Plot DR track from Logbook with Leeway IN05-0007
Published at : 18 Jan 2021
We use OpenCPN to illustrate how to plot a DR track accounting for leeway.
Note this is a pure graphic exercise when done this way. The video shows how you would plot this on a paper chart. If you were actually using OpenCPN for navigation, then you would have this track plotted out automatically as the trail of your past positions.
In your actual navigation, even if you are using an echart program like OpenCPn or one of countless others, then it is still good practice to have a paper chart out on the chart table onto which you periodically plot your position and label it with the time. This remains Rule No. 1 in navigation.
