The following titles are included in the ‘Passage Planning Guidelines’ trilogy:

  • ‘Passage Planning Guidelines’
  • ‘Safe Nav Watch’
  • ‘Teamwork on the Nav Bridge’

‘Passage Planning Guidelines’ focuses on the Appraisal and Planning stages of voyage planning using traditional methods, paper charts and ECDIS, with fully worked examples throughout.

The 2023 edition has been updated to reflect the industry’s changing position on using ECDIS, and ENCs, as the primary means of navigation when passage planning. While still covering all the aspects of traditional paper chart navigation, this edition also includes a detailed overview of passage planning using ECDIS. Passage planning calculation examples are included to increase navigators’ familiarity, and imagery has been updated for both paper charts and ECDIS route planning examples.

‘Safe Nav Watch’ provides guidance on safe navigational watchkeeping, highlighting potential hazards and how these can be avoided. The book contains guidance from experienced mariners, reinforced by best practice.

In this edition, all applicable SOLAS amendments and bridge equipment performance standards have been updated, alongside an in-depth review of the ‘Bridge Equipment’ chapter. New case studies have been added to the ‘Lessons from Navigation Incidents’ chapter, highlighting errors navigators have made on voyage and what the industry best practice is to prevent incidents from happening again. Chapter 5 – ‘Bridge Practices – Weather’ has also been expanded to incorporate tropical revolving storms, their locations and how to navigate safely when one forms.

‘Teamwork on the Nav Bridge’ is based on original text from a leading trainer of cockpit resource management. The text has been fully revised and updated to reflect the key factors in bridge resource management, and why this is essential when forming the bridge team.
