The Disc works best in knee to head high waves, but can really be surfed in anything from 1 foot to slightly overhead. Drive off the back foot or trim from the middle of the board, select your fin setup and have a blast. The Disc is a board designed to be fast and "skatey" all over the wave. The round nose and tail, single concave to Vee, and lower rocker make this board really fast, drivey and a great paddler. Works as a single fin, thruster, quad, 2+1 or bonzer.
