The step-railed, concave-decked Precious came about when a friend asked me for a one board quiver that he could take around the world and have a good surf on. "One board to rule them all" was the call and thus the name Precious came about (Lord of the Rings nerds will get this, everyone else just don't worry about it).In order to do that, and still keep a fair bit of volume in the board, we decided to make it a step-deck. This allowed us to keep some foam in the overall board, but let it have a sensitive, high performance rail at the same time. When creating the step-deck it also makes the deck concave, which adds stability and more sensitivity to the design, and it seems to give you a little extra boost of paddle power as a side benefit.
