Twenty sailors are documented, besides the France and Great Britain participants there was a Mixed country team from the US and Great Britain.

For the 3 to 10 ton the 19km (12miles) course in the Meulan course area was used.
The race was troublesome due to an almost complete absence of any wind and the existing wind was perpendicular to the course (river Seine) and blocked or diverted by trees and buildings.
Two separate races were sailed. No combined results were made.
Mixed country teams during the 1900 Olympics are grouped together under the ZZX IOC code.
Initially only the race on 24 May 1900 was part of the Olympic program. However the race on the 25 May 1900, initially part of the Exposition Universelle program, was afterwards awarded with an Olympic status.
