FCS Al Merrick PC Twin+1

These fins are designed specifically for fish, funboards, and twin-fin boards. They are ideal if you want to liven up a board that feels a bit sluggish or if you want to add a bit more performance-oriented pivot to a classic twin shape.

The addition of the small trailer fin provides a noticeable boost in stability and control, especially when you are pushing hard through turns. It gives you the loose, free-flowing feel of a twin fin but prevents the tail from sliding out unexpectedly.

Yes, these are designed for the FCS II system, so they are fully compatible with any board equipped with FCS II boxes. You can install and remove them without needing any tools or screws.

These feature a progressive flex, which means they are stiff enough to provide drive when you are pumping for speed, but they offer enough give to release cleanly during turns. It is a balanced feel that works well in a wide variety of wave conditions.

Because of the low-sweep profile and narrow tip, these fins excel in maintaining trim speed, making them excellent for smaller or flatter-faced waves. However, the added trailer fin gives you enough hold to handle punchier surf without feeling like you are losing traction.
