I have been cruising in many different areas around this beautiful globe and I find this dictionary to be one of the few available on the market. The book is divided up in to catagories such as the hull, deck, navigation, commands, refrigeration, engine etc., although I am fluent in French and German, this book aids me immensely to navigate through the seaman's language in 10 different toungues. Sailor's terminology can be rather intimdating to some people in their own language, let alone in another foreign language. I you are planning a cruise around the Caribbean, Mediterranean, South America or Africa buy this dictionary. The only negative part about this book, is that it contains no middle eastern or far eastern languages such as Arabic, Persian, Thai, Chinese, Fiji or Indonesian. If they would have added these languages to the book, it would have been too combursome to use hold the dictionary.
