Quick answer: The FCS II Harley Ingleby fins come as thruster, quad and mid tri quad sets for mid-lengths and longboards. A thruster feels stable and controlled, a quad feels faster and looser, and the tri quad lets you switch between the two feels.
If you are an intermediate surfer, or moving up from beginner, start with the thruster for control. Try the quad once you want more speed.

Who Are Harley Ingleby Fins For?
Mid-length and longboard surfers with an FCS II fin box. They fit boards like the Moe, MID 6 and HI4.
Intermediate surfers who want to feel the difference a fin set makes. Surfers moving up from beginner can start with the thruster and add a quad later.
What Is the Harley Ingleby Thruster Set?
An extra large thruster set with a 5 1/2 inch center fin, made in Performance Glass. Performance Glass is a stiff, steady fin material.
It gives stability and hold, which suits larger riders and bigger boards. The center fin can be moved in the box to change the feel.
What Is the Harley Ingleby Quad Set?
A quad set with an air core, a light core inside the fin that adds spring out of turns. It weighs less than a Performance Glass set.
Four fins and no center fin make the board feel faster and looser. It is a good choice once you are comfortable on a thruster.
What Is the Harley Ingleby Mid Tri Quad?
A set that lets one board feel like a quad or a thruster. It has two flat foiled side fins and rear fins that are a little smaller than the sides.
Flat foiled rear fins feel playful. 50/50 foiled rear fins feel more stable in bigger waves. On a five fin board you can also switch to a thruster.
How Do I Pick the Right Set?
| Set | Feel | Good start for |
|---|---|---|
| Thruster | Stable, controlled | Moving up from beginner, larger riders |
| Quad | Faster, looser | Intermediate surfers wanting speed |
| Mid tri quad | Switch between feels | Surfers who want to try both |
