Exploration with a Computer on Rhumb-line Sailing

B. J. Moss

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.
