An excellent source of reference for the prudent mariners providing them with the significantly improvised and no-instrument methods. The content has been found to be useful, fun to read, interesting and informative, helping readers to get the proper clear understanding of the general principles of navigation not addressed earlier. The text of the publication is thorough, well-thought and authoritative, making it a very definitive professional work for the seamen of all experience levels.
The seamen know that any instrument can fail, get broken or fall overboard. The present title by David Burch is aimed to show the seafarers how to find a way regardless of the navigational equipment possessed, and regardless of what boat or vessel they operate. The author has made a great job in explaining readers the making use of literally all available means and materials and apply them to the calculation of the speed and direction of the vessel, longitude and latitude and also to deal with all important aspects of dead reckoning and piloting of the vessel.
They will learn about the steering of the ship by sun, wind, swells and stars, finding the sun in the fogbanks, improvise their knotmeters and sextants, estimate the leeway, current and latitude, and a wealth of other vital information.
Very useful technical publication explaining all complexities associated with the atmosphere and intented to provide all info required by the professional seafarers to aspire them all to the first-class COC, i.e. certificates of competency. The content starts with the general information related to the meteorology covering the structure, density, temperature, composition and pressure of the atmosphere.
The following chapter is covering atmospheric pressure including isobars and barometers, barographs and pressure tendency etc, while the third one addresses the temperature, touching the temperature observation, energy transfer, radiation and other aspects. The next chapter is dedicated to water contained in the atmosphere covering its states, water vapor, evaporation/condensation, hygrometers and Dew-point, plus relative humidity.
The diurnal variations of the atmospheric pressure, temperature and atmospheric water are also dealt with. The remaining chapters of the volume are focusing on the clouds, providing clear description of their types and rate of the adiabatic lapse, for and precipitation, including visibility, haze and development, winds, including both land and sea breezes and anabatic/katabatic winds, temperate/polar zone circulation including anticyclones, cols and frontal and secondary depressions, subtropical and tropical circulation, proper organization and operation of the meteorological services, and available forecasting sources.
This excellent and informative guide will provide readers with the valuable storm handling tips. The storm handling is one of the hottest and most debated topics in the field of the seamanship; some seafarers prefer heaving-to while others usually choose running off.
The author of the volume is a professional and prominent sailor who sailed around the globe twice, single-handed, logging in total more than twenty hundred thousand nautical miles under sail. The approach used by the author makes the text very readable and descriptions very clear even to the newcomers. Note that the content may equally apply to the monohull and multihull vessels.
The book is offering remarkably comprehensive coverage of the subject and has been prepared in a simple and no-nonsense manner with huge amount of supplemental practical information and real life examples for better understanding. Moreover, the author is writing with striking clarity and precision, and his humor makes the book not only interesting but even fascinating, providing both novices and experienced seafarers with the realistic advice worked out on the basis of the author's own experience and analysis of the other's experience.
The content of the volume will help readers to increase their theoretical skills and choose the proper safety equipment for their boats, plus will enable them to boost their confidence in handling the boats in adverse weather conditions.
David Steel, the author of this perfect, very useful and informative two-volume set, was deservedly considered to be among the world recognized and respected naval publishers who worked in the past, namely in the late XVIII/early XIX centuries. His interesting and well-though publications were focusing on the naval strategy and established ship construction techniques.
The present work by Steel was originally released nearly forty years ago and was treated as the very first English manual providing all interested readers including students and specialists, with the best naval practice. The content of this set was specifically designed and worked out to aspire the young officers. The success of these books resulted in establishing the brilliant reputation of David Steel as a publisher. These publications provide all readers with the good descriptions of both practical and theoretical aspects of the masts/rigging, sails and the whole science of sailing.
The author perfectly combined the practical advice which is supported by both scientific and math explanations with the numerous helpful illustrations providing valuable insight into the British seamanship of the times of the Napoleonic wars. We would recommend these volumes to all persons with the deep interest in naval sciences.
Though the electronic systems of marine navigation are commonly considered extremely reliable, it shall always be taken into account that, should they fail while the vessel is at sea, their repair on board will most probably be not possible at all. In addition, they require constant supply of electricity. What if it fails as well, leaving the vessel with no means of finding the position and chart plotting?
Having no means of route planning, how will modern navigators continue their voyage in a safe manner? The present publication has been written in a very reader-friendly manner, providing interested readers, and in the first turn navigators, with a clear and practical yet quite simple to understand description of the navigation techniques which can be utilized in case the electronic navigation systems installed on their yachts fail.
The book will demonstrate how to understand the core principles standing behind the techniques they are using, see those techniques explained with no complicated math required, employ these techniques and put them into practice, i.e. use every opportunity to make the passage safe and seamanlike. The content is pretty well-illustrated presenting a variety of classic marine navigational methods the sailors can use and showing how some simple devices can be made by the voyagers.
The pilots are considered the critically important resources possessed by the marine navigators in the harbor approaches - they are professional ship handlers with a truly encyclopedic theoretical and practical knowledge of the local ports and harbor areas. Their presence is in many cases officially required by the local law or regulations.
However, they are not formally treated as members of the bridge team; however, again, it shall be understood that they are extremely important specialists. In most cases they remain the advisors to the ship master, who, in turn, are retaining the full responsibility for the safety of the vessel. Note that they have been given full navigational responsibility in Panama Canal and Suez Canal. Pilots are professional navigators and deserve respect and require management. Maintaining the due balance of the above mentioned elements is Captain's responsibility, managing the MPX, standing for the master-pilot exchange.
The main objective of the subject exchange is to inform the pilot about the main dimensions of the vessel, condition of the shipboard machinery and navigational equipment, and provide the pilot with all other relevant information that may be important for the safe planning. This publication will provide the readers with some basic aspects of navigating the vessel with a pilot...
The content of this monograph starts with the chapter dedicated to the ship control and dealing with the relevant equipment including the adaptive control systems on container ships, together with the technical concepts related to the control of vessels. The second chapter focuses on the problems directly relating to the decision supporting systems such as NAVDEC, materials on the technical development of the support systems and trial tests, decisions related to the safety of the shipping traffic in different sea situations, handling of the vessels in windy conditions etc.
Third chapter deals with the marine traffic and here the readers will find all required information related to the development and evaluation of the routing measurements, expert indication, analysis of the traffic incidents. Fourth chapter of the volume covers the SAR, i.e. Search and Rescue problems, including SAR of migrants, design of the lifesaving appliances based on the ergonomics, radar signals, risk analysis and regional exercises concerned with the oil spill preparedness.
The next chapter is dedicated to the meteorological aspects and weather conditions including numerical weather prediction, analysis of the associated criteria, global warming etc. This one is followed by the chapters relating to the navigation systems, air navigation and maritime communications, algorithms and methods...
Nearly every person who sails a lot possesses a very clear image in mind of the cold and warm fronts and lows and highs and roughly what to expect as they arch majestically across the daily weather maps in newspapers and the TV-screen. It all seems quite easy to understand and forecasts are at least somewhat more often than not, correct. But it's the times that forecasts are not correct which most concern us when we're at sea.
There are so many variables which all together must be accounted for in order to arrive at an accurate weather forecast that we may as well forget about reaching that ideal in our lifetimes. One scientist pointed out years ago that a butterfly flapping its wings over a parking lot on a hot day in Dallas may be the cause of a thunderstorm in Boston three days later. It was meteorologists who led the way to the new science named, appropriately, CHAOS...
This publication provides readers with a complete guide to the marine weather analytics plus tactics and avoidance of storms; the authors of this volume, Linda and Steve Dashew, are teaching the traditional forecasting techniques that are basing on the current observed weather conditions, together with the latest instruments including internet. Their efforts has resulted in an excellent tool for the sailors and power boaters, and in fact anyone with an interest in weather.
