FCS 2 BM PG Twin Fin Set

Drive, Hold, Pivot, Release in One Twin Template

The FCS II BM PG Twin Fin Set sits squarely in the middle of the CI family, bridging the gap between the CI Keel and the AM Twin. The result is a high-area twin fin that delivers the drive and hold surfers expect from a keel fin while preserving the pivot and release that makes an upright twin template so versatile.

Designed with the CI Twin Pin and CI Mid in mind, the BM template is purpose-built to anchor the tail to the wave face, giving surfers the confidence to take a more aggressive approach on a twin fin setup. Whether you are committing to a long, arcing bottom turn or snapping off the top, these fins hold their line when you need them to and release cleanly when you ask.

BM Template Geometry

The BM template features a swept-back long leading edge that flows into a full rounded tip, a profile that places it apart from conventional twin templates. The low sweep (rake) combined with the narrow tip is what gives these fins their dual personality: they pivot and release exceptionally well, yet carry genuine trim speed and the ability to snap into a turn without the skittish feeling of a more upright design.

At the highest area of any twin set in the FCS range, the BM template produces more surface contact with the water, translating directly to more drive down the line and more security when committed to a power turn.

Performance Glass (PG) Construction

Performance Glass (PG) is FCS's entry into their fibreglass-based fin construction. The layered fibreglass build produces a fin that is lively and responsive across a broad range of conditions. PG fins flex in a predictable, progressive manner, making them a reliable choice for surfers who want real feedback from the water without the stiffness of a carbon construction. The construction also makes the BM PG one of the more accessible twin sets in the FCS II lineup at its performance level.

FCS II Fin System Compatibility

These fins are designed to fit the FCS II Fin System, the tool-free plug-and-ride system that locks fins securely without screws or keys. The tab base visible at the fin root drops directly into any FCS II box, making swaps on the beach a matter of seconds. Compatible board types include fish, funboard, and twin fin boards.

Collaboration Pedigree

The BM series was developed in collaboration with world-leading surf athletes and surfboard shapers, including its namesake Britt Merrick, co-founder of Channel Islands Surfboards. The template reflects the way Channel Islands shapes approach twin fin surfing: with a bias toward power surfing and committed rail turns, not just loose skating through sections. FCS fins are the choice of the world's best surfers and shapers, and this template carries that lineage directly.

Best Conditions and Board Pairings

The BM PG Twin Fin Set is recommended for fish, funboard, and twin fin board shapes. It performs at its best in waves with enough face to draw out a turn, where its drive and hold advantage over a narrower twin becomes most apparent. Surfers looking to push harder off the bottom on a twin fin setup will find the BM template rewards that approach more than most twin options on the market.
