FUTURES McCallum Twin Keel Fins

These fins are designed specifically for the Futures fin system. If your board has Futures boxes, they will fit perfectly; they are not compatible with FCS or other fin box systems.

Fiberglass offers a stiffer, more responsive flex pattern than molded plastic. This provides a more traditional, solid feel that holds its shape through turns, giving you more drive and stability in varied surf conditions.

These are specifically engineered for retro twin fish shapes. While you could technically put them in other boards, their elongated profile and wide base are designed to complement the specific rocker and outline of a twin keel fish, not the performance characteristics of a modern thruster.

The wider base acts as an engine, generating significant drive and speed down the line. The elongated profile helps you maintain that speed through turns, providing a reliable, locked-in feeling that prevents the board from sliding out during aggressive maneuvers.

These fins are accessible for any surfer comfortable on a twin-fin setup. They provide a predictable, smooth ride that is forgiving enough for intermediate surfers while offering the hold and drive that advanced riders look for in a classic fish.
