Concave Keel

The Concave Keel is a fish-style shortboard from Bing Surfboards, shaped by Matt Calvani. It uses an extreme concave through the tail to accelerate rocker in the last six inches, giving tighter turns and more control than a traditional fish. Designed as an everyday board rather than just a small-wave cruiser, it works from beach breaks to reefs and points, and can be ridden 4–6 inches shorter than a standard shortboard. Suited to intermediate to experienced surfers. Only offered with glass-on fins, not fin boxes.
