Erhard Amon from the Ausseerland continues an old family craft that has been passed down for generations. He builds traditional boats called Plätten that are flat on the bottom, built from natural materials, and true one-of-a-kind pieces.

In this part we learn more about Björn's family and what influence they had on his career as a professional windsurfer.
