Don't know what you need to apologize for ....

..you, Kevin and the Melbourne Yacht Club ran a great regatta! As far as I can tell, none of the competitors said anything about the boat setups being unfair (perhaps not optimal for conditions ... but then you'd have to change after every race to make that happen and that's not realistic).

...and who knew it was going to blow 18-20kts + for the week! Forecast for early in the week was little to no wind gradually picking up!!!

Great job!
