Reviews of Previous Edition: "I found this a useful reference book for both seafarer and student alike, it covers the basics of the subject matter.The text is comprehensive with clear illustrations, which will be of help to the students. The exercises at the end of the chapters are a useful method for the students to test their understanding. The helpful tips and revision aids contained within the appendix should assist those with examinations to pass." Nicola Pryce-Roberts, MSc Programme Leader, School of Engineering, Liverpool John Moores University, August 2002 "Although the title is Ship Stability for Masters and Mates the book will be valuable for marine engineers studying for certificates of competency as well as students. It is recommended for its clarity of explanation and breadth of coverage." MER (Institute of Marine Engineers), September 2000 "Ship Stability for Masters and Mates is recommended reading for all deck officers and would make a valuable addition to the ship's reference library." The Marine Observer, April 2000 "It will prove useful to Maritime Studies degree students when studying the subject, and provide a reliable reference book for those responsible for the stability of ships." Nautical Magazine, March 2000 "This book has everything a good textbook should have. Ship Stability is an invaluable reference for nautical surveyors and chief officers and, indeed, anyone involved with day-to-day concerns of stability." SEAWAYS, January 2000 "In line with the aims of the book, it covers the basics of the subject matter. It is clearly written and the extensive use of illustrative examples will be of considerable help to the student".

Even for those who are not at the mates or masters level, this book will certainly aid you in understanding the basics. A must own book for those who need to understand.' "The extensive revision has improved the value of the book. It can be thoroughly recommended to masters, mates, and engineer officers preparing for their SQA/MCA written and oral examinations. It will also...provide a quick and handy reference to others working in the maritime field." The Naval Architect, June 2006 "...thoroughly recommended to masters, mates and engineer officers preparing for their SQA/MCA written and oral examinations. It will also help ONC, HNC and HND students, and provide a quick and handy reference to others working in the maritime field." - The Naval Architect, 2006
