In this second edition of Ship Stability Part I, ten chapters have been added, by transferring them down from Ship Stability Part II, to adequately cover the syllabuses for:-
1) Officer in Charge of a Navigation Watch (formerly called Second Mate Foreign Going);
2) The FY & SY BSc (Nautical Sciences) degree courses of the University of Mumbai;
3) The FY & SY BSc (Nautical Sciences) degree courses of the Indian Maritime University;
4) The three-year BSc (Nautical Technology) degree course of the University of Mumbai;
5) The one-year Diploma in Nautical Science (DNS) course of the Indian Maritime University.
This inclusion of ten more chapters here was needed because some topics like Cross Curves of Stability, Trim, etc are now part of the DNS course. Simpsons Rules are in the Mathematics syllabus of the first semester of DNS Course. Hence that chapter also has been brought down to Ship Stability Part I.
I was pleasantly surprised when many Marine Engineers said that they found the Stability books in the Nutshell Series very useful.

SHIP STABILITY III NUTSHELL SERIES BOOK 6
PREFACE TO THE SECOND EDITION
The subject of Ship Stability for mariners has been covered in three parts.
In this second edition of Volume III, eight chapters have been added, including Parametric Rolling, Squat, Under Keel Clearance, & Draft Survey. These named topics are of current interest to mariners as they are required to know these while complying with their ship owner’s or ship operator’s ISM manuals.
While writing this second edition, a policy change has been made in Stability II & Stability III. Earlier, the numbering of chapters through all the three books – volumes I, II & III – was continuous. Now, each volume starts with its own chapter 1. This makes way to add chapters in each volume, at a later stage, if found necessary
As far as possible, a practical approach has been maintained to enable ship’s officers to put the knowledge to practical use on board ship.
Many Marine Engineers have thanked me saying that they found these three Stability books, in the Nutshell Series, very useful.

SPHERICAL TRIGONOMETRY NUTSHELL SERIES BOOK 8
I have often been asked how long it took me to write a book in the Nutshell Series. The reply `About eleven years' usually evokes a look of disbelief. I would like to clarify this statement. It takes about five years of teaching a subject to understand it well and another five to understand it thoroughly. A fairly large number of students in each class has the advantage that more doubts and questions are asked by the students. Different approaches to teaching the same subject can be tried out over a large variety of students and the effectiveness of each approach evaluated. Thereafter, it takes about a year to write the book, late into the night, after working full time in the college.
Like the other books in the Nutshell Series, I have attempted to simplify the subject to make it easy and interesting. Spherical trigonometry is a `servicing subject' i.e., one which enables a student to under-stand another subject. Spherical trigonometry is studied by mariners so that they can understand the practice and principles of navigation. I have carefully divided the subject into parts so that, after studying for about three quarters of an hour, the student is given an exercise to work to test the knowledge gained by him in that chapter.

MARINE METEOROLOGY NUTSHELL SERIES BOOK 2
Meteorology can be a very interesting subject if tackled properly. The secret is the order in which the topics are studied. Everything would then seem to fall into a proper pattern whereby nothing needs to be conned by rote (learned by heart).
Meteorology is a vast subject and there are many books on it. However, this book is meant to give the mariner the necessary knowledge in a simple and concise manner (in a nutshell!), enable him to become competent with less effort.
The sketches and maps have been personally drawn by me and simplified to make the subject easier to understand.
In this edition, the third, minor changes have been made throughout especially in the weather reporting system, the various weather codes, meteorological instruments, the International Ice Patrol and weather routeing with cross-references, wherever necessary, to the 2000 amendments to SOLAS 74

NAUTICAL WATCHKEEPING NUTSHELL SERIES BOOK 7
PREFACE TO THE SECOND EDITION
Among all the books written by me so far, this one has been the most thought provoking. Much of the matter here is based on experiences and observations by myself and the officers who have been my students in this subject during the last twenty years.
Seamanship is a subject where changes occur frequently - different types of ships, differing nationalities, varying types of equipment, new legislation, increasing automation, clubbing of duties of personnel, reduction in manning scale, changes in traditional practices that were once considered sacrosanct, etc
In order to ensure that the material in this book is in line with current practices at sea, I did a four month voyage in command of a foreign-going bulk carrier just before publication of this book. After the Second and Third Officers had read the various chapters on anchor work, they had no problem going forward in charge of anchor stations. I can now confidently recommend that the Third Officer may be in charge of forward stations, on all ships, as suggested in this book.
In this second edition, watchkeeping on oil tankers at sea and in port have been included.

PRACTICAL NAVIGATION NUTSHELL SERIES BOOK 1
PREFACE TO THE FOURTH EDITION
The overwhelming response, in India and abroad, to the ‘Nutshell Series’ of books, especially this first one - Practical Navigation - has encouraged me to keep thinking of various ways by which improvements could be made with each subsequent edition.
In the third edition, sufficient theory was added to make the student understand the subject of Practical Navigation better than was possible with the previous editions.
The use of a simple, scientific, electronic calculator was illustrated and encouraged throughout, though working with the help of Nautical Tables was retained.
Since the subject of ‘Spherical Trigonometry’ has been adequately covered by ‘Nutshell Series’ book number eight, the descriptions of various steps in the chapters on Great Circle and Composite Circle Sailing have been suitably reduced.
During a voyage in command from India to Europe and back in mid 2003, I discovered that the combination of sun sights at noon was not being done efficiently by officers of today. What was routine in the mid sixties now seems to be an awkward procedure being done to mainly satisfy ISM requirements! Hence I decided to add Chapter 26, ‘Noon position by Sun’ to this book.
In this fourth edition, the only improvement made to the third edition is the addition of Chapter 26.

SHIPBORNE RADAR NUTSHELL SERIES BOOK 3
Every author who writes a technical book, does so with a certain purpose in mind, to suit a specific need. This book is intended not only to make an officer competent in the use of radar, but also to serve as a reference book that he would like to carry with him at sea.
I have tried to give radar plotting the importance it deserves by devoting nearly half the book to it. Work sheets, showing the working of each exercise, have been included so that quick revision is possible whenever desired.
In the second edition, minor changes have been made in parts I, II and III to keep uptodate especially in view of IMO’s Performance Standards for Navigational Radar for sets fitted after September 1984. No changes have been made in Part IV – radar plotting.
In the third edition, two new chapters have been added in Part I, namely ‘Developments in basic radar’ and ‘The raster scan display’.
A new part - Part V ‘ARPA’ - has been added. This has been intentionally included at the end after radar plotting, with a separate index, so that the student may study radar first without too much information coming to him prematurely.
Minor revisions have been made throughout to incorporate changes contained in IMO’s ‘Performance Standards for Navigational Radar’ for radar sets fitted after 1st January 1999.
My grateful thanks to my colleagues at the college for their valuable suggestions.
