About the escorts though, I know they can listen just like the sub can so if I'm making little noise it's difficult to hear it, but their sonar pings can pick you up at anytime right? That's why I'd assume it's such a bad position to sit with your side pointing straight at them while they're approaching as it provides a large target for their pings to hit off of. And as I said earlier, I've had them ping me at some pretty deep depths, between 100-160 feet isn't always safe by the feel of it. I've even had them ping me below the layer as low as 260 feet. I've never tried deeper then that. I forget which sub I'm using. Not the porpoise and not the one after that. I think it might be the Sargo class. Not entirely sure how deep she can go without damage but perhaps I'll test that out sometime.

The thing is, escorts won't usually ping you unless they know you're there. Also, you can make a variation on this technique by pointing yourself towards the escorts and the once they pass turn towards the convoy. I just prefer to sit under and broadside to them as it takes less time to fire and evade.

But anyway, I just sank the one large freighter in a convoy and am attempting to duck away from their escorts and put myself into a position to shadow them until I can get into a position I can strike from again. I'm curious what the measurements translate to. From the video it sounded as if every 2000 yards equaled a NM? Is that correct? Also I think he measured nautical miles traveled to equate into knots, but I want to be sure. Lets say a ship travels 1 NM between the time I first checked him and the second. How do I translate that properly into an actual speed?

I myself do not know the conversion to changes yds into NMs but with a quick check you can find that out. Congratulations by the way on the kill
The way you measure speed is by taking into account distance travelled by the timeframe it took. For example, if in 15 minutes you measured your target ad travelled 1 NM, he would obviously be going 4 knts (nautical miles per hour). Thus, usually try to take readings between times you can quickly multiply to an hour (ie: 5,10,15, etc minutes.)

Also, I've read some of the issues with the early torpedoes and I've restricted myself to contact only detonations almost exclusively and keeping the depth at bout 5-10 feet above the bottom of their ship. That's called the keel right? I believe that's cut down on the premature detonations I've had and you'll have more duds when firing with fast speed but it'll give them less time to spot and evade them. Obviously all shots should be as close to 90 as possible. Does that all sound about right?

Sounds about right to me, HOWEVER. With contact pistol set on, make sure to set the depth as high as you can (keel shots are for magnetic torpedos). Also, by 1943 most if not all preemy's or duds will have been sorted out.
