Small wave high performance board for small wave South Carolina.
This is what Robert has to say:
The Black Dump Truck is a Black Diamond with a squash tail. This design was made to compliment and be a stepped-up version of the White Diamond or White Dump Truck. We added three inches, narrowed it a half an inch and added a touch of rocker to the nose and tail. By making these changes, we have given this board the ability to handle much bigger surf than the White Diamond.
Here is a little video on a Black Diamond. Its the same board just with a diamond tail instead of a squash.
