Torpedo bulkhead 14.63m is wrong


"Miscellaneous weights: 0 tons, 0,0%"

no update possible...

Torpedo bulkhead 14.63m is wrong

I do not think that is wrong, the TB continuous upwards behind the main belt, forming a splinter shiled. I also suspect that the deck is situated on top of the belt, so the TB reach it.

[Borys]

Ahoj!
Well, this design was made very, very quickly, so I missed the Misc. weight :)

As to the TB - I allways use "from bottom to weatherdeck".  To represent splinter/fragment catcher.

As:
1 - I use TB only on battleships;
2 - I armour the sides up the weatherdeck;

this works.
This time, with no Upper Belt, I'm not quite sure what exactly the TB sticking above the MB is supposed to accomplish :D

Well, a lesson in "do not upload ship which you made in less time than it took to upload" :D :D

Also the Armoured Deck is a bit anorectic ...

Your design may be intimidating, ambitious, and flawed, but at least it's Safe For Work.

[Borys]

Ahoj!
I wonder what will search engines and various filters think of a Nverse newspaepr title:
"KKK soaps slips for SMS Wet Split Beaver"?
Borys

[The Rock Doctor]

That headline is all kinds of wrong - but apparently the firewall here allows it through.

There's absolutely nothing wrong with that headline. A proper English sentence.
