The OA put it in, presumably because the class wants it. I guess time will tell...
I am a huge fan of the trapezoids, especially for multiple fleets sharing a course. I sort of talked the HCA into it for the NAs in DE a few years ago, it got mixed reviews, probably because it was so new (and requires lots of good resources).

Without a doubt the trapezoid course places additional demands on the RC team and competent support is a must to make it work. The course takes a lot or realestate but WOW what a great course for the sailors and when the breeze and seastate kicks up it is an absolute hoot for the sailors! The pucker factor kicks up a notch when the boat 3 meters above or below you eats it. That double trapped spin reach to the other side can really thin the herd. In my opinion it is a must for big fleets and Worlds type of events. It gives you an opportunity to exercise every skill you have in the toolbox. GO TRAPAZOID :-)
I'd be curious to hear negatives of the the trapzaoid course.
