Can You Escape From The Sea

You were forced to go to sea to get food for your family. The weather was clear, but when you sailed away from the shore, a violent storm struck. You have not seen such a wind and such big waves. Your boat is not designed for this kind of weather, and you roll over. You were thrown into the sea, and then, you hit the seabed. You are still alive and you need to find a way to escape.
