FLIP-STICK Bliss-Stick

Simply a wicked playboat. Short and radical, the Flip-Stick will not limit even the top paddlers. Loops become within reach of intermediate paddlers, and yet a great river boat.
Short, light and maneuverable. Heaps of rocker keeps the bow from burying and provides additional foot room and comfort.
The design brief was a freestyle boat that didn't limit the boater from executing the latest moves, specifically those than involve air, and a freeze frame video replay to comprehend.
All freestyle moves are achievable. The short length makes rotations very fast which takes a little getting used to, but puts loops within grasp of the recreational paddler.
