There were 12 boats (60 competitors) from 12 nations, with each nation limited to a single boat in the event. The event was won by East Germany, the nation's first victory after three consecutive silver medals since it began competing separately in 1968. Defending champions the Soviet Union finished second, while Poland's bronze medal was the first medal in the men's coxed four for that nation since 1932. Twin brothers Ullrich and Walter Dießner became the sixth and seventh men to earn two medals in the event, as they had also competed on the 1976 East German silver medal team.
