There is no mention of club flags or association flags, and no sign of them in any picture that I looked at. Boats (?) are identified, like racing sailboats, by a combination of national code and individual number, affixed to the upper part of the sail. The national codes, of one, two, or three letters each, seem to be a development of the set formerly used by (I'm relying on memory here) the International Sail Racing Federation, which has replaced them by a set of all three-letter codes, which is not ISO3166-compliant. National organizations participating in the Federation International of Sand and Land Yachting (FISLY) are (except in one case) represented in its website by abbreviations that do not conform to FISLY's own code set.
