Christine Brailsford Caro's high-aspect twin for Furrow Surf Craft, in solid fiberglass, FCS and Futures compatible.
The Fin
Christine Brailsford Caro's high-aspect twin for Furrow Surf Craft, in solid fiberglass, FCS and Futures compatible.
Caro shapes as Furrow Surf Craft, and this is a high-aspect twin: tall for its base, the opposite bias to a keel.
How that reads
High aspect means the fin is efficient — it holds with less area and less drag, so the board feels loose and quick to change direction rather than locked into a line. It gives up the straight-line drive a keel or a wide-based twin generates.
Who it suits
Twin-fin boards ridden actively, with a lot of direction changes, in surf with enough push that drive is not the problem to solve.

What people say
It's an honor to know that Skip likes them on his boards as much as I love them on mine.
The High Aspect Twin combines the pivot and release of an upright twin with the drive and hold characteristics of a keel.
The natural home for this fin is the Furrow lineup and the short, playful waves it was built around — Loose Control was designed for days where you want to turn a lot without washing out. And when Skip Frye keeps ordering sets from a designer every few months, it signals something real.
Christine Brailsford Caro of Furrow Surf Craft (founded 2012 in Encinitas) designed the High Aspect Twin by combining her original twin template with traditional keel geometry. The fin measures 5.05" tall with a 5.46" base, runs a flat inside foil, and is sold through True Ames in both Futures- and FCS-compatible versions. It is used across Furrow's California Fish, Floyd Pepper, Long Fish, FP Longo, and Samsara Twin models, and Skip Frye has run the fins in his Long Fish models since 2016.
