FCS II Channel Islands Solution Quad Rear Fin Set - Medium
The FCS II Channel Islands Solution Quad Rear Fin Set in Medium is a fast, controlled, and highly responsive rear fin set designed by Britt Merrick and developed in collaboration with Channel Islands Surfboards. Based on the popular CI Upright template, this rear set is built to pair seamlessly with the upright CI side fins and create a performance quad setup focused on speed, hold, and tight, pivot-driven turns.
Featuring a neutral-raked template and refined 80/20 foil, the Solution Quad Rears offer a balanced feel underfoot with the stability needed to hold clean lines through critical sections while still allowing for quick release and fast direction changes. This combination makes them an excellent choice for surfers who want a quad setup that feels lively and performance-minded without losing control. When paired with CI Solution side fins, they help enhance overall drive and hold while maintaining the loose, responsive release that makes a good quad setup so fun to ride.
Built in Performance Core construction, these fins are lightweight with a progressive flex pattern that supports speed, control, and versatility across a wide range of surf conditions. While they excel in punchy, hollow waves where responsiveness matters most, they also work beautifully in open-face waves and down-the-line point break surf where speed and directional control come alive.
