|Date||7 July – 4 September 1920|
|Location||Oostende / Buiten-IJ, Amsterdam|
|Participants||5 from 1 countries|
|Format||Three races, with final places decided by total points. Point-for-place scoring for each race.|
The 12-foot dinghy class had to be completed at a later date, after a controversy involving the course. The two crews were from The Netherlands, so acceding to a special request by the Belgian Organizing Committee, the final two races were moved to the Netherlands and held in September on the Buiten-IJ near Amsterdam on 4 September.
