This shape's hull bottom is what makes it unique, it's got a sort of belly to the bottom that helps the board turn over rail-to-rail super easily. Hull bottoms are the opposite of concave bottoms, instead of a concave where the arch of the board reaches up into the centerline, it's a convex bottom where the centerline reaches down into the water. This creates a truly unique feeling of connection to the water that can only be achieved with a hull. The TJ Hull Rider has a hull bottom in moderation, meaning you get the feeling of connectivity in the wave face with an ease-of-use not common historically in hulls. Dan Mann designed this shape with a rounded pintail and a slightly fuller nose outline, giving you more stability while cross-stepping or trimming. It's also got a tear drove concave cutout of the hull bottom, decreasing weight in the nose increasing maneuverability, while also getting some airflow under the nose to help get lift during nose rides. And the shape's flatter entry rocker makes wave catching a breeze, with some gentle rocker in the tail for maneuverability. In this shape, it's beneficial to have the extra volume because you're not losing any performance.
