I read this book last week while on holiday. It's very well written, and very amusing. I think the pictures are great! And with regards to the "blue" section at the back, the book does carry a warning that says don't read chapter 9 if you're of a sensitive disposition. Needless to say, I turned straight to chapter 9...
The rest of the book is just as good (if not better!). Each chapter has a great intro that tells you about life at sea and puts it all into context for you. Fascinating facts and great little quotes that show how all these phrases are used in everyday life make it very relevant, and not just some boring old jargon.
I'll keelhaul anyone who disagrees with me. And I mean from bow to stern, too!
