Anybody know of a good port to port distance calculator ? I need to know how far by sea it is from Plymouth to Bridport ? Any idea of rough time on average of 20 knots ?
I use Google Earth, click on the little ruler at the top of the screen, then click on path, change the units of measure to nautical miles, and then start clicking your trail from your departure point and it gives you a running total of the distances
This one is good when You get use to it. Made for professional shipping but free access between 19:00-00:00 GMT. It calculates mainly on deep draft fairways so with boats You might have s slightly shorter sailing.
