Great, thanks for the answer! You mention differing wind speeds at different heights. How about that? I've often wondered. I assume airflow is...
Looking at designs with multiple sails such as Crossbow II, LongShot and the Hobie Trifoiler makes me wonder: Why stop at two sails? Why not 3...
I was reading that iceboats can travel up to 10 times windspeed and can sail at just 7 degrees off the wind. I assume that is possible solely...
