How do you return to Islands of Freedom?

I skipped the pirate girl and Kraken boss battle - but now I want to go back.
Can anyone help me? The dirigible is no good.
Thanks in advance.

Talk to the guy on the beach, Kitano.

Or if you are in the dwarven area (Upper/Lower Hadar), you can travel to the Eastern Island by the submarine after sealing the peace treaty between human and dwarf.
