I set to contact and depth of 20 feet on the 14.4 ft draft cruiser and sank it in 2 torps. Both I followed via external view and the definately went under the hull and did not hit it.

I never seen it go 'under the hull', unless you are refering to something else. It is slamming into the 'hull'. You must go below 28 feet to actual go under blue water barely missing.

I cannot confirm your observation. I shot ALOT of torpedos for the one experiment in sub school training.

The Mogami Heavy Cruiser. Draft is stated as 4.4 meter = 14.4 feet.

I shoot torpedos at 28 feet deep hit ever time contact or magnetic setting.

I shoot torpedos at 29 feet deep miss under the hull every time contact or magnetic.
I expected the magnetic to explode, but it does not, nor does contact only.

Slow Mark 14 using auto-TDC no dud setting.

I do see damage under the keel area though, at 28 feet deep with both, nice big hole underneath the hull, not in the side.

The Mogami.sim file has the submerged draught set for 28 41 hex = 10.5. This means the ship is sitting into the water this deep. But according to above, the draft is really 28 feet? the 10.5 in meters ~ 34.3 feet. If you set to zero the ship will float on water.

So do we change the draft? Draught is the actual depth the boat is sitting in. Check it out. You can shoot a torpedo that deep and have it explode every time.

edit: corect value for .sim draft. What do you consider 'under the hull'? They do explode under the hull with massive damage, both contact and magnetic. I do not see any difference between either setting. they both hit or miss.
