What people say
Hand-finished and designed in conjunction with the CI team, with balanced flex and a clean foil delivering dependable drive and effortless release -- best in waves with some down-the-line power.
The thruster set for a heavier or more powerful surfer who loads the fin in waves with real push -- the solid glass stiffens under hard drive and holds where lighter sets wash out. Lighter surfers or smaller, weaker waves call for the CI Tri Small or the softer Hexcore build instead.
More About This Fin
The CI Tri Large is a three-fin thruster set designed with the Channel Islands team and foiled by True Ames, here in solid fiberglass with FCS-compatible tabs. The template carries a CI-inspired foil with moderate rake, descending from the thruster sets Chuck Ames foiled for Channel Islands through the high-performance shortboard era. The same large template is also offered in Hexcore construction, and the set comes in a small size. It is sized for heavier surfers on shortboards.
