Navigation in Shallow Waters (eBook)

(Excludes any applicable taxes)

This publication, by Captain Eduardo Gilardoni and Captain Juan Presedo, examines 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. The text, methods, diagrams and equations are easy to follow and understand, making it the ideal handbook for those ashore and on board ship, as well as maritime students.

This book 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.
