This board is a great tool for progressing your surfing in small surf. Not to mention its ability to still work really well in the chest- head high days. Starting at the top, you have a nice flip in the nose to prevent it penetrating the water on takeoff and helps out when surfing top to bottom. Moving to the middle of the board, there is a single concave starting a little below the nose and runs all the way to the fins. Within that single concave, is a double concave that runs the same length. This helps rail to rail transitions. The middle of the board is also flat, there is no bottom curve through this board; just the nose and tail flip. That helps the board plane well through flat spots and carry momentum. Moving to the tail, right at the top of the center fin, the contour transitions to a spiral V out the tail(a favorite of Kellys). The rear of the board features a swallow tail that gives the board speed down the line and release at the top of the wave; both ideal for smaller surf. All in all, the No Brainer is a board anyone can pick up and have fun on. It is recommended to be run as a quad.
