Here is my partial build model of the Frederick Mistral. The kit was made by Anfora and for some reason they call it "Duna".

What stopped me from continuing was the rudder control. This was via a chain that ran on both sides of the deck just inside the gunwale. This ran from the pilot house back to a cam like arm on the rudder post. there were a series of pulleys along the inside of the gunwale to keep the chain in place.

My problem was that I could not find a small chain that could withstand the tension.

I made a lot of corrections/modifications to it following photos of the real tug. This included many new/replacement parts that I had 3D printed by Shapeways. They are shown in the last three photos.

This is an interest tug *(the historic original is still floating on the Danube River) and I wish I could finish it.
