It's all about getting and in the long term keeping more boats on the water in each rig cool . After all who wants to sail a Nationals with less than 10 boats in it frown , when there are boats sailing at the same time in other rig formats that you could be racing against smile . To me holding the Nationals for each rig variety on different days can only increase fleet numbers and that has to be good grin .

As for worrying about pot hunters sick you could have a rule that you can only win one National Title if that makes people feel better cry.
