For more critical conditions and better shaped waves than the BMW1.  Light belly in the nose to manage chop. Single concave with low entry rocker and lots of planing area through the middle.  Double concave to a V out the tail finish the bottom contour.  Unlike the BMW1 though, the outline is curvier into the hip, allowing the board to fit into larger waves.  When you’re ready to progress past your fish to a performance shortboard this a great first step. Waist high to well overhead.
