Greetings- Well, I've been read through the GWX 3.0 Gold documentation, and also their reminder about the old "stock" damage control, and they state, that few merchant ships need more than one torpedo, and few ships need more than two at all.
Well, I dont mind playing hard, but:
Granville-type merchant:
------------------------
After two magnetic impact T I. hit, (both left really big holes under-and-on-the-side, one of them is 1.8 meter below, the other is 0.8 meter below draft) It continued its course, a little slower, zig-zagging. After many hours of waiting, almost a day, in max. CT, I.. er... Managed to loose it, as I stared too mutch to the ship from a closed by camera, and the U-boot drifted away.. After changing view back to the U-boot, I wasnt able to find the ship anymore XD still, it never sank.
SMALL merchant:
------------------
As It seemed to me, that impact damage somewhat more effective in GWX O_o than magnetic, I tried that:
Ive hit the small merchant in several reloads with one torpedo, and started to wait. I never acquired any critical hit, so I reloaded the game last time, and hit the ship near its bow. (between bow, and middle line) then I've waited for like almost a day, When I started to RAM it. (rough waters, no gun) I managed to ram it near diagonally on 13-15 knots, at least five times, near the hole on its forepart, and all the times pushed its bow below waterline, as my U-Boot was actually on top of it...
Still no success, and flooding seemed not to affect it. As the same with the Granville before. So I finished it off with a second torpedo. Small merchant: two torpedo at least. .. Granville: needed more than two... These are rather SMALL merchants...
Another funny thing, maybe because the engine feels it as an accident, as no shots was fired to it earlier, but I managed to ram into a ship, not longer than the U-boot, propably a really small merchant, which instantly started to sink.
Blown up, and sank. But no entry in the captain's log
I presume if I could manage to hit it first even with a single AA shell, it logs it.
It was not that mutch smaller than the small Merchant, which withstanded 5-6 well developed ram, after a torpedo hit...
So: My question is: what happened? Why I cant finish off even a small ship with one torpedo UNDER THE KEEL? ^^ or Why a 4000-4500 ton merchant needs 3 torpedo? I experienced many cases like this, I just doesnt know how to kill in GWX... And many times you dont have this mutch of a time, and chance to sink something... In reality, even the biggest merchants sunk via 1 torpedo, or maximum two.
Wheres the flooding? No clue after many many hours...
Usually I fire under the keel (draft) from 0.8 to 1.8 meters when magnetic, and I fire above the keel with 2-3 meters when Impacting.
