When you take these 4.5" side fins and pair them with a 6.5" center fin on a longboard,
you are creating a 2+1 performance setup.
While the 6.5" fin is physically larger than your side fins, it is considered smallish for a longboard fin. In a 2+1 performance configuration, a common center fin size is 7" to 7.5".
This combination creates a very distinct ride. Here is how you would describe its performance characteristics:
The Overall Feel: Progressive and Highly Maneuverable
This setup transforms a traditional longboard glide into a progressive, dynamic ride. It bridges the gap between traditional longboarding and modern high-performance surfing.
Loosest Performance: It will make the longboard feel significantly looser and faster rail-to-rail than a standard 2+1 setup.
Reduced Drag: Using a smaller center fin significantly reduces drag, allowing the board to accelerate and maintain speed more easily through turns.
Key Performance Attributes
1. Drive and Pivot
The board’s primary instinct will be to turn tightly.
Pivot Point: The tall 4.5" side fins create a very strong, efficient pivot point right on the tail.
The Drivey Feel: Because the side fins are relatively tall for a 2 +1 setup, they provide significant drive when engaging the rail.
2. Excellent Speed & Release (Top Turn Snap)
The low-drag configuration allows for dynamic surfing off the tail.
Speed: Less fin area in the water means less friction, so the board will generate speed quickly.
Snap: The tall side fins provide the grip needed to push through a bottom turn, while the small center fin allows the tail to release easily at the top of the wave for snappy, vertical redirections.
Best Conditions and Surfer Style
Who is it for? A performance-oriented longboarder who prioritized aggressive turning, vertical surfing, and speed over traditional "logging" or extended noseriding.
Best Waves: Peakier, faster, or beach-break conditions where you need to change direction quickly in a tight space. It is not ideal for long, slow point-break walls.
