FORMULAE FOR THE MARINER

According to the author, the present volume was written with the ultimate intention to provide merchant seafarers as well as the other mariners with the formulae they may need during their work. Unfortunately, most of those formulae tend to get forgotten by the people if not used every day. It should not be looked at as the complete list of all formulae to solve all possible problems, but rather to give the list of commonly applied ones.

One of the great features of the publication is the coverage of the different areas, from navigation calculations to the ship stability electricity related calculations and so many others. After the introductory part, the volume gives the general information about the key functions of the calculator machines, and trigonometrical functions. The navigation related calculations include rectangular to polar conversion, ETA, Mercator sailing, great circle, amplitude, azimuth, altitude, and others.

Then, there are many practical calculations covered including, but not limited to the visibility of the navigation lights, fuel conservation, draft change caused by the density, volume and area, bearing problems, cargo handling etc. Several conversion tables conclude the volume.
