Racing dinghies are designed for racing, but not all have necessarily the same calibre of performance as the above. However, in many cases they can still offer equally close competition, at the very highest standards, which for many racing helmsmen and crews is the most important consideration. They cover a wide range, and many are descended from Uffa Fox's seminal International 14. People often "travel" with their dinghies to international races in famous sailing spots such as Lake Garda in Italy. The Snipe International Class still stands as one of the strongest classes, after reaching the status of world's largest fleet of dinghies in July 1936. Other examples include the GP14, Enterprise, Solo, Graduate, Firefly, Lark. A specialized subgroup is the Scow, which typically uses two bilgeboards instead of a centerboard, and may have two rudders. Many racing dinghies require two or more people to sail the boat, the skipper is in charge or steering and the main sail depending on the boat, and the crew is in charge of the jib, the spinnaker,(which can only be flown while going downwind) and keeping the boat level
