by Captain Eduardo O. Gilardoni
and Captain Juan P. 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.
