Of course, English is the official maritime language. French is by no means important although some of their terms are still there in abbreviations like Cv which comes from “Cap vrai” (means True Heading in English) and others.
But apart from that, English persons probably don’t know the French terms, while the French HAVE TO know the English terms.
Even the Russians need English speaking sailors among their officers. Although, in an exercise with the Italian Navy, the Italians complained about the bad English communication by the Russians. (and very few Italians speak Russian I guess).
