These Future 438 Quad fins are a medium sized fin and are designed with Futures Vector 2 foil.

Vector Tech Foils were developed for the specific purpose of creating maximum speed and kinetic drive through the turns. Based on the physics that create lift on an airplane wing, the fins produce high power (lift) with drastically decreased drag. All the Vector series fins combine different force foils in one fin outline, one at the base of the fin and one in the tip. Vector II has a curved inside foil at the base that blends into a flat side foil at the tip.
