How it surfs
Stab Magazine covered the template when it launched, framing it as an all-rounder from a shaper whose boards sit under a lot of good surfers, and rating it suitable from intermediate to expert.
The numbers back the pocket-turn brief. At Medium, base 109.2 mm against depth 116.4 mm with 31.7 degrees of sweep is a relatively upright fin, which is why it pivots rather than draws long arcs the way a raked template does.
This is the natural pairing for a Lost board, and FCS's own Mayhem fin guide maps the template across the Driver 3.0, Rad Ripper and Stub Driver models.
Volume & sizing chart
Use the chart below as a starting point. Add half a litre if you are less experienced, subtract half a litre for a looser feel.
| Size | Volume | Rider weight | Best for |
|---|---|---|---|
| Small | Base 106.3 mm | 55–70 kg | Lighter surfers |
| Medium | Base 109.2 mm | 65–80 kg | Most surfers |
| Large | Base 111.9 mm | 75–90 kg | Heavier or powerful surfers |
How it compares
| Board | Best at | Wave range | Aggregate score |
|---|---|---|---|
| FCS II Reactor | Same family, essential-series pricing | Beach break | 8.9 |
| FCS II Accelerator | More drive and hold | Reef break | 8.9 |
| FCS II Al Merrick PC AirCore | Rake and long-arc drive | All conditions | 9.4 |
Verdict
An upright, quick template with enough base to hold a hard turn. If you ride a Lost or another hybrid performance shape and want a fin that snaps in the pocket rather than drawing long arcs, this is the obvious set — and the FCS customer rating is one of the strongest in the shaper series.
