Since the time of the initial publication of this title nearly thirty years ago, the marine navigation has undergone numerous significant changes, and this edition of the book has been revised in a thorough way in order to meet all expectations of the readers as well as the requirements of the maritime industry.
Some of the changes were dictated by the climate change effects on the weather, on the basis of the data collected in the course of the meteorological observations from satellite stations. The sailors working all around the world have found this volume very useful and practical; it may be treated as a go-to book for all offshore sailing expeditions as the content of the volume includes the information covering the shipping routes, safety at sea, weather and seasons, currents - in fact, everything they need to know to make their voyages safe.
The publication has been deservedly considered a must-have one on board every vessel planning any long-distance sailing. It stands alone as the real icon of ship routing information for the cruisers. The author offers different choices of the routes including valuable waypoints specifying the latitude/longitude.
It is a good roadmap to the oceans and seas of the world, providing extensive data on the various shipping routes supplemented with the advisable landfalls plus marinas, i.e. it is an excellent practical reference for sailors.
The original intention of the compilers of the present pamphlet was to provide readers with the enough practical knowledge they would require to observe and plot the celestial position lines in a correct ways, and also to be able to obtain any technical information commonly needed for completion of the celestial navigation day. In fact, the degree of proficiency that can be reached in the field of celestial navigation, depends on the practical experience of the mariners.
However, the present volume provides readers with lots of useful information that can be related as a foundation on which the whole other knowledge shall be built, and using this information, the mariners will be able to make the celestial navigation a much more satisfying experience. Please note that the information n an data provided in this title shall be used for training purposes only. For many centuries, the mariners used the small and big dippers as a sort of guides as they always stayed in a same position.
The star that did never seem to move at the sky was noticed to have a constant attitude and the mariners of the past used this to move north and south. We would not consider celestial navigation a dead art at all, even in the age of modern equipment and electronics. It is actually used to update the systems of electronic navigation and also used when there are ni any other means readily available...
Another non-resident NAVEDTRA Quartermaster course. The main content is starting with the introduction to navigation providing the enrolled trainees with the required fundamental info directly related to the basic navigation. As quartermasters, seamen are commonly engaged in many various aspects of marine navigation. Subject discipline is looked at as both art and science; it actually means that basic knowledge of math will be considered a must to suffice the navigator's needs, because in the real life there can be no feeling that can ever be compared to knowing in case you form a part of the team responsible for the safe navigation of your vessel.
The training material contained in this part of the training volume will enable all trainees to describe the TCS, standing for the "terrestrial coordinate system", dead reckoned track, correctly interpret the symbology of the navigation charts and be able to determine their accuracy, plot the directions and positions, measure the distances, properly describe the CCS, i.e. "chart correction system" and get the nautical charts corrected using information contained in the Notices to Mariners plus, of course, order the charts, label them and stow as per established procedures. References and glossary are there at the end.
Originally, the present training course was published nearly twenty years ago with the main declared intention of its authors to develop a good training resource to be practically helpful for the sailors and would significantly improve their professional and military technical knowledge; subject course was supposed to be used when preparing to sit for the Navywide examinations.
The content includes various information covering the everyday occupational knowledge and the skill requirements, the text and informative data tables supplemented with the numerous illustrations included to assist trainees with getting better understand all provided information. There is another important and practical feature of this title, i.e. the references to the useful relevant info and data that may be found in other books.
The materials in the volume have been arranged in the eighteen chapters that provide the general information, describing the steam turbines, reduction gear together with the associated equipment, pumping arrangements, lubrication and air ejectors, heat exchangers, various engineering operations and their administration, refrigeration, piping and systems, air conditioning, compressed air systems, steam operated plants, auxiliary equipment, auto-boiler controls, propulsion boilers, their fittings and tools, etc. The glossary of terminology has also been provided.
This title is mainly intended to serve as a practical guidance to measures to be taken in order to evade the Tropical Revolving Storms and how to "ride out" with the minimum possible damage in case you have found yourself in the centre or near such storm. This book by P. Vergroesen is intended to provide mariners with all required information.
All navigators shall know which exactly information they require; however, it appears to be quite time consuming and also difficult to compile all relevant technical information and draw correct conclusions. Trying to make this a bit easier, the author of the present booklet has brought all of the information and regular cyclone tracks in one monthly chart for all areas.
The mariners can determine both storm track and speed using the results obtained during the consecutive observations. The first part of the book provides general information and addresses preparations to be made in advance, while the second is dedicated to the cyclonic areas, making closer examination of the strategic courses, weather reports and safety matters in different marine harbors.
The remaining parts of the booklet deal with detecting/plotting of the tropical cyclones, illustrated divergents, cyclone navigation, defining the distance to and direction of the center, plus provides advice on what shall be done at ports when cyclone is passing.
This work was prepared by Edward Lewandowski, and it provides the players fo the marine industry with probably the best theoretical treatment of the marine craft dynamics. The materials directly concerned with this matter have all been rendered approachable. The author has presented a good professional treatments of the forces/moments acting on the marine crafts, aiming to give readers the necessary instruments to conduct proper prediction of the marine craft motions both in calm water condition and in waves.
In addition to the development of the relevant equations, he has also provided the existing relations permitting a minimum approximate evaluations of the associated coefficients to obtain the useful results. Such approach is starting with the motion equations being applied to the rigid bodies, relative to both fixed- and moving coordinate systems, followed by the examination of the hydrodynamic forces, hydrostatics and then progressing to the forces acting on the moving craft in various sea conditions.
The author has also included several practical examples including hydrostatic calculations, directional stability, and also the wave-induced motions plus useful discussions on fin-hull interactions and heavy torpedoes, dynamics of the HSC and numerical stability etc.
Sailing is considered a very complex and technique- and gear-intensive sport. The present publication was intentionally released to provide all interested people with twenty-two fundamental principles making the core of the sailing-related knowledge; due understanding of the principles explained in the book will help readers attain a genuine mastery.
The volume is mainly aimed at intermediate-level sailors, so-called "practiced novices"; we would not say that it is a best choice for the absolute beginners as the lessons and tips included by the author will only be of use for the people who are already possessing some basics of sailing. But for the intended audience, it is really a treasure, an excellent source of relevant information. It will provide sailors with valuable practical advice on storm sailing, performance tuning, offshore boat cruising, advance sail trim and many other interesting and practically important topics. For people having some basic understanding of sailing, this publication will be a great "next step".
The book will be of great interest for people willing to improve their understanding of the sailing concepts and protect themselves in difficult situations at sea. The content is really outstanding and it has been already met well by the readers in many countries. The author has provided lots of valuable details about the mechanics of sailing etc.
All information and advice provided in the pages of the present Guidance has been purely intended to serve as a sort of practical guidance. Nowadays, huge oil and gas reserves are there under development offshore Russian Arctic, and vast quantities of the developed oil and gas are then transported by means of the vessels from Baltic Sea and Russian Arctic areas.
Of course, the transportation of the oil and gas by sea going on year-round places very serious challenges on the vessels and crews. Some additional demands are imposed on the crew members and ship systems by the operating in cold conditions, and such demands would typically include the communications and navigation matters, lifesaving, shipboard main propulsion and auxiliary machinery, etc. The present Guidance has been specifically developed for the operators of the vessels operating in cold climates and particularly those commonly exposed to the sub-zero temperatures on a regular basis.
The main aim of the compilers of this work was to provide the shipping industry with the useful information to make all people involved better understand the hazards associated with operating in such conditions and also to facilitate the implementation of required practice and establish the procedures to meet the recognized standards of safety as well as prevention of pollution of the surrounding environment.
