Captain Fin Christenson Tracker Fin 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 8.5” Tracker is for flatter rocker boards and extra long (11’) gliders. 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. The 9.5” is for noseriders where you need a little depth and drag for noseriding.
