A four-time consecutive world champion, Mark Richards reshaped the twin fin in the late '70s, pairing it with a self-shaped board that carried him to a run of dominance still unmatched in the sport's history. His designs remain foundational to modern twin-fin performance, built around speed, flow, and maneuverability in smaller, punchier surf.
