Incident Photo of The Week - Head On Collision

Speculation only. In river accidents the rudder is always the suspect. If found to be operationally sound and orders were appropriate, the next area of investigation are the channel dimensions and a querry on bank suction. A right hand turning propeller smelling a good bank gradient can sheer a ship 30 degrees easily even with hard-over opposite rudder. Instinct is to increase speed; it only exacberate problem, I'll bet on bank suction
