What is tug RT Adriaan trying to do? It seems to be moving in an arc of constant radius centred on the bow of Muros, and facing away from the ship, which I interpret as being attached by a tow rope, and trying to pull the bow sideways to the SW into deeper water. But it is now low water, so if Muros did not move at high water, what is the point of pulling now? Perhaps it is just a convenient way to keep attached and wait for the next high.
