Futures Fins F6 Honeycomb Quad Fin Set Green M

Balanced All-Around Performance from the F6 Legacy Series

The Futures Fins F6 Honeycomb Quad Fin Set belongs to the Legacy Series and sits in the Neutral template category, meaning it is engineered for a balanced, fluid feel across a wide range of wave types and surfing styles. Whether you are driving hard off the bottom or threading through the pocket, the Neutral template delivers a predictable, responsive ride that neither stiffens into a racecar nor loosens into a drifter.

Honeycomb Construction

The F6 is built with Honeycomb construction, a layered composite method that places a lightweight honeycomb core between fiberglass layers. The result is a fin that is meaningfully lighter than a solid fiberglass panel while retaining torsional stiffness where it matters. Less mass in the fin cluster translates to quicker pivot, faster acceleration out of turns, and a livelier response underfoot. The construction is the same aerospace-lineage approach the Longo brothers brought to Futures Fins when they founded the company in 1996, drawing directly on their background fabricating precision composite aerospace components.

F6 Side Fin Geometry

The front side fins use a FLAT foil on the inside face. A flat-foil side fin channels water cleanly along the inner surface, generating consistent drive and minimizing drag in the quad cluster. The geometry is:

• Area: 15.12 sq in
• Height: 4.56 in
• Base: 4.35 in
• Foil: Flat

The taller, wider-based side fins provide the quad setup with its signature down-the-line speed and channel flow that a twin cannot match.

QD2 4.0 Rear Fins

The rear fins are Futures QD2 4.0 units with an 80/20 foil. An 80/20 foil is convex on the outside face and slightly concave inside, producing lift off the back of the board, tightening your turning arc, and keeping the tail planted through critical sections. The rear fin geometry is:

• Area: 11.67 sq in
• Height: 4.05 in
• Base: 3.87 in
• Foil: 80/20

The smaller rear fin area relative to the sides keeps the tail from locking up, preserving the quad's characteristic loose-but-fast feel while the 80/20 foil adds control at speed.

Neutral Template: Who It Is For

Futures classifies this set in the Neutral (balanced/fluid) template category with a Ride Number of 4.9 on a balanced scale. A 4.9 ride number sits squarely in the middle of the spectrum, neither biased toward stiff drive nor toward loose pivotability. That makes the F6 Honeycomb Quad a strong all-conditions choice for intermediate to advanced surfers who want one set that works across beach breaks, points, and reef sessions without chasing extremes.

The set fits the Futures Fins US box system. Confirm your board's fin box system before purchasing.

The Futures Fins Legacy

Futures Fins was founded in 1996 by the Longo brothers, who built a reputation in aerospace manufacturing and hydrogen fuel cell fabrication before turning that precision engineering toward surfing. The Legacy Series carries that foundation forward, applying composite construction techniques developed for demanding applications to fins that need to perform in critical surf conditions.
