The FCS Retro Keel PG Clear Twin Fins are purpose-built for modern fish shapes — a low-aspect keel template that delivers the fast, loose, flowing sensation that makes fish surfing so addictive, without locking the board into a single-footed drive line.

• Low Aspect Keel Template — wide base, low area design generates exceptional drive and projection down the line while maintaining a skatey, free feel through flat sections
• Lowest Area Keel in the FCS Range — less fin area than traditional keel fins means less drag and more freedom; encourages a modern, progressive approach to twin-fin and fish surfing
• Fast and Loose Feel — designed for surfers who want the speed and glide of a twin fin without the stiff, trackiness associated with heavy keel templates
• Performance Glass (PG) Construction — solid fiberglass build delivers consistent flex, predictable drive, and excellent durability for everyday use
• Clear Colorway — clean, minimal aesthetic that works with any board color or graphic
• FCS II Compatible — tool-free installation in any board with FCS II fin boxes; no keys or screws needed

Keel twins on a modern fish feel completely different from a standard twin fin set — the wide base drives you through flat sections and transfers energy to the rail for full carves, while the reduced area compared to classic keels lets you overpower the fins and redirect quickly when the opportunity arises. The Retro Keel PG is the right choice for surfers who want that classic keel sensation without sacrificing modern surfing performance.

Board Types: Optimized for fish shapes, retro fish, swallow tails, and twin fin designs. FCS II boxes required.

Care: Rinse with fresh water after use. Store in a fin bag to prevent tip damage.
