Walden Magic Model - Tuflite The Magic rocker, Magic rails, and the Magic hull are unique to Walden Surfboards, the front 1/2 of the hull is concave, this single concave transitions into a double concave in the rear, and the back 1/3 transitions into a moderate “V”. The concave nose adds lift and stability, perfect for noseriding. The double-concaved hull and hard rails make the board fast, stable, responsive, and maneuverable in all conditions. The Magic rails are hard, they tend to be harder than most other longboards, the unique bottom curves & bevels keep the rails from catching, unlike most other hard rail boards.
