The vr32 class DDs built or being built by Romania do not conform to the Gentlemen's Rules, the flaw being in the cross-sectional strength. This flaw was recently brought to my attention, and here is the revised design which Romania will rebuild the vr32s to.

It's good with me.

She might be good for you but she is not for me. A cross-sectional hull-strength of 0,42 can hardly be ignored, can´t it? O.o

Actually it is 0.50 now. It was 0.42.

Exactly. Which is why it's being replaced. Note that the Springsharp up top is for the replacement, the 'sharp down below is the flawed one which is being replaced.

The top SS is what the vr32 is being rebuilt too, the bottom SS is what is found currently in the encyclopedia, as well as this thread. I quite freely admit the mistake was mine, although others did post in that thread and no one caught it. If I have to, I am even willing to scrap the ships and build new ones, as well.

I have no problem if You just edit the encyclopedia entry as long the

remains

I was wondering if I could have some sort of consensus on this from the mods so I can post my 1938 reports for Romania? Essentially, option a) is rebuilding them to the above design (sim 1), while b) is scrapping them then building to a new design (not sim 1 or 2). I think you can all guess which option I would prefer, but I am willing to go with either.

Just build to the above specs; if the new ship is larger, add the remaining tonnage ASAP.

Works for me.
