The Vee Bottom flex is a finger fin. It has a larger base that goes into a narrow body and tip. It also has more rake which all adds up to make an exciting fin that keeps you on your toes.
This fin range comes in a larger size to ensure that enough of your long fin is in the water to keep you in control as you are powering through high-speed turns. The fin is made for wider, flat panel, vee boards, where you have all the speed and want some control without losing that wild looseness that low area fins have.
