CI Log Fin



Channel Islands CI Log Fin

The CI Log Fin is the most balanced longboard template you’ll find anywhere. Its custom drawn outline by Wayne Rich for the CI Log provides incredible drive through turns while remaining free and sensitive feeling during critical turns in the pocket. Aside from a slightly more swept back rake profile, it also has a tad bit fuller tip area when compared to other Greenough-esque templates available today—making the CI Log fin ideal for maximum lift and hold in steep, curvy sections when you’re perched high and tight. This fin is made with solid fiberglass construction and comes with a satin finish and customized sleeve to protect. Wayne shaped this fin to have a fuller leading foil for better control and power out of every turn. From tip to tail, this is the best performing longboard single-fin you can ride.

Available in Black, White and Volan. Sizing includes 9.5”, 10” and 10.25”
