The Sumo longboard is more of a traditional longboard in the sense that it draws classical rocker curves combined with a classical outline. The bottom consists of a single concave under the nose and rolled vee out to the tail. They come standard as a single fin and are great nose riders. Just like a Sumo you do not want to get in the way of this board. With 50/50 rails it carries steady momentum down the line with a balanced solid feel. This board is recommended for all levels of surfing.
