Captain Fin - Christenson Tracker 9.0 Smoke Singlefin   Template:  Drive—Raked fin for classic longboarding. Ideal Board:  Longboards. Construction:  Fiberglass construction. Chris Christenson designed the Tracker series for bigger boards the way he likes—simplified and basic. There’s a slightly wider base for drive and just enough rake that combines with a thinner tip for a tighter radius on turns and less drag. The 9.0” is more utilitarian and can be used for shorter longboards for driving down-the-line speed, nose rides and smooth cutbacks  and gliders as well.  Fin Specification Size Area 34.59" Height 9.0" Base 6.31" Foil 50/50
