The Fin
The Greenough High Speed excels as its name implies –at high speeds . It is perhaps one of the truest examples of George Greenough’s revolutionary high-aspect ratio fin designs; similar to the wings of an airplane, its slender design will harness heaps of power and produce lift while maintaining very low drag. Longer, point break style waves make a prime venue to realize this fin’s full potential. Greenough is the man behind a continual evolution of wave-riding innovations that are widely attributed for paving the way from traditional longboarding to high-performance surfing in the pocket. He originally designed the High Speed to accompany his “Edge” boards, which have been described by renowned shaper Marc Andreini as “ two surfboards in one: a narrow concave tow board with hard edges, nose to tail, is shaped underneath a displacement hull with full lifted rails.” Like Greenough’s Edge boards, his High Speed fin works in all conditions, and prevails well in powerful surf. No matter Greenough’s original intentions for this fin, it has evolved and been proven by many to work wonderfully in a wide variety of board types–from mid-lengths to gliders, and everything in between. We make this fin in Volan only because its high-aspect ratio design requires it to be made with the strongest and thickest weave possible. Don’t get us wrong–with relatively little surface area, the fin is going to flex. But the structural integrity of the Volan will generate power and drive, and ultimately allow for optimal performance. Our Volan fins are fine-tuned with precision foils as well as proper flex. Crafted with a labor of love at our factory in Santa Barbara, CA, these fins undergo the strictest quality control. Our Volan panels are meticulously hand-laid and templated ensuring optimal weave orientation and superior strength, with flex coming more from the body rather than just the tip. This enhances speed and projection off the bottom and through turns, making our Volan fins a pinnacle of the highest performance flex characteristics. High-aspect ratio, slender design will produce power and lift with minimal drag Pairs well with many types of boards, from mid-lengths to gliders and everything in between Volan fiberglass construction generates high-performance flex

Why Volan?
Volan is a woven fiberglass cloth laid by hand and finished with a resin that cures to a warm amber tint. It flexes differently than solid fiberglass — more spring, more life, more feel through turns. Where solid glass is stiff and direct, volan breathes with the wave.
The hand-laid process means each fin has subtle texture and character. It's heavier, which adds momentum through flat sections. Surfers who ride volan describe it as "warmer" — the fin does more of the work, trimming and holding without demanding constant input.

What people say
The panels are laid so the flex comes from the body and trunk rather than only the tip, which enhances speed and projection off the bottom and through turns. It springs and accelerates rather than plants and holds.
Fast down the line, though the board overpowered the fin in a Larmo glider. Drop it in a board not built for it and it can feel floppy with little hold.
A specialist, not an all-rounder: put it on a speed-oriented single fin board or glider for long, clean point waves, where the lift and low drag pay off. If you want one fin that behaves on any board you own, the Greenough 4A is the safer pick.
More About This Fin
A slender, high-aspect single fin from the George Greenough line, made by True Ames exclusively in Volan glass because the thin profile requires the strongest, thickest weave; the panels are laid so flex comes from the body and trunk rather than only the tip. It comes in five sizes: 8.2, 8.5, 8.9, 9.25 and 9.7 inches. It is intended for purpose-built speed boards, gliders and tuned mid-lengths on long, drawn-out waves.
