Thanks for your suggestion lehcyfer. I may see if I can reconfigure the positioning of the sides when unfolded.
As to the railings, yes,ideally the ship would of had removable iron posts with threaded ends and an eye on the top for railing cables, like those used on th Yankee ironclads. The cables and posts could be quickly removed and stored below when the hip went into action. However, I have never seen a photo of a Confederate ship with railing in place. I have seen drawings of the CSS Virginia/Marrimack with th top casement railings in place though. It could be that the shortage of Confederate iron during the war made railing post too expensive to use. Most of the pictures of Union Monitors do show th use of removable railings and divots.
