FISA, the International Rowing Federation, did not recognise East Germany as a country and insisted on one German team per boat class. The women, where East Germany was the dominant side, held their selection trials at the Olympic regatta course in Grünau in East Berlin on 24 and 25 July 1964. West Germany did not contest the coxed four and coxed eight boat classes, and Karen Ulrich-Wolf won the single scull competition for the west as expected. East Germany won the competition in the remaining two boat classes – double scull and coxed quad scull. The negotiations about the 1964 rowing competitions for men were even more protracted than usual as not only did a way forward for the 1964 European Rowing Championships had to be found, but rowing at the 1964 Summer Olympics two months later was also on the agenda. The negotiations were led by Willi Daume and Heinz Schöbel, presidents of the national Olympic committees of West and East Germany, respectively. In June 1964, West Germany insisted on one set of selection trials covering both the European and Olympic competitions. The tensions eased when it was agreed on 10 July that there would be separate selection trials for the two international competitions. It was agreed that some boat classes were to compete at a West German regatta course, and the remaining boat classes would meet at an East German venue. Four boats would start per race, with two for each country. The winning country would then be free to nominate rowers of their choice for that boat class, i.e. not necessarily those rowers who had won the race. Compared to the women, the situation was opposite, with West German rowers historically dominant; in 1963, they had won all boat classes. The trials for coxed pairs, double sculls and coxless fours were held on 1 August at the Olympic rowing venue at Grünau in East Berlin, with East Germany winning the double scull race, and West Germany the other two classes. The following day, the remaining trials for single sculls, coxless pairs, coxed fours, and the eights were held in Duisburg. East Germany won in the single scull and the coxed pair classes; three qualifications compared to West Germany's four was the best East German result yet. At a FISA meeting held in conjunction with the 1964 men's regatta, the East German rowing association asked for separate German teams to be allowed to compete in future. Like at the previous meeting in 1963, the motions was voted down.
Medal summary – women's events
The Soviet Union was, once again, the most successful nation in the women's events, with three gold medals.
The table shows the aggregate results for men and women with East and West Germany counted as separate countries. The overall winner was the Soviet Union with six gold medals, followed by East Germany and then West Germany with three and two gold medals, respectively.
