Geez c'mon Pweet! There were GIRLS in it. Some of them even finished!

Having said that, it might be that you just got sea sick.
For some reason I start feeling sea sick in about 15 to 20 minutes on a windsurfer in swell.
I don't get sea sick in a boat and I don't get air sick, so I don't now why a windsurfer should be different, but it is.
