This model is an all around performance shortboard specifically designed for radical, high performance surfing. The Diamond Back features a special diamond tail which shortens the rail line, giving the board more snap off the top. This design has single concave through the middle of the board with a deep concave through the back third. This board turns quickly, but also maintains speed. It's a great design for head high to slightly overhead waves that need to be destroyed. Fin System: Future Length: 6'0" Tail Width: 14.6" Center Width: 18.5" Nose Width: 11.3" Thickness: 2.25"
