Manual Aiming of Torps

[Balimaar the Bass Fish]

So I am finally getting into working out torpedo solutions manually and am enjoying the challenge. I am noticing, however, that a number of my torps are missing by zooming past my target's stern.

This could result from any number of ways from my method so I'll post what I do here and hopefully someone can point out where the issue might be.

==FIND SPEED==
I do this one of two ways, it depends on if I have time for a solution I feel is more accurate.

(1) Do it the old "chronometer timing how long it takes for the ship to travel bow to stern"

This one I do if I have time:

(2) Place a marker on the map and start the chronometer. Run it for 3min 15 sec. Stop the chronometer and draw a line connecting the two markers. Divide by 100.23 gives the speed in knots.

==FIND COURSE==

I really dont trust the guesstimation involved in using the tool, so I use the map instead. I use the North/South lines and draw a line along it. Then using the markers from the FIND SPEED section I draw a line up to and slightly beyound the N/S line.

Then use the protractor to measure the angle. If the ship is heading W, I take the angle and do quick math (360-measurement) and that gives the course.

==FIND DISTANCE==

Draw a circle using the compass from the sub centre. Then draw a line from the target ship to the circle. Simple math at that point to calculate the distance ( CompassCircleDiameter - TargetDistanceToCircle ).

Then again its entirely possible that I am misidentifying the ship as well but I don't think I am.

Any pointers?

I have the HARD settings on and missed 95% of my shots short of stern. I tried about 30 times with a single Transport (spawned by me) all about 90 deg shots. I tried to change aob + degrees ahead of the transport and it did not change any results at all, I tried slowing the transport and no change. I tried everything to change the torp direction, AOB/speed/Ship course but nothing worked. So I finally got fed up and set up a new game with easy targeting just to see what happens. Well after waiting awhile for the solution percentage to rise to about 90+% I fired 1 torp and got a hit the first time. So somewhere my calcs are off in hard mode. I checked the solution that the crew came up with, but I did not see what calc. was wrong that I was doing before. I will keep checking, I have seen/read many videos/tutorials and followed them exactly. I'm sure I will find the error.

Update: I did my own calcs again and got a hit. (I think my course calc was off) :(
I got 2 diff hits based on my own calcs ...... looks like i found my err (me) :)
Note: The only main difference was "easy" vs "hard" solution settings.
Will be trying the TDC device settings next.
