I read this differently than you. I read it that the organizer can't seperate the F18's into fleets or give out One-design trophies within the F18 class.
I don't believe that it is prohibited from listing the type of boat in the results.
I agree with Mike - I don't think this speaks specifically about listing brand name within the event standings. However, sometimes things get a little lost when rules are brought in from different native language speakers...as some of the F18 international rules are. It would be interesting to get the official interpretation of the rule but I suspect it would only be to not establish awards or prestige based on manufacturer within the overall event standings.
i.e. it says we can't RANK sailors based on manufacturer of the boat.
