John Rousmaniere has created a comprehensive text on the sport of sailing and seamanship which is enjoyable to read and very authoritative. By their nature, sailors have strongly held opinions on most subjects, but virtually every sailor I know of who has read John's book holds it in very high regard. The illustrations are clear and not too busy to get in the way of showing the frequently complicated topics which are inherent in the sport. I also find that Seamanship is not just a repeat of tired old sailing methods of 30 years ago, but rather integrates the classic techniques (storm tactics, navigation) with the modern (Crew Overboard Recovery, modern anchors and electronics).I highly recommend this book, and encourage anyone to buy it if they want to improve their sailing skills.
