When I first read about teh Dich O'Kane method, I thought "this is about the relation between the speed of the target vessel and the speed of your torpedo".
Yet in Rockin Robbins guide I only found two shooting bearings 10 deg for fast and 20 deg for slow torpedoes.
So I set out calculation my own shooting bearings at target vessel speeds using the following formula:
tan(a)=Vtarget/Vtorpedo
a = invtan Vtarget/Vtorpedo
where a = angle and V = speed
So I came up with a nice table with shootingbearings for speeds from 1 to 20 knots for slow and fast torpedoes.
As it turned out my whole table was a waste of time. You know why?
Because your so damn close (> 1100 yards) that rough estimates like 10 deg for fast and 20 deg for slow torpedoes do the trick.
Since the Cromwell attack is based on the same principle i.e. the relation between target speed and torpedo speed, you don't have to worry about precise schooting bearings if you take care that your in a well let's say 1500 yrd radius from your target.
I use the Dick O'Kane method frequently and it works like a charm. It also gave me insight in how to figure out the AOB, which led me to use the Position Keeper.
The PK is my friend now and I seldom miss. The only thing that I have trouble with is shooting two convoy targets at a time with the PK. I saw a videoguide for it once, but I can't find it anymore. Do any of you guys have some advice on this for me?
