Fiberglass vs Honeycomb Fins — Real Performance Differences
Which Surfboard Fin Construction Actually Performs Better?
When choosing surfboard fins, one of the biggest decisions is fiberglass vs honeycomb construction.
Honeycomb fins are marketed as lightweight and responsive, while fiberglass fins are known for drive and reliability — but what does this actually mean in the water?
This guide explains the real performance differences between fiberglass and honeycomb fins, so you can choose the setup that matches your surfing.
Quick Answer
Fiberglass fins provide:
Stronger drive
Better hold
More predictable flex
Longer lifespan
Honeycomb fins provide:
Lighter weight
Faster initial response
Easier turning feel
Reduced stiffness
For most surfers — especially in real surf conditions — fiberglass fins deliver more reliable performance.
What Are Fiberglass Fins?
Fiberglass fins are built from layers of woven glass cloth saturated in resin, creating a strong and consistent structure.
This construction produces:
Controlled flex patterns
High strength
Clean energy transfer
Reliable projection
Fiberglass fins have been the performance standard for decades because they maintain consistent behaviour under load.
Typical Fiberglass Performance Feel
Solid through turns
Predictable at speed
Strong projection
Reliable hold in powerful surf
Representative Eveley fiberglass fins include:
4.75" Medium Rake Performance Thrusters – Everyday balanced performance
5.4" Big Boy Thruster Fins – Maximum hold and control
5.2" / 4.35" Big Boy Quads – Powerful wave speed and grip

What Are Honeycomb Fins?
Honeycomb fins use a lightweight hexagonal core material sandwiched between fiberglass or composite skins.
This reduces weight and increases responsiveness.
Honeycomb fins typically feel:
Quick to turn
Light underfoot
Easy to release
Slightly less planted
They are often preferred by surfers who want a lively feel in smaller waves.
Real Performance Differences
Drive
Fiberglass:
Stronger drive through turns because energy transfers more directly into forward speed.
Honeycomb:
Less drive under heavy load because the structure absorbs more energy.
Winner: Fiberglass
Hold
Fiberglass:
Better rail hold, especially at higher speeds and in powerful waves.
Honeycomb:
Can feel slightly loose when pushed hard.
Winner: Fiberglass
Flex Feel
Fiberglass:
Predictable flex that increases gradually with pressure.
Honeycomb:
More springy and immediate flex response.
Winner: Depends on preference
Speed Generation
Fiberglass:
Better speed through projection.
Honeycomb:
Faster initial acceleration.
Winner: Tie
Stability at Speed
Fiberglass:
Feels planted and controlled.
Honeycomb:
Can feel nervous at higher speeds.
Winner: Fiberglass
Fiberglass vs Honeycomb Fin Performance
Drive
Fiberglass: High drive with strong projection through turns
Honeycomb: Moderate drive with a lighter, more relaxed feel
Fiberglass fins push the board forward more efficiently, especially when you lean into a turn.
Hold
Fiberglass: High hold and strong grip on the wave face
Honeycomb: Moderate hold with a slightly looser feel
Fiberglass feels more secure when the waves are fast or powerful.
Stability
Fiberglass: Very stable at speed
Honeycomb: Moderately stable but can feel lighter underfoot
Fiberglass fins feel planted and controlled when the board is moving fast.
Weight
Fiberglass: Medium weight
Honeycomb: Lightweight
Honeycomb fins are noticeably lighter, which can make boards feel more lively.
Flex Feel
Fiberglass: Smooth and predictable flex
Honeycomb: Springy and quick to respond
Fiberglass flex builds gradually, while honeycomb fins tend to feel more reactive.
Powerful Waves
Fiberglass: Excellent control and hold
Honeycomb: Moderate performance in heavy surf
Fiberglass fins handle speed and pressure better when the waves have power.
Small Waves
Fiberglass: Very good all-round performance
Honeycomb: Excellent for easy turning and looseness
Honeycomb fins often feel more playful in weaker surf.
When Fiberglass Is the Better Choice
Fiberglass fins excel if you want:
Maximum projection
Reliable hold
Powerful wave control
Predictable performance
Long lifespan
Fiberglass is especially beneficial for:
Overhead waves
Fast beach breaks
Reef breaks
Heavier surfers
Performance boards

When Honeycomb Makes Sense
Honeycomb fins make sense if you want:
Very light feel
Easy turning
Small-wave looseness
Fast response
They are most suited to:
Small waves
Fish boards
Grovel boards
Lighter surfers
Why Many Experienced Surfers Choose Fiberglass
Once surfers begin pushing harder turns, the advantages of fiberglass become clear:
More projection
More hold
Better consistency
That’s why most high-performance and step-up fins are still fiberglass.
Eveley Pro Glass fins are designed specifically around controlled flex and reliable projection.

Common Myths
"Honeycomb fins are faster"
Not necessarily.
They accelerate quickly, but fiberglass often generates more real speed through projection.
"Fiberglass fins are stiff"
Quality fiberglass fins are designed with controlled flex patterns, not rigidity.
"Lightweight fins are always better"
Very light fins can reduce control in powerful surf.
Balance matters more than weight.
Which Should You Choose?
Choose Fiberglass Fins if you want:
Clean projection
Reliable hold
Confidence at speed
Performance consistency
Choose Honeycomb Fins if you want:
Lightweight feel
Easy turning
Small-wave looseness
