question about torpedo depth & under the keel shots.

[gutted]

In SH3, the norm was to set the depth of the torpedo ~2m more than the listed draft of the ship for a good keel shot so they will pass under the ship.

.ie
7m draft = 9m torpedo depth.

-------------

In SHIV with the mk.14's it's possible they'll run up to 3m deeper than what you set them for.

so:
7m draft = 6m torpedo depth ( 7m draft + 2m under, -3m for the variance in depth). so in essence 1m less than the listed draft.


am i correct in this assumption? aren't we still trying to get them ~2m under the ship?

when if first started playing SHIV some years ago, i would set 2m more like i did in SH3 but go so many non-triggers, that i quit using them and just went for contact. wasn't till much later that i found out about the depth problems. but lately i've been having alot of calm seas, and am looking to finally start trying out these magnetics again. but i see threads where people are saying to set them 10' feet (3m) less then the indicated draft.

so

7m draft = 4m depth.

wouldn't that not ever have the torpedo pass just under the ship for a magnetic keel shot? wouldn't it always still hit the ship?

------

so if you were using imperial measurements (which i dont)... there's a 10' possible depth variance. we want it to be within about 5' under the ship.

20' draft = 15' torpedo depth. yet.. i see threads where peopel say to use 10' for this example. why set mag's if you aren't even trying for an under keel shot in this case? with a 10' setting you're either going to hit the ship right in the middle.. or you are going to hit it squre on it's keel... never underneath the keel where you really want it.

or am i wrong?
