Exploration with a Computer on Rhumb-line Sailing

Abstract

The navigator is frequently faced with the task of finding the course and distance along a rhumb-line between two places on the Earth's surface.The following paragraphs tell of a two-part investigation into the methods of calculating rhumb-line courses and distances.Part I deals with a comparison of the methods used and the results are presented in graphic form.Part II considers the various corrections that may be applied to mean latitude sailing to get better results.
