Amsterdam based Westkust is about Open Source Surf Designs. All our fin designs are shared with the world for free. We were the first in the world to build a complete collection of surfboard fins based on 3d print technology. Extensive research has gone into our designs. Our fins have all been tested for optimal hydrodynamics. Fin bases have been designed to fit the world's most popular finboxes. All our designs have been made in partnership with Finfoil software. The world's first fin design software. We are open in everything we do. Always.
