Pipe down Mate!
While beach catamarans are more popular as leisure/fun sailboats compared to trailererable and affordable monos, the guys that sail at the Olympic level multihull are just as serious as the mono sailors. Yes, it is a smaller group of sailors but why eliminate them from competing? Is it pure politics? What is the motivation to drop cats from the program? The dinghys don't provide any more action than cats do.
I think it is just the elitest attitude of the mono sailors in charge that is "back door politicing" to have their way.

I have seen dinghy sailing on T.V. I would rather watch fishing.
