{"product_id":"fcs-ii-album-twin-keel-performance-glass-twin-fins","title":"FCS II Album Twin Keel Performance Glass Twin Fins","description":"\u003cp\u003eThe **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.\u003c\/p\u003e\u003cp\u003eThe 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.\u003c\/p\u003e\u003cp\u003eA **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.\u003c\/p\u003e\u003cp\u003ePositioned 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.\u003c\/p\u003e\u003cp\u003eBuilt 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.\u003c\/p\u003e\u003cp\u003eAs 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.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemplate\u003c\/strong\u003e, Album Twin Keel, Semi-Keel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSurfing style\u003c\/strong\u003e, high-performance twin fin surfing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFeel\u003c\/strong\u003e, speed, smooth turns, radical directional changes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e, high sweep, low profile, tapered tip\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrive characteristics\u003c\/strong\u003e, added width through base and middle for hold and acceleration\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelease\u003c\/strong\u003e, curved trailing edge for a less tracky feel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize category\u003c\/strong\u003e, small-medium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFin family\u003c\/strong\u003e, Carver, powerful drawn-out turns with added hold\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction\u003c\/strong\u003e, Performance Glass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial note\u003c\/strong\u003e, machine cut from layers of solid fiberglass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlex\u003c\/strong\u003e, stiff, maintains flex integrity under force\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatibility\u003c\/strong\u003e, designed for the FCS II Fin System\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecommended board types\u003c\/strong\u003e, fish, funboard, twin fin boards\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"FCS","offers":[{"title":"Small - Medium","offer_id":57535442420094,"sku":"FALK-PG01-SM-SS-R","price":140.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0914\/5322\/7390\/files\/fcs-2-album-keel-performance-glass-twin-fin.png?v=1781448895","url":"https:\/\/www.behindthepines.eu\/products\/fcs-ii-album-twin-keel-performance-glass-twin-fins","provider":"Behind The Pines","version":"1.0","type":"link"}
