Sailor Steve - read it again :hmm:
A quick edit might save your "Skipper of the month" nomination..
ahh heck let me make it easy for you - the example i drew there - - 3:15 minute rule plot.....
Quote:
ex. plot contacts with 3 minutes 15 sec. interval - the plot will show the speed of the target by measuring the range between plots and multiplying the kilometers with 10.
Example the target plots out to have 0.500 km's between plots - aka 5 knots.
