A new spin on a Classic, I have refined the fish outline for a more shortboard feel while retaining the old school wave catching and speed benefits, a flattish rocker and vee right through to the front foot, deep double concaves add lift for more speed and let the wider board get on rail easier, slightly lower rails for a more sensitive feel, still lots of volume where its needed, read my reviews for the positive feedback on the Mod-retro .Can be surfed as a twin or quad fin.
