Mike, there's a convention that cross-sectional hull strength on torpedo-boats and similar vessels ought to be 0.50 or higher - not just the overall strength. If it drops below, the hull is considered fragile and greatly at risk of failing. I've inherited a number of light craft with this issue and can look forward to a few sinkings before I get round to replacing them. You might want to avoid the issue altogether...
Thanks for the heads up, a slight pain as the over hull strength is shown on each tab
while the cross sectional hull strength is on just the one tab.

In deck mounts?
i really think you should fix that, or the guns will be almost useless, as deck mounts are not power assisted, so the crew have to manualy carry the 216kg shells and it charge from a deck locker or from the magazine to the gun. the rof will in be far less then 1 round per minute.

Ahoj!
Mike, Coles/Ericsson turrets are a bad, bad idea. Maybe you clicked in the wrong place, and you wanted turret&barbette?
That change would allow you to increase your misc. weight, so that you could carry Marconi and torpedo reloads?
