They sailed freely,with enough water, but they were still low,so they compromised on one drop a day. Odysseus was watching the sea,when he heard something,and saw something beautiful. They were sirens,birds in the formation of beautiful women,that men can not resist. However once the sirens lure them in,they kill the men. Helen and Penelope tied Odysseus and Mentor up and sat on them to make sure they would't attempt to break away,and head for the sirens. Penelope swung at the birds,and killed the first sirens,then the second, then the third. Then,their boat sprung a leak. They patched it up,ready to give up,when they saw something.
