Dennis Parton has over 25 years of experience, designing world title winning fins for many of the top professional windsurfers on the PWA World Tour.

This heritage has led him to the development of the finest G-10 fin production facility on the planet. Our machines and software are state of the art and Tectonics only uses the finest, hand selected panels of G-10 available on the market.

Every single fin is hand-finished to exacting specifications and no fin is delivered without Dennis's personal inspection and approval.
