FCS II Album Twin Keel Performance Glass Twin Fins

The FCS II Album Twin Keel Performance Glass Twin Fins are designed for high-performance twin fin surfing, offering a refined balance between classic keel speed and a more responsive, modern feel. Developed for contemporary keel twin models, this set narrows the gap between a traditional keel template and a performance twin template, making it a strong option for surfers who want drive, flow, and cleaner directional control.

The template follows a semi-keel concept with visual cues taken from a regular performance fin, but with more width through the base and middle. This adds hold, drive, and acceleration, especially when building speed down the line or pushing through longer rail engagements. Compared to older, higher-area keel shapes, the overall profile is tuned to feel less restrictive underfoot.

A notably curved trailing edge helps the fin release more cleanly through turns, reducing the tracky sensation often associated with larger keel designs. Combined with a high sweep angle, the fin maintains a moderate level of hold and sustained drive, supporting drawn-out lines and committed surfing without losing the freedom expected from a modern twin setup. The low-profile shape and tapered tip further improve manoeuvrability, making transitions feel smoother and more controlled.

Positioned in the small-medium size category, this set is particularly well suited to lighter surfers and female surfers looking for a twin fin that is easier to control through turns. It also pairs well with modern keel twin boards designed around a more progressive fin profile, while remaining versatile enough for other compatible twin setups.

Construction is in Performance Glass, machine cut from layers of solid fiberglass. This delivers a stiff flex with strong integrity under load, giving the fin a stable and consistent response when speed increases or rail pressure builds. For surfers who prefer a more direct connection and reliable hold in demanding conditions, this construction supports a precise, controlled feel.

As part of the Carver fin family, the Album Twin Keel favours powerful, drawn-out turns with added hold, while preserving the looseness needed for more progressive twin fin surfing. Designed for the FCS II Fin System, it can be used across fish, funboards, and dedicated twin fin boards.
