It is easy to save a single place using a pin in Goggle maps (for example a parked car).
The accuracy can be type 1 foot.
Assume one store 2 pins for example Boie 1 and 6.
All courses are identical the same so the coordinates could then be easy calculated relative to boie 1 and 6.
Is there any easy way (app, tool) to import the total course positions and just relate/connect them to boie 1 and 6?
One can then navigate to all boies from the boat.
For us it would be much easier find the sunken boies next time.
Maybe there already is a solution for this but I have not found anything?
Any suggestions, ideas?
