Both nations were again competing for the top spot in heat one of the men’s quadruple sculls, after fighting it out in the discipline at the last World Cup meeting, with The Netherlands winning by a fraction this time.

Three of Germany's Olympic eight crew that took silver in Tokyo were part of the team today, as they rowed to a comfortable heat two win in the men's eight.
