Peer Reviewed

Abstract:	Sailings may be divided into two general classifications: a. Plane Sailing b. Great Circle Sailing The first of these considers the earth as a plane (flat) projection. The second, great circle sailing, considers the earth as a sphere, hence employs true values. The basic problem of the sailings may be stated simply: Determining course and distance between two places of known latitude and longitude. Plane sailing may be subdivided as follows: 1. Parallel sailing 2. Traverse sailing 3. Mercator sailing We shall consider the plane sailings first, in the order aforementioned.
