I will revise the draft and the design.

@Hrolf:
You are naturally right. Even if the Pirates are destroyed, the ship is still there. Of this reason the ship should be able to consist also against other warships. Thus armoring must be strengthened.

@Hoom:
Good idea. Perhaps I will consider it.

The ship needn't more speed, because no other chinese Ship is faster than 29kn's !

further changes:
Placement of the 88er corrected
Freeboard lowered
Shells per main gun lowered
Torpedo bulkhead added
Armour improved

Then i try it again.

but .....

isn't the belt armour of 152mm a little bit exaggerated ?
And do i really need a conningtower armour of 152mm ?
Or should the belt armoring and the bridge armoring be identical?

There are probably still many things which I have to learn. ;-)))
