Great for surfers looking for a fin that'll feel dependable in bigger waves, but still want the ability to release the tail and surf progressively in smaller waves. These fins have a high-quality machined finish, crafted from solid fiberglass.
They are considered a medium size with a neutral template, making them perfect for a wide range of surfers and conditions.
Neutral-template solid-fiberglass thruster fins have a few standout qualities that surfers love—especially if you want predictability, drive, and control without any surprises. Here’s what makes them great:
Key Advantages
1. Predictable, Balanced Feel
A neutral template means:
Not too upright
Not too raked
Not too wide at the base
Not too narrow at the tip
This gives you a very even blend of pivot, hold, and drive. The board responds in a calm, intuitive way—no twitchiness, no sluggishness.
2. Classic Fiberglass Flex (or Low Flex)
Solid fiberglass fins have:
Stiff flex through the base → strong drive, powerful bottom turns
Controlled tip flex → smoother release without feeling springy or unstable
This flex pattern is why many pros still use fiberglass: it feels connected and precise underfoot.
3. Loads of Drive
Because fiberglass is stiffer than honeycomb or plastic, you get:
Better power transfer
More projection down the line
A feeling of “push back” when you lean hard
Neutral templates deliver this drive without being overly directional or tracky.
4. Reliable Hold (But Not Too Much)
Neutral outlines keep the fin engaged in the face but still allow:
Easy pivot in the pocket
Controlled top-turn release
Consistent rail-to-rail transitions
It's a great match for everyday beachbreaks or point waves.
5. Works on a Huge Range of Boards
Solid-glass neutral thrusters pair well with:
Modern shortboards
Grovelers
Hybrids
Step-ups
They’re the safest “plug-and-play” performance fin style.
6. Long-Lasting and Repairable
Solid fiberglass fins:
Take a beating
Resist damage better than honeycomb/carbon sandwiches
Can be sanded and reshaped if dinged
Keep their flex characteristics for years
They’re basically the “old faithful” of surf fins.
7. Great for Heavier Surfers or Powerful Riders
Since they don’t flex excessively, heavier or stronger surfers get:
More stability
Better responsiveness
Less chatter in powerful surf
Who They’re Perfect For
Surfers who want trustworthy, all-round performance
People who hate fins that feel too lively or flexy
Intermediate to advanced surfers looking for drive + control
Anyone riding a standard thruster shortboard
