Question 514 Deck Safety

The correct answer is B) the vessel has turned 60° from her original course. The Williamson turn is a standard ship-handling maneuver used to turn a vessel around in a tight space. The initial action is to put the rudder over full until the vessel has turned approximately 60 degrees from her original course. This allows the vessel to begin the turn smoothly and gradually, rather than executing a sharp, immediate turn. The other options are incorrect because: A) a reciprocal course is not the criteria for the initial action, C) 90 degrees is too much for the initial action, and D) the emergency turn signal is not relevant to the initial Williamson turn procedure.
