The Fin
Christian Beamish's twin for Surfboards California — a hybrid of a performance twin and a keel, wide through the base and flat-foiled, for boards that need settling down.
Sold as a pair in solid fiberglass, Futures compatible, in smoke. 5.21" deep on a 6.27" base — more base than height, which is keel territory — but the rake is gentle and the profile moderate rather than full, so it never tracks the way a true keel does. Flat foil. It sits between the two classic designs on purpose and borrows from both: the drive and power of a keel, with the manoeuvrability and response of a twin still intact.
How that reads
Base is drive and hold; height is what lets a fin turn. This one is loaded toward the base, so the board grips through a bottom turn in surf with real push and keeps pushing instead of spinning out the back. The moderate profile and gentle rake leave enough response for fast bottom-to-top transitions, which is exactly what a full keel gives away. Underfoot it feels stable and strong rather than skatey.
Who it suits
Wide-tailed fish, retro fish, and any twin that gets too loose once the surf is chest high and over — point breaks and clean walls with power behind them. Heavier surfers, and thruster converts who push hard through a turn and want the fin to stay put while they do it.

What people say
Keep enough of the drive and hold of the keel while introducing the release and looseness of the upright twin.
Way more single fin than Thruster, but still with the ability to jam it in the hook of the wave.
Our take
A hybrid fin that refuses to apologize for leaning keel. Bottom turns go long and committed — the wide base delivers keel-level drive and projection while the moderate rake and height let you actually pivot out of the turn. Riders looking for snappy skate-release exits will find it claustrophobic; everyone else gets the drive without the lock-in.
More About This Fin
The Beamish Twin was designed by Carpinteria shaper Christian Beamish of Surfboards California and is produced by True Ames in solid fiberglass with a raw sanded finish. It comes in one size with a Futures-compatible base, measuring 5.21 inches tall with a 6.27-inch base, and carries 80/20 foils and 5.5 degrees of cant. It was built for Beamish's twin fin boards — round-pin channel bottoms and double-wing swallows — which cluster in the 5'7"–6'2" range.
