France 1870 restart

[Jefgte]

Given the way the mitrailleuse wsa reloaded, you'd probably want more barrels than 5, since after 5 rounds you'd have to stop firing and reload.  I'd recommend going with as many barrels as SS allows, which I think is 10.

5 bullets is the standard reload system for De Reffye gun & used in the infantry too.
So 2x5 could be correct for "la Marine"

A question on this vessel: in a France without colonies, what's her role?  I mean, the class title suggests "station gunboat" (I'm guessing a bit, since I don't read French), but where would ships of this type be stationed before colonies are acquired?   Or am I reading too much into the title?

[Jefgte]

"Canonnière de Station" could be "Canonnière de Ligne" or Canonnière d'Escadre => Squadron Gunboat
...

The USS Hornet, HMS Amethyst, and your Canonnière de Ligne make interesting comparisons.  Amethyst isn't armored at all, which both of the others are, though Hornet and Canonnière de Ligne are armored in a different fashion from each other.  Amethyst has all guns on the broadside, while Canonnière de Ligne has bow and stern casemate guns along with casemates on the sides, and Hornet has pivot guns fore and aft with broadside guns to the side.  Amethyst is 1 knot faster than the other two under steam, while Hornet is faster than either of the others under sail.

I think you may have selected the wrong French restart thread. :)

... and I spot a cross-sectional hull strength value of 0.49...
