I had a mission to get a jade amulet. I had to fight the trogies and "pull the plug" to drain the water. To pull the plug, I had to activate towers.  Then I went to the flooded temple and fought Fin the Cutthroat. I won that battle and then I went to the pirate leader. He gave me a "ship" that is out at the dock. At the dock, I found out that my boat was a rickety, old raft. It looked pretty bad, but at least it was fast.

Good luck, pirates!
