Hi Mary,
Your post read:
I read that F18 rule the same as two of the "Mikes" in this thread -- doesn't have anything to do with listing brand names in results, as long as you don't separate them out into separate ranking systems based upon brand.
Then you think that listing brand names in the overall results complies with the rule as long as you don't list separate results for Brand A, Brand B, and so on? If that were the intent of the rule, why have it at all?

You obtain the same information just by naming the brand in the results. I'm sorry, but it just doesn't make sense to me.

Just the fact that the information is in the overall results is providing specific rankings according to differing brands, a clear violation, even though it seems to be information many sailors want.
