Britt reimagined that retro outline, refining the rocker and overall design to unlock greater speed, drive, and carving control while preserving the effortless glide twin fins are known for.\u003c\/p\u003e\n\u003cp\u003eThe result is a fast, loose, and incredibly fun board that excels across a wide range of conditions—from soft, weak beach breaks to clean, lined-up point waves like Rincon. Its updated rocker profile generates natural acceleration, while the twin fin setup delivers that signature skatey feel with surprising hold through turns.\u003c\/p\u003e\n\u003cp\u003eUnlike traditional high-volume retro twins, the CI Twin Fin features refined, tapered rails that feel thinner and more performance-driven underfoot. This added sensitivity translates into better control, quicker transitions, and a more responsive ride without sacrificing paddle power or wave-catching ability.\u003c\/p\u003e\n\u003cp\u003eKey Features:\u003c\/p\u003e\n\u003cp\u003eRetro twin fin outline with modern performance updates\u003c\/p\u003e\n\u003cp\u003eEnhanced rocker for speed, drive, and smooth rail-to-rail surfing\u003c\/p\u003e\n\u003cp\u003eTapered rails for improved responsiveness and control\u003c\/p\u003e\n\u003cp\u003eExcellent wave catcher in a variety of conditions\u003c\/p\u003e\n\u003cp\u003eFast, loose feel with clean carving ability\u003c\/p\u003e\n\u003cp\u003eWhether you're chasing nostalgic lines or looking to add a versatile, high-speed twin to your quiver, the CI Twin Fin delivers a perfect balance of heritage style and progressive performance.\u003c\/p\u003e\n\u003cp\u003e5'7\" x 19 3\/4 x 2 1\/2 30.7L - Futures Fins not include FCS Micro Trailer Fin included\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"Channel Island Surfboards","offers":[{"title":"5'7\"","offer_id":42092582502446,"sku":"CON-KITCH-5'7 CI","price":289.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0770\/3687\/files\/7349CE8C-B7DD-461A-B14A-8810B6F12630.jpg?v=1772734141","url":"https:\/\/www.seasidesurfshop.com\/products\/used-channel-islands-surfboards-57-twin-surfboard","provider":"Seaside Surf Shop ","version":"1.0","type":"link"}
