I'm not sure why we call this one the "Nutbuster", but it's kind of a funny name, and seems to have stuck. It's basically a short, wide, fat, flat bottom with a hint of vee out the back of the tail to accommodate the extra width in the block. The Nutbuster is your small wave, high performance alternative. It is very fast, smooth, and easy to ride. Order it a couple inches shorter than your regular board and a little wider. You'll be ripping.
