Oh man, there's so much good information in here, and so many good ideas that it's hard to know where to start. If a GM were to design a New World for sailors to explore, they should look no farther than the ideas in this book. There may be reprinted material (Straits of Blood), but it's all good. The other strange thing I discovered about these Swashbuckling Adventure books (as opposed to the old school 7th Sea) is that they seemed to have been made in a hurry...this book, Explorer Society and Cathay all had a huge amount of typos. Still, great book full of great ideas.
