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 as it is the longest serving dinghy in the Olympic Regatta. It currently fills the slot for the Heavyweight Dinghy at the Olympic games. It has been contended that the Finn is the most physical and tactical singlehander sailboat in the world.
