Developed by Daniel Thomson, the "Tomo Max Keel" is a twin template that combines the straight-line drive of a keel fin with the responsiveness of a twin fin. It allows for tight turns in the pocket of the wave and stable control on the face, and was finished as Thomson's ultimate twin keel shape. This fin is an innovative hybrid, with a larger surface area than a twin fin, but smaller than a keel fin. It offers a new riding experience that exquisitely blends trim, speed, control, and style.
