Problems with 6.5 metre an Ton classes 1900 

Salut Ned ! Please have a look to [[fr:Jauge Godinet] about Ton classes in Olympics 1900, and fr:6.5m SI for 6.5 Metre which is not according to International Metre Rule, but to a french rule (Jauge chemin de fer) (Railway Rule) which became international rule, but not Metre Rule  just before Olympic games 1920. I hope you can use references of WP:Fr articles.
