From the CI Surfboards Website:
The idea came when riding the original Dumpster Diver while filming "Out of the Rafters" and tripping out how tiny and short the Dumpster Diver felt and wanting to build a longer - modernized version. - Dane Reynolds
The DD2 has a wider nose and tail, more nose and tail rocker, and a more subtle single concave. These updates, among other tweaks, allow the board to excel in a wider range of conditions and let you rip as hard as you think you do!
