Time always make things right. Of course you have to have your priorities, but I think you should not be afraid to jump head first into that project (which does sound like an incredible opportunity). You might lose touch with the girl you were seeing obviously, but I'm certain you'll get to meet someone else as good if not better while travelling! I think you should let go and just live day to day, see what happens.

Edit: say you don't like the boat job after all, what are the chances of getting your old job back if any?
