IMHO for now, there are simply dozens of far more worthy tasks for the devs to crack on with...? |

I wasn't suggesting we do have sextants, but the opposite, ie it's a waste of time.

I don't think a sextant would help in that regard as the intrinsic error of the instrument is likely much more than any navigational error caused by "manoeuvring" would be, unless such manoeuvring went on for days..

the accuracy of the sextant is limited to the determination of latitude and longitude ?

A competent navigator under good conditions using a sextant can get a fix with 5 to 10 nautical mile accuracy

It’s certainly not precise like GPS of course, but remember that five nautical miles is just under 10 km, well within visual range at sea to find an island or whatever. Celestial navigation is fascinating stuff, and it’s surprising how accurate it is.
We have our people simulating it in our campaign for Wolfpack, outside of the game, but when they go on patrol I give them their celestial data and they plot fixes using real world data.

The sextant can only calculate latitude' but needs to be used in conjunction with a very accurate chronometer to determine longitude. A sextant without one is as much use a bath-plug on a submarine.

Yes indeed! You are then forced to do as the old old timers did and “sail the latitudes”. Sail straight north or south to the latitude of your destination, then east/west till you get there, taking a noon sight for latitude or polaris sight each day.

Interestingly enough there is code currently in the code for a sextant of some sort. Let’s keep our fingers crossed!

This would go way over the heads of 99% of the players. Which already have trouble with the TDC or submerged dead reckoning. So would be left unused by the majority. Asking the devs to implement celestial nav in the game is asking them to waste time where they could be doing other stuff. Asking the devs to disable the update of the uboat icon position is the easiest for them to do. Maybe only leave the starting position as a reference. Then it is the total responsibility of the crew to keep track of their movement in a log as they go away of the reference point. Because, if you enter the game in total overcast then you will be completely lost without any way to fix your position in that session. If you do not have the convoy or other objectives in hydrophone-, or later radio direction finder-range, then you might as well give up. If the devs find time to implement this fully down the line then I'm all for it.
