Full Futures Al Merrick Twin

The Twin + 1 configuration offers the speed and loose, skatey feel of a twin fin, but the smaller center stabilizer adds just enough control and pivot to keep you from sliding out during tighter turns. It is a great middle ground if you want more drive than a twin but more freedom than a traditional thruster.

These fins use the Futures fin system, which is standard on many performance surfboards. Before purchasing, check your board's fin boxes to ensure they are labeled as Futures compatible, as they will not fit boards designed for FCS or other systems.

The honeycomb construction reduces the overall weight of the fins while maintaining a consistent flex pattern. This makes the board feel more responsive and lively under your feet compared to heavier, solid fiberglass fins.

The XL size is designed for larger surfers, typically those weighing over 190 lbs (85 kg). If you are a lighter surfer, these fins may feel too stiff and provide too much hold, which can make the board harder to turn.

These fins are highly versatile and excel in a wide range of conditions, from small, mushy days where you need extra speed to generate momentum, to clean, lined-up waves where you want to carve with confidence. The added stabilizer makes them more reliable in punchier surf than a pure twin fin setup.
