FCS II Album Twin Keel Performance Glass Twin Fins

The **FCS II Album Twin Keel Performance Glass Twin Fins** are tuned for **high-performance surfing** on modern keel twin models, combining the speed of a keel with a more responsive, performance-oriented feel. Designed to narrow the gap between a traditional keel template and a contemporary twin template, this set offers a balanced approach for surfers looking for drive, flow, and tighter directional control.

The template takes visual cues from a regular performance fin, but adds **more width through the base and middle** for drive and acceleration. At the same time, the **significantly more curved trailing edge** sets it apart from older keel designs, helping the fin release more cleanly through turns. This makes it well suited to surfers who want the smooth trim and speed of a twin setup without the overly locked-in feel that can come with larger, higher-area keels.

A **high sweep angle** delivers a moderate level of hold and sustained drive, supporting longer lines and committed rail work. The **tapered tip** and **low-profile shape** reduce tracking, improving manoeuvrability and making direction changes feel more controlled and fluid. The result is a semi-keel with enough control for powerful turns, but with the freedom needed for more radical surfing on modern twin outlines.

Positioned in the **small-medium size category**, this keel is particularly suited to lighter surfers and female surfers seeking a twin fin that feels easier to dominate through turns. It is also a strong match for surfers riding modern keel twin boards, including designs developed to work with this more progressive fin profile.

Built in **Performance Glass**, these fins are machine cut from layers of solid fiberglass. This construction produces a **stiff flex characteristic** that holds its integrity under heavy load and in demanding conditions. For surfers pushing speed and rail pressure, Performance Glass offers a stable and consistent response, especially when compared to softer flex constructions.

As part of the **Carver fin family**, this set favours **powerful, drawn-out turns with added hold**, while still maintaining the looseness expected from a refined twin fin setup. Designed to fit the **FCS II Fin System**, it can be used across a wide range of boards, including fish, funboards, and dedicated twin fin models.
