Built to complement our Tri Plane Hull Single midlength, Devon worked on this sleek single-fin that is available in three sizes: 8”, 8.5” and 9”. The CI Single Fin template is rather upright, which helps the board pivot and turn on dime—while its slender outline and conservative rake profile provide a nice flow on down the line point breaks. Our general sizing guideline goes as follows: 8” for 6’7” & under; 8.5” for 6’8” to 7’5”; 9” 7’6 & over. The CI Single-Fin is also an ideal pairing for those looking to ride their CI Mid as a single-fin. This fin can also be used with our CI Mid sidebites for longer boards in the 9-foot-plus range.
Since 1969, Channel Islands Surfboards has led performance surf design through innovation, quality, and collaboration with the world’s top surfers. Built in Santa Barbara, CI continues to push modern surfing forward.
