The U23 Small Boat Trials (KBÜ) are the U23 national coach’s last major test before the German Championship for top rowers aged 19 to 22 from all over Germany in singles and doubles.

The KBÜ is an initiative of the German Rowing Federation (DRV) and serves as a basis for the U23 national coach for squad nomination and review, as well as for filling the national team boats. The AAC/NRB has been the organizer of the KBÜ for many years.
