Ship space, strength and comments:
Space - Hull below water (magazines/engines, low = better): 37,7 %
- Above water (accommodation/working, high = better): 171,3 %
Waterplane Area: 5 409 Square feet or 502 Square metres
Displacement factor (Displacement / loading): 274 %
Structure weight / hull surface area: 59 lbs/sq ft or 286 Kg/sq metre

- Overall: 1,54
Hull space for machinery, storage, compartmentation is excellent
Room for accommodation and workspaces is excellent
Ship has slow, easy roll, a good, steady gun platform
Good seaboat, rides out heavy weather easily
You could get a LOT more out of that. Maybe increase the speed a little and add more guns, maybe a few heavies.
It's a river monitor, not a blocus enforcer. :D
For the heavy guns, I think I can use 37 mm ( like Hotchkiss Model 1916 ).
Still, maybe you could add a few more knots, or even better, add a few companies of transport capacity. And if thats aimed againist the Zionists, their gunboats are half of the size of yours and mount more guns.
The ships of New Zion ? No, they can't attack my monitors. For a good reason : it's not possible to sail from the actual Uganda to Khartoum.
Still, very underperforming.
I agree. It's a monitor and Egyptian technology is weak, so I preferred to insist on the armour rather than on the engine.
The thing is, you could put a lot more armour on that ship then you have.
Yep. But it's only a first try.
So, more guns, more armour, more motorisation. Another ideas ? :D
EDIT :
Third try, with Sachmle's help :
...
Au pire on ne les achètera pas, s'ils n'existent pas!
Much better. You could possibly increase the speed a little, but still, a much better ship.

I'd fix that first, then see what's left over. If there is any, you may want to lengthen the end belts.
Oops, what a nice forget... but not for Egyptian crews. :P
