I studied the magnus effect and then built a rotor ship to test the effects. I tested different sail heights and found that the higher the height of the sail, the faster the boat goes. I also tested different kinds of materials for the sails. I used different grains of sandpaper and found that the larger grains where more successful in catching the wind. Enjoy!
