The Easter Regatta at Gippsland Lakes YC will be incorporating the first F16 Australian Titles this year. So for the Mozzies with spinnakers there should be some Blades, Vipers and Taipans to race against.
The Notice of Race for the F16s is attached. I don't have a NoR for the Easter regatta yet but the OTB schedule should be much the same as for the F16s.
