Question about hull depths?
 
So with magnetic torpedoes you're supposed to actually aim under the hull. My question is how do you know this distance for sure? I mean I look in the recognition manual and identify the ship, but do one of those numbers tell you how far below the waterline the hull is? I always just look at the picture and try to estimate how manymeters below it is.

Also, I tend to leave my T1s on impact and magnetic. I've had cases of aiming a little too low and the torpedo passing underneath. How come it doesn't explode? I assumed I was just doing it wrong.

the number you need is from the DRAFT

take that number and put your torpedo depth 0.5m deeper.
magnetic pistol.

for example a Pyro Ammo cargo has a draft of 9 meters
put your torpedo to 9.5m

use only in calm / minor seastate
in moderate and heavy the chances that the ships bounces too much that the torpedo will go under it.

Draft, got it. See, I thought perhaps it was one of those, but the term draft to me does not mean depth under waterline. But then again, I'm ignorant in the ways of sea life.

And that was probably why the one time I was hoping magnetic would work it didn't. The sees were rough and I think the ship ended up bobbing too high.

Thanks very much sir! :up:

The draft of a ship's hull is the vertical distance from the waterline to the bottom of the hull.

cardician what Hunter say is exactly what you need to do. One thing you must bear in mind though. Big ships are difficult to sink with a single keel shot unless is very well aimed. Usually they require two (or I'm crap at magnetic attacks :p ). Also make sure you're using them in good weather conditions as Hunter suggestd to minimise the chances of premature explosions and torpedoes bouncing off the hull.

Just out of curiosity cardician....what draft were you thinking of...the windy one or the drinkable one (draught) ? ;)

cardician 03-29-07 07:04 AM

Yeah, here I was thinking they were talking about the kind of German ale the captain of those particular ships preferred. Silly me :p

No really, I just didn't know that's what draft meant. Not that it shouldn't mean what it does, I'm just too ignorant to even know what it should mean.

So if it is drafty outside I should not use draft, but when it is not drafty I should use draft? :doh:

I am going back to pong:oops:

I've had good success with magentic shots, even in rough weather by disregarding conventional wisdom.

I calm weather I set the torp to 1 meter below the draft. In rough seas 1.5 to 2 meters. This prevents prematures.

I make sure the torpedo will run diagonally along the hull with an AOB of 60 degrees or less. This will insure 1) torp runs under the ship long enough for the pistol to activate. 2) it will explode under the engine room and sink the ship :smug:

Good advice. 0.5m is too close - it might get knocked in the bobbing of the keel. I always do 1m below, and have great success.

I tend to agree :yep: I go for the + 1 metre :arrgh!:

im not really a good kaleun, but im trying ... id vote for the draft+1m runningdepth too.
