The Cross boards are the smallest boards in Amundson's line, and designed for paddlers who want a versatile board for flat water use as well as surfing waves. Cross boards use a Constant Flow rocker, which makes them track well so you are not switching the paddle from side to side all the time, but keeps them loose enough so you can have some fun in the surf. Also incorporated is a flat bottom, which maximizes stability, and a little kick in the nose to prevent pearling while dropping into a wave. The Cross boards hit the sweet spot for maximum versatility in an all-around board. If you spend a lot of time paddling on lakes, bays, or rivers, but you still want to make sure you have the right board for a trip to the surf, grab a Cross. You will not be disappointed!
