## Formulae for the MarinerThis 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 āspecial rulesā 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 matterif 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.) |

Great Value!

This is probably the single most helpful publication that I have found to assist Maritime Academy Cadets, (Deck) in preparing for their Coast Guard License Exams. I used it for all my exams from, Second Mate thru Master and later as a quick reference for teaching at a Maritime Academy.

I think there is an error in one of the API formulas, but it may be corrected in this edition, however this publication places most everything necessary for Deck Officers into a single convenient format at a very reasonable price.
