Rotor sails are relatively insensitive to foul weather and wind direction. If you had any experience with sailing, especialy on the high seas in a variety of conditions, you'd have a much better understanding of the problems. If you have the means to go out on the sea in a sailboat, I highly recommend it. Especially for someone with a STEM background, it's actually a quite interesting activity.
