Jack detail together:
The Spade Kayaks Black Jack is a modern white water kayak that perfectly bridges the gap between a river runner and a creek boat. High volume and high rocker give him the dry line ability and bouancy that a full on creek boat needs. A flat bottom and a pronounced rail deliver dynamic reactivity even on mellower waters.
