I learnt many years ago to use just rope as a rudder.

The idea is to tie a lot of rope into a man size mess of rope.
Then from that mess of rope, two cables come to port and starbord winches.

You can, by reducing the lenght of the rope to one side, move the mess of cables to that side and thus cause more drag to that side of the boat, an cause a slow turn.

You can motor an sail with it. Guaranteed.

what you would call that in the US I don't know, but if I translate, its somethimg like "drag drone".
