The initial action of a Williamson turn is to put the rudder over full until which of the following?

Correct Answer: Option B — vessel has turned 60° from her original course

The Williamson turn is designed to bring a vessel back to its original track for a man overboard. Executing a full rudder turn until the vessel has deviated 60 degrees from the original course allows the ship to swing wide enough to clear the victim while maintaining a reciprocal heading.
