Posted By: AngusI guess this does require a little explanation. The CEO of Artemis explains that the boat will do 30 kt in a 10kt breeze, which doesn't sound unreasonable for a foiling cat. He then points out that if you put it in a river in still air, the river flowing at 10 mph (notionally - pretty fast for an actual river), then the boat will see a breeze of 10 kt in the upstream direction from its drift. It can thus sail at roughly 30-10 = 20 kt upstream, give or take small factors for angle.
What do we think?

Posted By: AngusThat would be about 30 degrees to theapparentwind. But these foiling cats can exceed the wind speed quite easily. So the true course will be quite different from 30 degrees off the true wind. Interesting problem, isn't it?
