Raft:
“The origins of the raft are simple: take a man standing on the bank of a river. He falls in but he doesn’t know how to swim. If he grabs a stone he will sink but if he hold on to a large enough piece of wood it will support him. Next we take a man climbing on to a floating log. He notices that it rolls so he tumbles back into the water. But if it has a big enough branch or a smaller branch that falls across another log, he will be able to stand up. This is a basic raft. If this raft consists of two logs separated by a distance like an outrigger, the resistance is much less if the wind is blowing on the sides. Therefore it will move in that course since everything goes in the direction of least resistance.”
