Hi There
I'm not sure what Aussies would say to be honest, I've just sailed in the Taipan State Titles, which is a category C event. The most signage on a boat I saw was, GOODALL YACHT SAILS in big letters on a big head Taipan main, which was on the mast of Garys FCA Blade, other than that just a couple of AHPC website stickers.
Regards
