1978 FISA Lightweight Championships
The 1978 FISA Lightweight Championships were held in Copenhagen, Denmark from 3 to 6 August 1978. In the history of the World Rowing Championships, 1978 was the only year when the lightweight rowing championships were not held in conjunction with the open men and women event. The lightweight finals were raced on 6 August. The event was held at Lake Bagsværd. In 1978, a fourth boat class was added to the event: Lightweight double scull.
Later in 1978, the open event went to the Southern Hemisphere for the first time and was held at Lake Karapiro near Cambridge, New Zealand.
