Derived from the ARROW class. A. M. (Gus) Deering sold the ARROW plans to Dunphy Boat Works, Lake Geneva, Wisconsin who renamed the boat the CONDOR. The only variations from the ARROW being a revised sail plan plus the boats were built with a choice of centerboard, fixed keel or CB/keel. They were also available with a transom mounted rudder.
