I figured that one way to make the Reuse look like a larger vessel was to make her look taller. To do this I added a bulwark around the bow gun and a railing around the boat deck. Its a little low and only 1 rail instead of 2 but I think it helps. The bulwark should really be wood with gunports but there's not much room and it would be tricky to match the curve of the bow so its going to look more like steel plate.
After reading a bit about early paddle gunboats and looking at pictures I decided I need to build a sliding pivot gun mount for the 32 pounder bow gun. Still working on that part.
To make the launch look smaller I started by cutting down the bow a little and adding a small focsle. Then I moved the funnel from ahead of the boiler to on top of it to make it look smaller and to make more room. Then I added a bench in the stern with a tiller. Looking at the picture, I think I'll extend the gunwale to the stern.
Next week I'll cast some of the zinnbrigade seated aryillerymen and convert one to a coxswain and maybe a couple to marines.
I think I could probably use maybe one more steam launch and two boats to be towed or rowed. These latter will have a bow and stern like the steam launch but with low gunwales and no boiler.
