Gentlemen,
maybe something of an interest for you. I kinda wrote a formula which maybe useful. MAybe;> It can be used to get a running fix from bow and beam relative bearings. It is well-known procedure. But to speed up calculations, there are so-called method of double angles and 0.7, and also distance travels equalls distance off. Plus a few so-called special angles , like 36 deg bearing1 and 69 deg. bearing 2. In the last, particular case distance travelled is equal distance oiff the beam to the object you are taking bearing on.
Anyway, instead of using just a few angles why not to use any angle at the first bearing and calculate what angle should be at the second bearing if you want to have distance travelled between bearings to be equal to distance offf beam of that specific object you took bearings at.
a very simple drrawing is following.( see attachment).
Again, nothin revolutionary, just maybe helpful. Thank you
