How? Well... You obviously won't have a ship here... What about a crew? You must have a crew. Even if they aren't here surely a pirate captain would just form another one while being here, right?

Anyway I bet there must be someone from your crew here. I mean, my world is quite big and full of people and the amount of people I know is reduced but there's one of my friends here. And not long ago there were two more, and we're just normal people. Pirates are more fascinating so logically there must be more here!

[Pause.]

Or at least you should have a wanted poster or something in which it says that you're a captain.
