Nav Tool for Reading Minutes on Nav Map

[kevinsue]

Would anyone know if there is a tool similar to this one in the screenshot, found in the user maps, somewhere available for download, except graduated for individual minutes instead of tens of minutes? Would make plotting contact reports etc more precise if one was available somewhere. One that scaled with the map would be even better!

u can always use maneuvering board for that and that chart from your screen is made for RN not for plotting contact reports

Thanks for the reply I've never been able to work out what that Timepiece Board actually does. I heard a whisper on the wind that a full Celestial Navigation mod may be in progress so I thought I had better start brushing up on Coastal and Celestial navigation just in case, and intend to make a start with Sjizzles nav tutorials if I can find them again. Years ago I did a Celestial Navigation course at a Tech college and learned the "Marcq St Hilaire method" otherwise known as the "Intercept Method" but after not using it for three and a half decades, the knowledge has gradually faded into oblivion!

Wow! logarithm and haversine tables...haven't heard of or seen these in over half a lifetime....

Any talented person able to do this will add an invaluable tool for plotting radio contact positions accurately instead of "near enough is good enough". Using radio contacts and predicting future positions of convoys is by far the best method of finding and intercepting targets in the vast expanse of the Atlantic.
