Excerpt from an answer about sailing > Why doesn't the sail push directly on the boat? > The reason is that the boat and the sail are not in direct contact. The boat is in contact with the water, but the sail is in contact with the air. > Because the air and water are different substances, they can't push on each other. The sail pushes on the air, but the boat pushes on the water. This means that the sail and the boat can't push on each other. It's late in the night for me or it doesn't make any sense?
