Lance SmithSean Mattison with Kelly Slater, doing research on the Nub.
Martin Potter and Peter Mel called it the guitar pick. Some folks called it the fifth fin. But Sean Mattison, creator of the cute, little, red skeg that Kelly Slater used in his quad at the Quiksilver Pro New York, calls it the "Nubster."
So Slater went to the finals in New York and Mattison, a surfer/designer/coach from Oceanside, sold hundreds of "Nubsters" on his Von Sol Surfboards website overnight.
