Hi, I followed the tred about the paddle steamer with interest. Would certainly bee a project of interest. Quite a few years back one of the members of the model yacht club build a Thames paddle steam tug. These boats were rather narrow in hull form and were by nature not already that stable. I remember vividly the first trails with fixed paddles. The boat insisted in capsizing itself. It proved the case that the uplifting paddle tried to dig itself deeper and deeper into the water and as long there was an equal force on the opposite side things went reasonably ok . But once there was a heel to one side the problem worsened and the result was unavoidable and stopping the engine was the only option to save the boat. In the end the builder had to go the whole way and build in the compensation system for the paddles. Afterwards the boat performed like it was supposed to do. Just some thoughts and observations.
