I usually get so close it's at :yep point blank range................ :lol:

I have the same problem. Playing the GW mod. I just adapt to the offset according to the methods described above. I wouldn't mind it if this were an intentional effect to recreate any of the actual difficulties experienced in manning a deck gun on the high seas . . . but this just feels like a bug.

I've also noticed that I can't lock my view on ships (using periscope or UZO) outside of a couple thousand meters or less. I believe I have the realism set to allow locks on any visible ships. Again, this is a minor annoyance. Bug or not, I can deal with it. I've even learned to like it!

I have the same issue but it only happens at night. I just compensate for the side it is not hitting on.

I once had the same problem but it only occured in the two magnified views. The distance view which I almost always use was right on target. The next time I started in mid patrol, the magnified views were also right on target.

Might this be a sabatage or mechanical problem caused by SH3 Commander?

Yes I have noticed it too when zoomed in
Usually pulls to the left I have noticed

I get this and I do not have the SH3 Commander. We can rule that out. :damn:

The sabotage is disabled in the SH3Cmd by default. Unless you enable it you don't see the effects, but I don't think this problem is linked to SH3Cmd

I have never run into this problem, in SH3 (over 50 missions) or TGW and I've used the deck gun many times. In fact, in TGW, after I sent 6 fish into a small merchant in my first mission, I surfaced and started shooting at it from the deck gun to sink it. I used all my ammo and I only missed a couple times, but thats because I was mocing toward target.

This was before I knew about the difference in the sinking time difference between SH and TGW :rotfl: :rotfl:

WINDS SPEAKS HERSELF IN THIS WAY!!! The cannon ball, like other objects, is affected by wind and other factors. I don't think this is a bug, but it brings more realism:sunny:

The same for AA guns, when you ask your crews to man the AA guns, they usually aim at and shoot a little bit higher than the plane. Because the motion of bullets is a parabola (projectile motion - Advanced Physics), so it will hit the plane will it falls

Yup and 88 Deck guns did NOT have the same Velocity as it's 88 AA/AT counterpart.
Plus where as the 88 AA had a stable platform ( the ground= not moving ) and only had to contend with the motion of the target and wind.Also you see the 88 AT firing from a Static position.The 88 deck gun had to contend with the motion of the submarine + the motion of the target+ the wind+ lower Velocity, so it all adds to the factors Why the 88 DG is not as acrurate as it's 88 AA/AT counter part.
