The Rhumb Line Formulas. With the next diagram, we expand on the work above: The rhumb line AZ is divided into a large number of equal parts AB, BC, CD, DZ.
Key Words sailing formulas, dead reckoning, rhumb lines, loxodromes, ellipsoid Introduction The formulas for determining a ship’s dead-reckoned position, given an initial known location,...
Formulas regarding the rhumbline sailing computation are given in a form convenient for calculations done with a use of commonly accessible electronic calculators.
The rhumb line connecting any two points of the great circle on the same side of the equator is a chord of the curve. If the two points are on op-posite sides of the equator, the direction of curvature of the great circle relative to the rhumb line changes at the equa-tor. The rhumb line and great circle may intersect each
rhumb line between two places does not change its true course. A rhumb line makes the same angle with all meridians it crosses and appears as a straight line on a Mercator chart. For any other case, the difference between the rhumb line and the great circle connecting two points increases (1) as the latitude increases, (2) as the difference
27 cze 2024 · In this paper, equations are established to solve problems of Rhumb Line Sailing (RLS) on an oblate spheroid. Solutions are provided for both the inverse problem and the direct problem, thereby providing a complete solution to RLS.
Rhumb Line by Plotting. In one sense, the fundamental solution to RL sailings is just plot the two positions on a nautical chart and draw a straight line between them. After doing this, the course is easy to read relative to any meridian it crosses.
