Anyone interested in a more complex and realistic examination of the economics of pirating should consider Peter Leeson's book, The Invisible Hook: The Hidden Economics of Pirates.
I would also recommend Leeson's Anarchy Unbound: Why Self-Governance Works Better Than You Think for some interesting applications of game theory in more realistic historical contexts.
It's a pretty accessible pop-econ book with a compelling premise and a good amount of historical examples and citations.
