Finn

The Finn dinghy is the men’s single-handed, cat-rigged Olympic class for sailing. It was designed by Swedish canoe designer, Rickard Sarby, in 1949 for the 1952 Summer Olympics in Helsinki. Since the 1952 debut of the boat, the design has been in every summer Olympics, making it one of the most prolific Olympic sailboats.
