Dorsal has always had a deep relationship and passion for fins being that they are a critical component of board design and performance. Dorsal wanted to bring this to life by launching a fin brand driven by Mark King's vision of performance and eco responsibility. He believes, Dorsal has a responsibility to make fins as eco-friendly as possible and ensure they keep the ocean floor free from “lost and broken fins”.

Dorsal's fins are designed to be screwed into the fin box to secure the base of the fin and allow the hexcore flex patterns to truely come to life. In addition, the fins are also designed to have a tapered base for a tighter fit in the box. Each set is built with a base that is compatible with either FCSII and FCS or Futures.
