FCS II Modern Keel Performance Core AirCore Twin Fins
Model: FCS Specialty
Construction: Performance Core
Fin set: Twin Fin
Fin base: FCS II
Upright keel template designed for traditional fish shapes.
Overview
- Upright keel template designed for traditional fish shapes.
- Lower sweep (rake) than most conventional, wider based keels which allows it to pivot in a really tight radius.
- High area and depth not only delivers a feeling of control when pushed harder on the open face, but helps to maintain tremendous speed through roundhouse cutbacks.
Board Types
- Designed to fit the FCS II Fin System.
- Recommended for all board types including fish, funboard and twin fin boards
Performance Core + AirCore
Fins with AirCore Technology feature a pressed polyurethane foam core that mimics the geometric foil of the fin. AirCore technology reduces the amount of fiberglass required in the RTM moulding process making it much lighter while allowing total manipulation of the flex.
A quick note about our photos!
We use a mix of official brand images and real-life shots from our warehouse to help you make an informed decision.
That said, what you see might differ slightly from what you receive — simply because we can't photograph every possible variation.
For example, a photo might show a 6'2 board with Futures fin boxes, while you've selected a 5'10 with FCS II. Don’t worry — you’ll get exactly what you ordered.
Sometimes, small details like the logo, its placement or overall colour tones can vary slightly depending on the production batch, camera, lighting, or even your screen settings.
These are always only minor differences, and in most cases, the photos are spot on - but we totally get that buying online can feel tricky. If you ever want more details, just drop us a message — we're happy to help!
