Interesting. You lost me a little bit here, how do I go about doing this? Pardon me for being such a noob.


Hehe..as per the diagram below, starting at point A, if you travel for 2 hours on a heading of 120° at 4 knots then after an elapsed time of 2 hours, you will be 8 nautical miles from point A at the new position point B in the direction of 120°T from your point of origin. In SH5, you use the Speed Conversion Charts to find out how many meters/Kilometers you will travel when maintaining a speed of X knots for X amount of time. Just use the ruler to measure the calculated distance in the direction of the boats magnetic heading to get point B.
