Designer: George Greenough
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.
True Ames makes this fin in Volan only because its high-aspect ratio design requires it to be made with the strongest and thickest weave possible. Make no mistake–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.
True Ames builds its Volan fins around flex as much as outline. Made by True Ames in Santa Barbara, CA. The Volan panels are laid up and templated so the weave runs the right way, and the flex comes from the body of the fin rather than just the tip. That gives speed and projection off the bottom and through turns.

What people say
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.
From True Ames
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.
Our take
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.

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.
