I think some ships have two, but the reason you can't stuff a bunch in there is the same reason planes usually have only one wing.

- paulsutter 8y agoOh right that’s why ships have only one sail, and wind farms have only one windmill, because same reason as planes. Good point. Where can I see the ships with two?
- satori99 8y agoA sailing vessel with a single sail still has two foils for generating lift. The other 'wing' is the boats keel. It is net force from both that propels a sailing boat forward.
- ouid 8y agomost planes have 5 wings under any reasonable accounting.
- nabla9 8y agoMost planes have only two wings. Wings producing lift and keep the plane up. Two little horizontal 'wings' at the back are horizontal stabilizers. They are like wings but installed upside down (they produce negative lift and push the tail down).
