MoBo (with maps), free
Chart Navigator Pro (with maps)


0.0000000007715 % is the probability that your 4 bearings drawing on your map is exact that what has happened on the sea.
10% probability for ONE bearing that the soundman is error-free with his shouting.
1.6% probability for ONE arc-drawing that the arc is error-free with your SH5-arc-drawing tools.
After 4 bearings and 4 arc-drawings you got a 0.0000000007715 % that everything is error-free.
