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 gist of this essay is a novel concept showing an intrinsic property i.e. orthodrome-loxodrome correlation using a well-known formula. Keywords: marine navigation, middle latitude, middle longitude, orthodrome, loxodrome. INTRODUCTION. The loxodrome is a transcendental curve spiralling between the North Pole and the South Pole.
Using two different examples, this video shows how to calculate the course and distance between two positions; and how to calculate the position arrived if d...
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
2. Loxodrome Equation A vessel maintaining constant heading moves along loxodrome (rhumb line) which is a line cutting all the meridians at the same angle. The Earth’s meridians are not parallel to each other, thus the line crossing them at the same angle is not a straight
ABSTRACT Although the mathematical basis for rhumb lines on the ellipsoidal earth is well known, the earth's oblateness is usually neglected in dead-reckoning sailing calculations. This leads to si...
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.
