Navigation in Shallow Waters
This publication is a guide to ship handling in shallow waters and the differences that may be experienced when compared with deep water conditions. It contains theoretical and practical information for ships navigating in open water and in confined channels.
This publication is a guide to ship handling in shallow waters. Drawing on feedback from full-size vessels and ship models, it examines the specific challenges that are experienced in ship performance when navigating in restricted waters. It uses worked examples to analyse risks and to highlight best practice techniques.
This publication, by Captain Eduardo Gilardoni and Captain Juan Presedo, covers many aspects of ship handling in shallow waters. It contains theoretical and practical information for ships navigating in open water and in confined channels.
The publication relates specifically to vessels in shallow waters because feedback from full-size vessels and ship models has consistently shown that ship performance is much less efficient in shallow water than in deep water. It is, in effect, a risk analysis that examines possibilities of ship accidents and discusses methods of prevention.
I am pleased to see numerous references in this publication to my work on squat and interaction, and particularly as it is applied to the practical aspects of navigation and ship handling. The authors aimed to cover a gap in the existing texts relating to ship handling in shallow waters and the differences that Masters may experience when compared with deep water conditions. They have certainly succeeded in doing so.
I strongly recommend this publication for those ashore and on board ship and as
an introduction for maritime students. The text, methods, diagrams and equations are easy to follow and understand.
Finally, if you are a student, good luck in your maritime studies. If you are either sea going or shore based, best wishes for continued success in your chosen career. I hope that this book will be informative and of value to you.
