ISAF just confirmed F18 World Council and say no entire hull painting but polyester gel coat finish only.
Not less than three files in 2 days: interpretation doc to prepare the amendment and updating class rules:

Then you ask ISAF: "hey, look my entire hull painted, it's ok because only routine maintenance, isn't it ?"

Good luck indeed Macca... ISAF has been crystal clear on your last asking (the first document), it's hard to believe that they now will say "Yes, what we write is without any importance, it's not big deal, do what you want..."

This rule (as other one) can be changed but with one year notice, in order to be fair.
All the boat maker playing same game.
