Hey Dan -
We had four of them and we did six races, I think. We put the newest sails on the oldest boats to try and even things out a little, though none of these were ragged out - I've seen boats in much worse shape than these at Nationals. If I recall correctly, the newest and the oldest boats were fastest. The newest had the racks, which made everyone moan about the weight initially.
I hope it doesn't come off like I don't like the Wave - I do, very much. I was just trying to make a point, albeit poorly, that in my opinion, there is an awful lot of variation within what is considered a multihull one-design. Not just the hardware and the sail, either - it's not intended as a criticism, just an observation.
