SUP fins / fin boxes

SUP fins and fin boxes from Starboard, Aztron and Aquatone: centre fins and side fins, US box and FCS II fins, fin screws, keys and spare fin boxes.

How to choose: first check the fin box on your board (US box, FCS II or glued), then the fin size: a larger centre fin tracks straighter for touring, a smaller one turns easier for waves and rivers.
