If Michael does that, he'd better hurry. I don't think the Others (or whoever they are) will be at the dock/beach area very long. Since it appears all Michael ever saw of their homes were the shacks and pretend hatch and Sayed's visit confirmed that it wasn't their true home, Michael won't know how to find them at least not without being detected.
