Here is a photo of a Lindberg Monitor I built a while back. While my normal genre is armor, the ship is like a tank and I guess it floated like one as well. Unfortunately, I broke off the forward flagstaff and the carpet monster carried it off, but I'll replace it with something.
I'm not sure of the scale, but the kit came double boxed with the Merrimack on a blue vacuformed display base. I added strip styrene to the top of the turret to give the appearance of deck planks, but the kit is otherwise built out-of-box.
