Start in 1860 to have a better ship, more useful at the begining of the game, in1880.

I agree, though maybe it is more of a try, to get a feel of the rules. Looks nice. Not 100% sure about the barrel lengths for those days. Seem a tad long. Also, if the vessel has rigging, the miscellaneous weights might not be enough. A 3609 ton ship requires 234.6 tons below waterline and 54.2 tons above deck for full rig or 144.4 tons below waterline and 36.1 tons above deck for brigantine rig.

I know that the barrels of those guns were pretty standard in the 1860's... so he should be good there.
The waterline belt is a nice touch- most ships of that time also sported some limited battery armor as well... or even simply an armored citadel around the guns/magazines.

A nice little 'experimental' ironclad... though the first armored ship in Europe was about a decade later.
However, since the Asians originated the concept almost 500 years prior... no real problem there.

1960?!? Oi! No cheating here!!  ;D

For naval guns, with a few exceptions that just go over the 20 calibers, guns appear to be between 10 and 20 calibers long. That seems quite obvious and logical with muzzle loading guns. The longer the gun,  the further you have to haul it back in order to reload it.

Few examples:

68-pounder (1846, 8.12"/16 cal)
RBL 7 inch Armstrong gun (1861, 14.2 cal)
RBL 40 pounder Armstrong gun (1860s, 4.75"/22.4 cal)
RBL 20 pounder Armstrong gun (1859, 3.75/14.4 cal)
RML 64 pounder 64 cwt gun (1865, 6.3"/15.5 cal)
RML 7 inch gun (1865, 18 cal)
RML 9 inch 12 ton gun (1865, 13.9 cal)

Dahlgren 32-pdr. of 27 cwt. (6.2 inch/15.1 cal)
IX-inch Dahlgren shell gun (1855, 14.5 cal)
X-inch Dahlgren shell gun (1855, 14.6 cal)
XI-inch Dahlgren shell gun (1856, 14.6 cal)
XV-inch Dahlgren shell gun Short (1862, 10.8 cal)
XV-inch Dahlgren shell gun Long (1864, 11.9 cal)
Dahlgren 50-pdr rifle (5.1"/21 cal)
Dahlgren 150-pdr rifle (7.5"/18.7 cal)
Dahlgren 12 in. rifle (14.8 cal)
4.2-in Naval Parrott (24.3 cal)
6.4-in Naval Parrott (21.6 cal)
8-in Naval Parrott (18.3 cal)

Canon obusier de 12 (1853, 4.62"/14.3 cal)

Fixed... I was in a hurry to get my wife off Skyrim when I typed that.
AS these would be comparable to the smaller Parrott guns, I think 35 caliber would not be too large.

[Walter]

Having taken a quick look around I have not run across any 1865 or earlier naval guns in excess of 25 calibers.

[Carthaginian]

DAMMIT.
I have GOT to stop typing at 0100.
I meant 25 calibers.
Sorry guys.

Less late shifts, more coffee needed.

Thank you all on the comments, the BL loaders are indeed modeled on the Naval Parrots and the ship I was trying to do was the HMS Stockholm but as you can see I am still a bit hazy when it comes to sim ships of this era
