The main objective of the present publication at the time of its release was to acquaint students with the major rules and most common problem in marine navigation. It was expected to be of the practical use when carrying out their day to day activities on board vessels. The theory of navigation is presented using the short definitions. The whole experience of the author has been reflected in the pages of this volume.

Numerous problems of navigation have been covered. One of the remarkable features of this book is that the author made every effort to avoid digging too deep into the theory so that the reading and understanding the subject is easier to the people with no background. All of the terminology used in navigation has been covered and explained in detailed.

Moreover, the information has been presented in the way making it very reader-friendly – each of the articles deals with some particular topic. For example, there are articles on compass adjustments, ship’s business, arithmetic of navigation and o many others. This approach used by the author guaranteed the popularity to this book and this is the main reason why it is still used today, more than one century after it had been first published.

When we thing about the number of the good titles devoted to the problem of marine navigation, available today, it appears that most of them are discussing the subject from the more or less same angle. In fact, the ultimate aim of the authors of most of them is to give readers some essential instructions. This book, in contrast, was prepared for those who carry put their work by rote and would like to know more about the basic reason and foundations of what they deal with during their day today activities.

It will also be great for the people willing to extend their knowledge horizons. Many of the points covered in the pages of this volume, have been intentionally repeated, as desired by the author, who wanted to closely follow his line of thought. Such an approach was aimed to let people understand the material easier. In fact, the book was supposed to serve as a supplement to the well known American Practical Navigator publication, but it will also be useful when used separately, as a textbook.

This one used to be very popular book one century back and the contents is still actual and interesting to all future navigators as well as to the practicing professionals wanting to get better and deeper understanding of the subject.

One of the oldest volumes available here. The book is devoted to the application of the science of trigonometry to the marine navigation. Note, however,, that regardless of the title of this publication, the readers are not actually expected to be excessively proficient in the trigonometry or mathematics. Every effort was made by the author to present the subject in the maximum intelligible manner.

The content of the book is arranged in four big sections, starting with the section on plane trigonometry covering the functions of acute angles, goniometry, right triangle, oblique triangle plus numerous examples and tables. The second section covers the spherical trigonometry together with all its application.

The third section of the book deals with the surveying matters, particularly triangulation, land surveying, levelling etc. finally, the closing section of the publication addresses the navigation, including the sailings and nautical astronomy, and all definitions normally used in the field. The book will be of particular interest to the collectors of the ancient books on marine navigation and to all those willing to know more about the underlying concepts of the navigation.

The present publication can be used as a supplementary training material for the students of marine navigation. All of the information contained in the pages of this volume have been carefully selected and duly arranged. The book starts with the list or recommended abbreviations and terminology commonly used in the field of navigation. Then, the first section of the main part of the book is dealing with the terrestrial references including equator, geographic poles, meridians, parallels etc.

After that, three chapters come addressing the celestial references, figure drawing for the astronomical calculations and preliminary calculations. The use of the traverse tables has been discussed within a separate chapter and same applies to the Mercator chart. Note that there are numerous exercises included by the author to facilitate good understanding of the subject. The correction of the latitude has been described from both theoretical and practical point of view.

Among the important topics covered by the author there are also chronometer time, theory of astronomical position lines, graphical combination of sights and so many others. There are also worked examples added to the text part of the book.

To all newcomers to the world of the marine navigation, it usually seems as a sort of magic, incorporating countless data tables, formulas and strange names. Many people working on board ships as navigators have quite limited knowledge of mathematics and that is the fact. However, the navigation by its nature is rather mathematical subject and this is the way it should be actually taught.

Moreover, this is why a good understanding of mathematical concepts shall be possessed by all navigators. Note, however, that the author of this book did not o too deep into the aspects of trigonometry or spherical geometry under assumption that these could be avoided. The book is quite compact so it will not take too much of your time to address every single chapter of it, but the benefit offered by the contents are really good.

Taking into account that the mathematical foundations of the science of marine navigation remain unchanged, we do encourage all people involved in handling marine vessel to pay close attention to the information presented in the pages of this volume. It will also be interesting to the practicing mariners including those using the electronic navigation means – it is always good to know the essentials.

The passage plan shall be prepared for all vessels and it shall cover the complete voyage starting from the berth of departure and up to the berth of the arrival. Subject plan shall be prepared in strict compliance with the recognized international/national standards and to the standing orders of the shipping company. The content of the plans shall also be following the navigational practices and standards established within the SMS, i.e. safety management system of the company.

The vessels of particular company will most probably use the same format when preparing their passage plans, though the variations commonly cause by the types of cargo and of the vessel, as their as of the commercial agreements are also possible. The passage plan that has been used within this publication is not compliant with the instructions of any specific shipping company and has been presented to serve as an example of preparation. The passage plans usually differ with their layouts.

Generally, the documents specific to the particular shipping company are used when preparing the voyage plans. The authors of this work have used the general layout for the plan, balancing on the information on the charts with the other documents relating to the passage plan. Do not forget to use all documents related to the passage plans together with the navigational charts...

A constantly increasing number of the merchant vessels find themselves chartered to operation in Arctic waters, creating a real and significant demand for the newly constructed ice-classed vessels. Subject requirement is commonly applicable to the vessels that operate in the low temperatures or in the iced waters, with their crew duly trained to man such sort of vessels, and it has already brought about by numerous factors including likelihood of the shipping trade routes that are opening up in the Arctic region, coming on-stream of the terminals in northern regions, and a significant increase in cruise traffic in Arctic region.

All above mentioned factors are directly contributing to the requirements for the ship crews to have access to all required and available technical knowledge from the ice pilots and navigators. Operating a vessel in iced sea required higher standards of training combined with the practical experience. This combination will allow the required development of the skills and professional knowledge and proper understanding in order to competently and efficiently manage the safe passage of the vessel.

Safe navigation of the vessel in ice comes as a result of the experience in the winter navigation combined with the ability of the crew to perform the proper interpretation of the available reports and select the best route on the basis of the behavior and characteristics of the ice...
