We now have two Sumner linee, A'and B', under Case I, whose common latitude is 25 19MS., and whose longitudes on the common parallel are 114 61K.7 and 115 31'.5. Hence, the difference of longitude on the common parallel is 115 31'.5 W. 114 59'.7 W. CHAPTER XVI. THE PEAOTIOE 01 NAVIGATION AT SEA. 381. Having set forth in previous chapters the methods of working dead reckoning and of solving problems to find the latitude, longitude, chronometer correction, and azimuth from astronomical observations, it will be the aim of the present chapter to describe the conditions which govern the choice and employment of the various problems, together with certain considerations by which the navigator may be guided in his practical work at sea. 382. Departure And Dead Reckoning.--On beginning a voyage, a good departure must, be taken while landmarks are still in view and favorably located for the purpose; this becomes the origin of the dead reckoning, which, with frequent new departures from positions by observation, is kept up to the completion of the voyage, thus enabling the mariner to know, with a fair degree of accuracy, the position of his vessel at any instant. At the moment of taking the departure, the reading of the patent log (which should have been put over at least long enough previously to be regularly running) must be recorded, and thereafter at the time of taking each sight and at every other time when a position is required for any purpose, the log reading must also be noted. It is likewise well to read the log each hour; for general information as to the speed of the vessel as well as to observe that it is in proper running order and that the rotator has not been fouled ...

Formulae for the Mariner
Author: Richard M. Plant
Publisher: Cornell Maritime Press/Tidewater Publishers
This book is a compilation of all the formulae that a mariner is commonly called upon to use but the exact workings of which he has perhaps forgotten. For each subject category, the author states the basic parameters in narrative form, often including a figure, graph, chart, diagram, or table, and then provides accompanying equations and their amplifications. Although some formulae that are simpler in format are propounded in other texts, many of those formulae lead to confusion in that a oespecial rulesa must be applied to them in order to obtain a correct answer. However, the rules applied to the formulae in this book work for all problems. In a great circle sailing situation, for example, the fact of whether the vertex is ahead of you or behind you does not matter--if you apply the rule(s) given in this book, you will get the correct answer. Another important feature of the book is its devotion of over ten pages of material to the international system of units (S.I.)

This guide is intended for professional mariners and for those studying for the US Coast Guard license examinations. The result of the author's experience teaching these subjects for many years, it addresses every major navigation problem with a short, accurate description, definitions of terms, and worked out examples. To help the reader the author has implemented real handouts from his classes, intended for students, as references, including worksheets for celestial and tide calculations. Vital information of all types is provided here, including a crash course in celestial and terrestrial navigation, magnetic deviation tables for calculating compass error, formulas for determining leeway, and tips for navigating close to home and across the oceans. Professor Palmiotti's expertise, earned through his vast experience as mate and captain, is now available, here, in compact form, for both veteran seamen and officers in training.
The Sight Reduction Tables for Marine Navigation (Pub 229) is published in six volumes, each of which contains two-eight degree zones of latitude with a one-degree overlap between volumes. They are designed to facilitate the practice of celestial navigation at sea. The tables are primarily used with the intercept method of sight reduction by entering arguments of latitude, declination, and local hour angle and obtaining tabulated altitudes and azimuth angles. The tables are prepared and published by NIMA on an as-needed basis.
On a merchant ship it is the watch officer who feels the full weight of responsibility for the safety of the vessel. This book not only helps a new watch officer shoulder that responsibility, but reinforces the knowledge and skills of the experienced mate. The complete scope of watchstanding duties, the use of modern bridge equipment, voyage planning, shiphandling, and shipboard emergencies are all addressed. The new edition is updated to reflect the changes in the industry and now features real-life case studies.

Chemical Data Guide for Bulk Shipment by Water: Marine Technical and Hazardous Materials Division. The data in this guide was compiled from a number of sources in the interest of safe water movement of bulk chemicals. Hopefully, by providing key chemical information in an easy to use form, this guide can help prevent or at least minimize the harmful effects of chemical accidents on the waterways.
World Voyage Planner
Author: Jimmy Cornell
Publisher: A&C Black
Jimmy Cornell is the undisputed authority on long distance voyaging. In his new book, he helps the would-be voyager plan their trip step by step. Aimed at those seriously contemplating an extended cruise (and those dreaming about the possibility), this book will give an idea of what is involved in developing the right strategy. Amongst many other aspects, Jimmy looks at: - World weather systems - Strategies for sailing long or short circuits in the Atlantic, Pacific and Indian Oceans - The pros and cons of different routes at different times of year (taking in account weather, timings, wind directions and strengths, likelihood of fog, icebergs, gales, etc) - The pros and cons, attractions and dangers of different routes (such as the problem of piracy) - Practicalities (repair facilities, common gear breakage on extended voyages, places to leave the boat to fly home if necessary, health considerations, provisioning for a long trip, personal safety measures, and much more) - Jimmy's top ten list of common things that ruin a voyage Written from an international point of view, Jimmy Cornell's Blue Water Voyage Planning can help sailors from any country going to any other achieve a safe and enjoyable cruise.
According to author Captain Henry H. Hooyer, forces acting on the ship have an effective lever arm with respect to a hypothetical pivot point. The forces creating or affecting this pivot point include the ships motion, underwater resistance, and momentum. The book will be particularly helpful to pilots and ships officers, and those whose jobs require a thorough understanding of ship behavior.

'Inspiring leadership lessons from the sea,? Rear Admiral Robert O. Wray Jr, USN (ret), author of Saltwater LeadershipAlthough merchant ships carry 90% of the world's trade, the mariners who run them have little guidance on leadership. This can result in disasters such as the Titanic, Costa Concordia, the Exxon Valdez, and the recent El Faro. With modern ships being worth several million dollars, seafarers need leadership advice at every level of their career. Golden Stripes, Leadership on the High Seas provides this guidance, and much more. Captain Parani weaves together his rich experience, cutting-edge insights and real-life stories in this book which has already garnered international acclaim. The reader will discover how to run a tight ship; enhance expertise; lead and communicate with a team; implement safety leadership; decide effectively in high-stake situations and be inspired by legendary sailors. It is a practical leadership action plan which can be applied at sea, or in any other workplace, anywhere.Golden Stripes is the first leadership book of its kind, written by a mariner specifically for commercial shipping. The author's experience both on board and from his corporate roles gives him a unique perspective on why, when and how sailors fail or succeed. Important messages are woven around engaging stories, quotes and practical leadership models, making this an indispensable read for all leaders.
Data in this book are no longer valid for navigation. It is preserved in print because many training programs (including USCG and US Navy ) use examples from 1981 to teach celestial navigation. USCG license exams require data from this almanac. These exams also require Sight Reduction Tables, Pub 229, Vol. 2 and a 2102-D Star Finder.
