A rhumb line makes the same angle with all meridians it crosses and appears as a straight line on a Mercator chart. The principal advantage of a rhumb line is that it maintains
Miljenko Petrović. Stonska 1A, 10020 Zagreb, Croatia. ABSTRACT. This work tackles the problem of misconception when using sophisticated mathematical tools, nonlinear optimization in this particular case, to solve a navigational problem.
Short distance sailing is a term which is applied to sailing along a rhumb-line for distances less than 600 nautical miles. From the formulas derived above, the following are used extensively in short distance sailing:
The rhumb line connecting any two points of the great circle on the same side of the equator is a chord of the curve. Along any intersecting meridian the great circle crosses at
The formulas for determining a ship’s dead-reckoned position, given an initial known location, the vessel’s course and speed, and the time elapsed, are referred to as the sailing formulas....
1 cze 1995 · This paper provides simple formulas that include the earth's oblateness, which can be readily applied to sailing calculations. The accuracy of these formulas is assessed, and they are shown to be good to about 10 m over ranges up to 1000 km.
There are two general types of sailings: great-circle (GC) sailing, which yields the shortest distance between two points, and rhumb-line (RL) sailing, which yields a straight line on a Mercator chart (Section 11.4), the common map projection used on nautical charts. We cover GC sailing in Section 11.22. Commercial ships at higher latitudes often
