Cool. Thanks for the input.
Maybe I'll run separate start lines on either side of the committee boat, one for cats and one for sailboards.
I'm surprised that windsurfers can be faster on a windward/leward course. I would have figured that they'd be a fair bit slower.
This lake is mostly used by sailboarders and kiteboarders, so we ought to do what we can to include them, if for no other reason then they are in tight with the park rangers. Also, many of them are ex-cat sailors so maybe we can seduce them back.
