The author relates first hand experiences of sailing on these ships (either from his own experience or he quotes from historical accounts).He gives information on the strengths and weaknesses of the various types of ships and discusses the technological changes that helped free ships from being so dependant on the winds and currents.

This book cover ancient ships all the was up to modern ones.At the front of the book is a picture of sailing ship with the names of all the sails and parts.At the back is a marked picture of a steam ship. Near the end of the book, he also explains the basics of boating and what to look for in a sailing or motor boat.

This was exactly the type of information I was looking for, so I thoroughly enjoyed this book.I found it an informative, easy read.
