Bump..
The fact it is a "Worlds" type event means it goes without saying the racing needs to be as complete and organized as possible of course. Here I have no doubt the Zandvoort crew will put togehter a top notch event.
For me personally I go to these events to hang out with old friends and meet new ones. My least favorite events have been those where the competitors show up to their boats, race and then head out on their own or with their clique. No real formal organization is required (and you really do not want me doing karioke) but a seriers of casually scheduled reasons to keep everyone together, meet the different personalities from around the world, discuss sailing or whatever.
