Stuck Underwater in East Freeport
 

There is a boat underwater near the low pier of the docks (right next to the barbarian). If you swim on top of the boat and right click it (take control of the helm) is states "You control the helm, captain" and from that point forward you cannot swim past the surface layer of the water. I swam as high as I could and sat down and it pulled me above the surface. Im pretty sure we aren't ment to get stuck underwater... :)
