Hi Bertrand and welcome!
Your site is great -- my French is much
worse than your English, but there are some web sites that can help:
The translations are not very good, but they can help to get some understanding of what's on a web site. If you go from French to English they translate Pneu
when it really means an inflatable boat!
I will add your site to the RIBnet links page next time I do an update (which should be soon!)
