One side says the VMG is better tacking along the rhumb line than banging the corners and you risk overstanding the mark on a longer layline. The other side says the VMG's average out to be the same but the extra tacks along the rhumb line slow the boat down too much.
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:
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...
In broad terms, there are two main types of sailing, namely, the Rhumb Line sailing and the Great Circle sailing. The Mercator Sailing is the most accurate method employed in marine navigation to handle calculations related to Rhumb Line sailing.
Namely, to reach the Great Circle vertex with two rhumb line legs ensuing the optimized distance, an initial rhumb line course equal to the orthodromic course at middle latitude may be used.
Offshore racing sailors will always find the fastest route. That is, after all, the whole point of the exercise. Often that means sailing the rhumb line, i.e., the shortest, most direct course between the start and finish. Sometimes, though, they’ll also take “fliers,” sailing a ...read more.
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....
