The next project is one of the ships of the Gulf Fleet- the last ship of the old style to be built in the Confederate Navy.
Now, the overhangs and citadel are giving me fits... any tips on how to make these look right?
Also, I want her to have barquentine rigging; I think the layout of the masts is correct, but will the sails have enough area to actually provide sufficient power to move the ship? Are the spars on the foremast about the right length? Are the booms and gaffs on the main and mizzen masts about the right length for their height- or should they (or the sail itself) be shorter/thinner?
Additionally- especially to Redhorse, Alvama, and WhyMe (who do a lot of 'Age of Sail' and 'Transitional' ships)- how much weight should I allot for the sails, rigging, etc? I have 32 tons available... and will install a few torpedo carriages before I get finished, so I have to reserve some weight for them as well.
I want this ship:
To resemble this ship:

but I want the heavy guns on the upper gun deck rather than the lower one.

Oh, are there any pictures/descriptions of what a vintage 1870's 'Torpedo Carriage' (as opposed to a 'torpedo tube') might look like?
