Ship Navigation

Ship Navigation


Ship Navigation demonstrates the art and science of navigating a ship from departure to destination without hitting the shore or shoals. There are essential decisions which need to be made every day in navigational work and the book provides guidance on how to make the right choices. Ship Navigation does not require any prior knowledge of the subject from the reader. It starts at the beginning: the first chapter is devoted to definitions and an overview of the challenges facing the navigator and ways of solving them.

Both traditional and modern methods of navigation are discussed. An analysis of investigations into recent incidents of vessels running aground or colliding indicates that there is still a demand for 'traditional' methods.

The text deals with navigational problems and methods from a practical viewpoint and contains many pictures and step-by-step diagrams. This makes it easy for the reader to understand not only the theoretical aspects of the problem at hand, but also the situation when actually on watch.

In spite of - or perhaps because of - the abundance of sophisticated electronic navigational aids available today, the human factor is still recognised as a major obstacle to safe navigation. The author has provided numerous examples from accident reports and investigations which illustrate how this unpredictable element impacts on watch keepers and their ability to navigate safely at all times.

The excellent text written by a Master Mariner with many years of watch keeping experience on the high seas and coastal waters, combined with the excellent colour and black-and-white illustrations makes this an essential source of reference for every student of marine science. It will also be useful to many practising deck officers who want to keep up-to-date with the theory and practice of their profession.

Ship Knowledge

Ship Knowledge


Ship Knowledge will tell you everything you want to know about ships and shipping. The book covers all the components and systems that make up a modern ship in detail, from design drawings to the finished products, including paint systems and legal requirements.

The detailed description of the various subjects, along with many drawings, cross sections and colour photographs, is presented in simple terms, making the content accessible to everyone with an interest in shipping.

The book will enable you to see the ship not just as an object, but as a completely independent operating unit, where the modern techniques applied are similar to those used in a medium-sized city.

Ship Knowledge is ideal for use in maritime and shipbuilding schools, as well as providing a valuable source of knowledge and reference for professionals involved in modern shipping.

The Colregs Guide

The Colregs Guide


The 'Regulations for Preventing Collisions at Sea' (basically, 'Traffic Rules at Sea') should be essential reference material for every seafarer. Surfboarders to super tanker crews should all have the same knowledge and interpretation of the rules.

This book uses photographs and computer graphics to define the meaning of navigation lights for different kinds of ships in. It also illustrates how to apply navigation lighting, using a top view and a view from the bridge of the vessel concerned.

The book is a useful tool for study at all levels of marine training. It is also suitable for sailors of pleasure craft, who can use it to learn the meaning and content of navigation lights and apply them to their own vessels.

Ship Stability

Ship Stability


Everyone might have an idea about what constitutes a stable personality, but actually defining it is difficult. The same applies to the concept of a stable ship. Nevertheless, the term 'stability' is still applied to all types of vessels in many regulations.

Stability affects the safety of the ship and its crew, as well as the environment. Therefore, it is essential that each crew member understands the meaning of stability, irrespective of their position or which type of ship they are working on.

In this book, the concept of stability is defined and visualised in a way that makes it accessible to everyone. Some topics are dealt with in detail, but they are still easy to understand, even without prior knowledge of the subject.

Ship Handling

Ship Handling


The book is divided into three sections. The first section describes the features of a ship and the different methods of manoeuvring it. The second section deals with the forces which influence the movement of a ship and the final section describes the factors which affect the ship during manoeuvres (mooring, sailing in shallows, manoeuvring in the docks, etc.). The emphasis is placed on external factors which can influence the manoeuvring characteristics of a ship. The initial approach is at a basic level, suitable for pilots in training, for example. The field of ship dynamics is then explored in more depth for seafarers with a greater knowledge of the subject.

The book analyses all aspects of the manoeuvring features of ships on both open water and narrow waterways, with reference to the recommendations of the STCW Convention, which sets out the required manoeuvring abilities of helmsmen.

Author Herve Baudu is a teacher in maritime training who has 15 years' experience working on board ships, achieving the rank of captain. He taught manoeuvres first at the 'Ecole Navale', then at the National Maritime College of France (ENSM) in Marseille.

The book is intended for both students in maritime education who are learning basic manoeuvring skills and seafarers with extensive manoeuvring experience who want to expand their knowledge in this field.

Ships' Electrical Systems

Ships' Electrical Systems


Ships' Electrical Systems deals with all types of electrical installations on ships, from the basic design of the system to power generation, distribution to consumers, automation, remote control, nautical equipment and communication systems. Relevant work in the engine room and the bridge and the influence of the system are discussed.

The book is intended for use by those with a good knowledge of electrical systems on land or with a limited knowledge of electrical systems on ships. Onshore electrical systems are divided into power generation, power distribution, switching and distribution of low voltage and each system is dealt with by a specialist in that field. The technical officer responsible for the electrics on board will be required to understand the complete system. The book sets out some basic principles of electricity and describes the specific requirements for ships.
