Over many centuries, wars have been lost due to lack of food and proper supplies for the troops. Without a way to survive, the troops had to retreat rather than stay and fight. The same need applied to ships at sea. "New York to Okinawa Sloooooowly" is the true story of a soldier who served on one of the supply ships that were vital to the survival of the troops in battle during Wolrd War II.John Barnes graduated from high school in 1941. While many of the kids in his class headed off to college, that was not John's plan. He wanted to join the marines, but when he discovered that his mother would not sign the papers, he set his sights on the US Coast Guard, the same service as his favorite cousin, Frank. After his basic training, he and his shipmates headed out on a journey that would ultimately take them to Okinawa. Through the severe storms, typhoons and enemy aircraft attacks, they got the job done come hell or high water.

This book is an updated and expanded edition of a text that has been used in navigation courses for 30 years. It covers practical small-craft navigation (sail, power, or paddle), starting from the basics and ending with all that is needed to navigate safely and efficiently on inland and coastal waters in all weather conditions. It is for beginners, starting from scratch, or for more seasoned mariners who wish to expand their skills. Topics include: Charts, Chart Reading, and Chart Plotting Instruments and Logbook Procedures Compass Use Piloting and Dead Reckoning Lights and Buoyage Tides and Currents Rules of the Road GPS and other Electronic Aids The GPS tells us where we are and how fast we are moving in what direction, but it can never tell us the safest, most efficient route to our destination. That fundamental task requires the basic navigation skills taught in this book, which we can use as well to check the GPS underway, and then be prepared to navigate without the GPS if we need to. The hallmark of good seamanship is to look ahead and be prepared. The text covers not only the long tested traditional methods of navigation but also the efficient use of the latest technology in electronic navigation and charting.

Formulas for the Air Navigation Computer is written for pilots and air navigators at all levels of experience from the novice to the professional. The book is self-help on how to use the E6-B Air Navigation Computer. An E6-B Air Navigation Computer is a circular slide rule with a wind slide on the reverse side. It is dedicated to performing all calculations related to pre-flight planning and in-flight air navigation. Every pilot has an E6-B Air Navigation Computer, which is supplied with a very brief instructional booklet when the E6-B is purchased. However, the booklet only covers a few basic formulas, and many more formulas are required for passing the pilot navigation exams at various levels and, of course, for all operational flying. Obtaining all these different formulas from various sources is time consuming, as this author has discovered over the years. They are not readily available in one book. This is the reason for writing Formulas for the Air Navigation Computer; it is a unique collection of air navigation computer formulas. The formulas are written as they appear when set up on the E6-B Air Navigation Computer. A full description on how to solve each formula is included, along with a worked example and also the methods for using the wind slide to calculate wind triangle and other navigational problems associated with the wind slide. The book is easy to follow by the novice pilot and a convenient reference source for the more experienced pilot. The book is complete with all the formulas a pilot of any level should need to know. It is laid out in a simple way with over 122 formulas and methods, covering Time, Speed & Distance, Air Speed, Altitude Navigation, VNAV, One-in-Sixty Rule, Wind triangle Calculations, Wind Finding methods, Fuel Calculations, Pressure Pattern Navigation and more.

The second edition of "Sea Clutter: Scattering, the K Distribution and Radar Performance" gives an authoritative account of our current understanding of radar sea clutter. Topics covered include the characteristics of radar sea clutter, modelling radar scattering by the ocean surface, statistical models of sea clutter, the simulation of clutter and other random processes, detection of small targets in sea clutter, imaging ocean surface features, radar detection performance calculations, CFAR detection, and the specification and measurement of radar performance. The calculation of the performance of practical radar systems is presented in sufficient detail for the reader to be able to tackle related problems with confidence. For this fully revised and updated second edition new material has been added on the Doppler characteristics of sea clutter and associated detection processing methods, bistatic sea clutter measurements; electromagnetic scattering theory of littoral sea clutter and bistatic sea clutter; the use of models for predicting radar performance, including discussion of Lognormal and Weibull models; further results and extended discussion on the modelling of the K distribution shape parameter for different conditions; the simulation of Doppler spectra of sea clutter; high grazing angle scattering; and the use of the K distribution in other fields. The material has been reorganized into four parts: Sea Clutter Properties, Mathematics of the K distribution, Radar Detection and Physical Modelling. This reorganization allows readers to access specific areas quickly, without the need for an extensive knowledge of the other parts.

First book to give an insight into a growing area of interest - stealth warship technology - which is crucial for future developments in warship construction. It demonstrates the importance of materials used in warship construction and how this influences all of a naval platform's design parameters.
Stealth technology is now considered a critical component within warship design, with interest in the concept of stealth increasing around the globe as naval forces adapt to new challenges. Many new developing nations are now implementing their first generation of stealth technology military hardware. This exciting book explores the full extent of threats to warships and thus the transformational change in naval architecture to incorporate these modern stealth technologies.
Discussing the history of stealth technology, with references to well-known aircraft, ships and events in military history, the book also provides readers with a unique opportunity to develop an understanding of the specialist skills required in this naval sector. This is an essential read for anyone interested in stealth design and the issues involved in this evolving technology.

This fresh categorisation and examination grew from the author's innate curiosity about the shapes and forms of the ships and boats of the Ancient World and particularly of the Ancient Egyptians. Many years sailing and the book by Nancy Jenkins, "The Boat beneath the Pyramid" which considered the vessel buried alongside the Great Pyramid of Giza sparked this curiosity, and from this start point, the focus of the research moved to the catalogue of model vessels in the Cairo Museum collection, published by Reisner, and the surviving hulls from Dahshur. These sources were augmented and supported by the work by Boreux. Finds such as the timbers from Lisht added valuable information. An interest in the greater variety of vessels to be known from the Old and Middle Kingdoms concentrated the researcher's attention upon the craft of these periods. Three fragmentary examples of hull forms, supposedly not known until the Old Kingdom, have been included, as the categorization system proposed in this research attempts to push back the previously accepted dates of some Egyptian hull shapes.

For all radar users, recreational and professional. Covers the use of radar for chart navigation, blind pilotage, and collision avoidance. This Workbook is designed to be used in classroom or online courses in radar, or for individual study outside of the classroom. The lesson structure follows that used by several schools in the US, based on the background reader Radar for Mariners by David Burch. The Appendix on advanced radar plotting is included for professional mariners who seek more practice on interpreting ARPA output by working out the vector solutions themselves. The ability to manually interpret the radar interactions seen on the screen, independent of electronic solutions, is in keeping with the fundamental tenet of good navigation and seamanship that we should not rely on any one aid alone.

"Astro-navigation from Square One to Ocean-master" is an impressively dynamic and understandable book. It is clear and concise with a large number of excellent diagrams that admirably compliment the text, demystifying and simplifying the art of astro-navigation. The excellent glossary of terms and language used, together with the highlighting of important points make this book particularly applicable to teachers, students and those new to the subject."Captain James P. Hughes. Lecturer in Nautical Science, South Tyneside College

Profusely illustrated throughout.

Sextants are used to measure angular heights of celestial bodies above the horizon to find the latitude and longitude of the observer. They can also be used on land with artificial horizons. Sextants can also be used to find the correct Universal Time by measuring the angular distance between the moon and another body along its path across the zodiac. In coastal waters or on land, sextants can be used for very accurate piloting by measuring the horizontal angles between charted landmarks. The vertical angle of a peak above its baseline determines the distance to it, which, combined with a compass bearing, yields a position fix from just one landmark. The angular dip of an object (island or vessel) below the visible horizon can also be used to determine the distance to it. This booklet explains how to get the best results from plastic sextants, and presents numerical comparisons with similar data from metal sextants. Sextant piloting techniques are also reviewed as they are an ideal use of a plastic sextant.

Celestial navigation is a way to find your latitude and longitude on earth using a sextant to measure the angular heights of celestial bodies above the horizon. It has been used by mariners at sea and explorers on land for three hundred years, and it is still used today as a dependable backup to modern electronic navigation. Routine celestial navigation relies upon accurate time (Universal Time) to find the longitude of a position (latitude does not require time). Advanced celestial navigators can find longitude without knowing the time using a technique called Lunar Distance. In this technique, the sextant is used to measure the angular (diagonal) distance between the moon and another celestial body. Since this distance slowly changes as the moon moves eastward though the stars, it can be used to find the time of day that is needed to complete the longitude determination.The process of finding longitude from lunar distance, however, requires special tables that have not been published in the Nautical Almanac or other sources since the early 1900s. Although software solutions have been available, most advanced celestial navigators are very grateful to navigation historian Bruce Stark for creating these printed tables dedicated to this task. They have been used and tested by mariners for more than 15 years and are praised by experts for their ingenuity and ease of use in solving this complex navigation exercise-which all agree is the hallmark of an expert celestial navigator.With The Stark Tables in your nav station, you no longer have to fear losing power to your electronic navigation aids, nor are you dependent on accurate time from any official broadcast.Besides their practical use in back up navigation, historians have used these tables for years to interpret the logbooks of Lewis and Clark, David Thompson, James Cook, Matthew Flinders, George Vancouver, Nathaniel Bowditch, and other notable explorers and sea captains."It is remarkable in this day when the very survival of celestial navigation seems in question, that an individual should suddenly appear on the scene and present to the world such a brilliant piece of work. Stark has rendered a great service to the celestial navigation community." - Robert Eno, The Navigator's Newsletter"Captain Cook would have relished using these tables, had they been available to him then."- George Huxtable, FRIN

A soup-to-nuts introduction to small, economical sailing craft

Trailer sailers--the smallest, most economical sailboats with sleeping accommodations--are a popular platform for learning the basics of sailing and are often considered to be the entry level to cruising under sail. Author Brian Gilbert shows how trailer sailers can be the ideal craft for a lifetime of enjoyment, including serious, long-distance cruising. This book covers all the bases, including how to inspect, buy, and equip a boat; how to trailer, sail, navigate, and cruise in small boats; how to use communications and navigation equipment; and more.

This book contains the definitive analysis of the navigation and achievement of the discovery of the North Pole by Robert Peary and Matthew Hensen in April of 1909. The report is the work of members of the Foundation for the Promotion of the Art of Navigation. It was commissioned by the National Geographic Society in 1989 to resolve the controversies surrounding this achievement once and for all. "I consider this the end of a historic controversy and the confirmation of due justice to a great explorer." - Gilbert M. Grosvenor, President National Geographic Society

"Navigation puzzles, controversies, historical problems, and other ponderables demystified by an expert navigator and writer. Joe Portney is a US Naval Academy graduate and Air Force navigator who has participated in three historic flights over the North Pole. He is a past President of the Institute of Navigation and recipient of the Weems Award for continuing contributions to the art and science of navigation. He has produced a wonderful little book here, chock filled with interesting tidbits, each of which can be read in a few minutes but will stimulate your thought for many days to come. Some are very basic, others more involved, but he provides a clear explanation of each. Some refer to math computations that we might not all be familiar with, but this is not a distraction from the main points being made even in these few cases."

Britain's foremost scholar of the international shipping industry, based at the Centre for Port and Maritime History, University of Liverpool, here examines the growth and development of Japan's modern shipping and shipbuilding industries across a wide range of topics, through the pre-war, Pacific War and post-war periods, to the transfer of shipping technology, the role of bulk carriers and world trade and the organization and structure of the Japanese merchant navy. Prompted originally by his research into the decline of the British industries in a global context, his focus inevitably turned to Japan which in the post-war years had replaced Britain as the world's largest ship operators and ship owners and remains so today.
