Shiphandling - Passenger Ships Without Tugs
Commodore Nick Nash shares his extensive knowledge and experience gained from nearly twenty years in command of cruise ships.
The book covers the ‘mechanics’ of handling a large cruise ship and has primarily been written to help aspiring cruise ship captains to master the art. However, it will also be a useful source of reference for more experienced officers.
The book discusses:
- Ship’s equipment, including propellers, rudders and thrusters. podded propulsion systems, the rate of turn indicator and radius track control systems
- Shiphandling theory, including berthing and lifting-off techniques, the pivot point, drift angle and Bernoulli’s theory as it relates to ship squat and interaction
- The effect of wind and current and how to calculate the forces on the ship
- Stopping techniques and emergency anchoring.
The appendices include numerous approach/departure plans for ports around the world, based on the author’s own manoeuvring notes. Each port is illustrated with annotated route charts and practical guidance notes.
Captain Nick Nash has written a much needed practical and informative book on how to manoeuvre large modern passenger vessels and ferries that have multi-engines, rudders and thrusters. He has also included a chapter on handling ships with POD propulsion.
To be able to handle a large cruise ship in a safe and efficient way, you have to understand and have knowledge of the ‘controllable’ and ‘uncontrollable’ forces that can affect a ship. Nick has gone into both these forces in detail, making this book a useful reference for all who handle or aspire to gain competence in handling ships.
The book usefully has an appendix of over 50 manoeuvres (including notes and diagrams) taken from Nick’s own experience manoeuvring large (290 m+) passenger vessels in the most popular cruise ports of the world while he has been in command over the last 15 years.

(Posted on 04/07/2019) Cruiseships keep getting bigger and bigger and, as some incidents have served to demonstrate, the consequences of accidents have increased exponentially. This clear and thorough 361-page book therefore makes a significant contribution to the cause of safety, providing insightful guidance based on the practical experience that Capt Nick Nash - a serving master with Princess Cruises and a training captain at the CSMART Centre - has gained in almost 30 years of cruise ship experience, including the last 14 in command. Aimed in particular at those serving on vessels of 70,000gt and above with twin-screws, twin-rudders and multiple thrusters, the book draws from his manoeuvring notes and is liberally illustrated with relevant photographs, diagrams, charts and actual approach and departure plans for some of the most popular cruise ports around the world. Capt Nash gives four 'top tips’ for prospective shiphandlers in his foreword -on positioning, speed control, patience and keeping one hand in your pocket (so as to use only one hand on one control lever at a time). However, his 361-page book leaves no stone unturned in its comprehensive guidance. Subjects covered include: the pivot point; propellers, rudders and thrusters; podded propulsion systems; squat, interaction and bank effects; rate of turn; the impact of winds and currents; controlled and crash stops and emergency anchoring; and issues such as berthing and lifting-off techniques, and drift angles. Along the way, Capt Nash throws in some fascinating case studies, telling the reader how not to do it as well as how best to do it, as well as devoting a whole chapter to detailed advice on making the best use of a radius track control system. Another very important section covers the rate of turn, stressing the importance of good monitoring and the way in which local environmental conditions can have a dramatic effect upon plans. Capt Nash also gives some useful advice on how to avoid the risk of heeling during the tight turns that cruiseships sometimes have to make. Produced to admirably high standards, the book Is clear and direct and excellently presented. Whilst it is primarily intended to help new and aspiring cruiseship captains, it contains much of relevance to all ship handlers and deserves to become a standard reference work for many years to come.
