Explain how the sixth chapter, “On the Beach,” is a characteristic and fitting finale to Langewiesche’s The Outlaw Sea. 
How does Chapter 6 make sense as the last chapter of the book?  How is the chapter “characteristic”?  How does the subject matter and, perhaps, how does Langewiesche’s attitude fit here as the completion of this book?  Refer to the material from at least two of the other chapters in a substantial way to ground your argument regarding the final chapter in a comprehensive sense of his entire work.
