Thanks Jimbuna...been looking for it for two days and couldn't remember where in the deuce it was.

SINK EM ALL!!

Thank you CaptBones for the informative post

When using an impact pistol (contact detonator) make your aim point anywhere but amidships (directly under a mast or Kingpost, or right ahead of the bridge seems best) and be sure you get as close as possible to a 90deg weapon track to the target (torpedo hits at a right angle to the hull). It should be noted though; for a time, the real world U-Boat commanders' experiences with the impact pistols were totally the opposite. The better the weapon solution, the more likely the pistol was to fail. In addition to the other failure modes, a "perfect" 90deg impact angle would result in the inertial firing mechanism failing, getting crushed instead of detonating the warhead. That was also exactly the opposite of the early-war problem the US Navy experienced with its contact detonators. Anyway...good hunting everyone, sink 'em all!

Intresting. I don't remember where, but I red that US Skippers where taught to fire (for contact detonations) with an AOB of 80° or 110° and not the usual 90°.

Anyway, about nice spots to aim your eels, I found this page very useful: Ship Weak Spots

German torpedoes had a contact detonator that would slide directly into the tube it was mounted in and set the torpedo off. If it struck at an angle it could bend, thereby not detonating.

US torpedoes had the opposite problem. The firing pin had guides to keep it steady. The force of the torpedo hitting the target was too strong for the spring to handle, and the guides would bend. When striking at an angle the force was lessened, and the guides kept the pin steady.

Hey Sailor Steve, thanks for the info!
Now I remeber where I red that thing about preferred torpedo firing AOB, it was mentioned in the Submarine Torpedo Fire Control Manual doc at hnsa.org.
But you explained the ratio behind it that I didn't know: many thanks
