True Ames Greenough 4A Volan Single Fin pinna surf
The Greenough 4-A in Volan fiberglass — George Greenough's all-round single fin, in nine heights, for anything from a shortboard to a longboard.The 4-A is the fin True Ames has built longer than any other, and the one that works on the widest range of boards: a medium profile with a full base and a tapering, moderately flexible tip.
La pinna
La Greenough 4-A in fibra di vetro volan — il single fin tuttofare di George Greenough, in nove altezze, per qualsiasi tavola, dallo shortboard al longboard.
La 4-A è la pinna che True Ames produce da più tempo di ogni altra, ed è quella che funziona sulla gamma di tavole più ampia: profilo medio con base piena e punta affusolata, moderatamente flessibile. In Volan il flex nasce dal corpo della pinna più che dalla sola punta, perché i pannelli sono laminati e sagomati in modo che la trama corra nel verso giusto. Si traduce in velocità e proiezione in uscita dal bottom e nelle curve. Nove altezze, da 6.5" a 10.5", tutte in Volan.
Come si sente
Prima di tutto la base piena: è da lì che arriva il drive in uscita dal bottom, ed è il motivo per cui la 4-A non dà mai la sensazione di aver esaurito la spinta a metà curva. La punta è dove cede — si carica e ritorna, così la pinna tiene quando glielo chiedi e rilascia quando il rail si stacca. Neutra più che specializzata: non la tenuta più profonda in noseride, non la più sciolta in pocket, e sempre stabile in tutto quello che sta in mezzo.
A chi è adatta
Più o meno qualsiasi tavola con un box singolo — shortboard, mid-length e longboard la accettano tutte — con l'altezza come modo per regolarla. Più alta per la tenuta su una tavola più grande, più bassa per una coda più sciolta. Il Volan è la vetroresina più flessibile, quindi questa è la 4-A per chi vuole che la pinna fletta e ritorni invece di restare rigida sotto i piedi.

Cosa ne dicono
Riders describe it as more powerful coming out of turns than a standard glass 4A.
The Volan layup springs from the trunk, not only the tip -- the full base still gives push off the bottom, but the whole fin feels alive under load.
The do-everything single fin for an egg or speed-shape mid-length: it trims fast, holds an arc, and unloads with snap on the way out, usually in the 7.5" to 8.5" band. It trades a little composure for spring and slip, so if your goal is planted noseriding on a heavy log, a pivot fin like the Heritage is the better tool.
The Greenough 4A Volan is the George Greenough 4A template laid up in Volan, a thicker weave that flexes through the body of the fin rather than only the tip; True Ames orients the panel weave so the fin springs from the trunk. The template has a full base, moderate rake, and a tapering tip. It is offered in sizes from 6.5" to 10.5" and runs on eggs, mid-lengths, and a wide range of single-fin boards.

Perché il Volan
Volan is a woven fiberglass cloth — heavier, coarser, and more flexible than the solid fiberglass used in the standard 4A. It's laid by hand over the fin blank and finished with a resin that cures to a warm amber tint. No two volan fins look exactly the same.
The difference isn't cosmetic. Solid fiberglass flexes mostly at the tip — the body stays rigid, so energy transfers immediately. Volan flexes through the entire fin. It loads energy into turns and releases it progressively, giving a smoother, more connected feel. Surfers describe it as "warmer" — the fin does more of the work, trimming and holding without demanding constant input.
The extra weight is part of the design. A volan 4A is roughly 15–20% heavier than its solid fiberglass counterpart, and that mass adds momentum. Through flat sections and lulls, the fin carries speed instead of stalling. On a longboard trimming down the line, that momentum is the difference between making the section and bogging.
When to choose Volan
Volan's momentum and smooth flex match the trim-and-glide style of classic shapes. The fin carries you through sections instead of demanding constant pumping.
If you like a fin that loads into turns and releases gradually — more flow, less snap — volan rewards a patient, drawn-out style.
Down-the-line waves let volan's progressive flex and carry shine. You'll notice the difference most on long, open faces where trimming speed matters.
The amber tint, raw cloth texture, and hand-finished irregularity are part of the appeal. Volan fins look like they belong on a traditional board.
When to stick with solid fiberglass
If you're pumping, snapping, and surfing aggressively, solid fiberglass gives more immediate response and a stiffer drive through turns.
Short, steep waves reward the instant energy transfer of solid glass. Volan's progressive flex can feel sluggish when the wave demands quick changes.
Solid fiberglass is lighter. For boards where swing weight matters — shorter single fins, 2+1 setups on mid-lengths — solid glass keeps the tail light.
Volan vs Solid Fiberglass at a Glance
| Volan (this fin) | Fibra di vetro piena | |
|---|---|---|
| Flex Pattern | Full-body, progressive | Tip-focused, immediate |
| Weight | Heavier (~15–20% more) | Lighter |
| Feel | Warm, smooth, forgiving | Direct, precise, snappy |
| Speed Through Flat | Carries momentum | Needs pumping |
| Turn Response | Gradual load and release | Instant engagement |
| Finish | Raw amber tint, hand-laid texture | Matte, uniform |
| Best Waves | Point breaks, mellow walls, long lines | Beach breaks, punchy hollow waves |
| Best Boards | Traditional logs, gliders, hulls | HP longboards, mid-lengths, 2+1 setups |
Both versions use the same 4A template — same outline, same rake, same foil. The difference is entirely in how the fin flexes and how that flex translates to feel underfoot.
