Wim van Duyl

During the Olympic regatta of 1964 a controversy emerged between the team members (Van Duyl and Jongkind) of the Dutch Dragon resulting in Jongkind leaving Japan after the second race. After the Games the Koninklijk Nederlands Watersport Verbond banned them both from competitions for two years.
