Shaper Zack Flores just finished a new single-fin board. Instead of taking it for a normal spin, he grabbed the three strangest fins in his quiver and let chaos decide.
“I just finished my single fin, so instead of surfing it normally, I decided to test the three weirdest single fins I own,” Flores explained before paddling out.

The Baseline: Greenough Power Blade
Flores kicked things off with the classic Greenough Power Blade — a proven performer that set the standard for everything that followed. Solid. Predictable. The control group.
The Toothed Speed Demon: 3D-Printed CAD Fin
Things got weird fast. This hyper-hydrodynamic creation features a toothed edge designed to slice through water at maximum velocity. The verdict? Blazing fast — but borderline unrideable.
“This fin was fast, but it was kind of sketchy. Like really wobbly,” Flores reported. “I did one turn where I hit the whitewater. The board flattened out on me. It was weird… really unstable and really wobbly. Kind of sketchy.”
The Winged Dark Horse: Cheyne Horan Fin
Then came what Flores called “the final boss of experimental fins” — a wild winged design that looked like it belonged on a spacecraft, not a surfboard.
“It is quite possibly the craziest fin that I’ve ever seen. I’m super excited to try it.”
The shocker? It absolutely ripped.
“I am super shocked. I did not think it was going to work very well,” Flores admitted after the session. Against all expectations, the Horan winged fin took the crown.
The Verdict
Sometimes the craziest-looking gear performs the best. The Cheyne Horan winged fin — a design that seemed destined to fail — emerged as the surprising champion of this bizarre fin showdown.
