Israelis Shimshon Brockman and Eitan Friedlander won the 1980 World 420-class sailing championship in Quiberon, France.
The pair were champions at the 1972 420 International Yacht Racing Union (IYRU) Youth Sailing World Championship in West Germany, gold medalists in the 1979 470 European Championships in Spain, and bronze medalists in 1983 at the 470 World Championships.
In 1978, Brokman and Friedlander registered the most points in sailing's six top races to capture the 1978 470-class World Cup.
The Israeli sailing team was also gold medalist at the 1976 420s, silver at the 1974 IYRU championships, silver at the 1978 and 1982 470s, and 1977 470 bronze medalists.
Israel's boycott of the 1980 Olympics prevented the pair from representing their country at the Moscow Games.
