Hello Submariners,
I made a 4 bearings technique helper!
Give your initial course, the time interval you will use and 3 bearings,
It will give you the course of the target.
Then give it your course and the distance travelled before the 4th bearing.
Enter the 4th bearing and it will give you the solution.
You can find it with more infos at :

And here's a geogebra construction, I made, to test the correctness of the tool :

Let me know what you think.
