@Ronald yes I’m pretty sure they’re metal. I have everything for the rudder assembly for the 2 piece hull. But did not realize the 1 piece fiberglass hull is different for the rudder mounting. I’m thinking I could use the set up for the 2 piece hull. But would rather have those 2 pieces. We shall see. Thanks

Those are very unique to that particular style of tugboat. Never having built one of these Dumas tugs, would these be White Metal castings?

I could imagine they are white metal casting which with some careful fabricating, you could duplicate them using brass bar, brass rod and brass tubing?

These 2 pieces

Please post a picture of the parts needed as seen in the plans.
