Question 510Deck Safety70% to pass
The Scharnow turn should be used in a man overboard situation only when _______________.
AI Explanation
The correct answer is D) there has been sufficient time elapsed since the man went over to complete the maneuver.
The Scharnow turn is a specific man overboard recovery maneuver that is only recommended when there has been enough time since the person went into the water to safely complete the turn. This allows the vessel to make a tight 360-degree turn to return to the person's location. The other options are incorrect because the presence of twin screws, keeping the person in sight, or immediately starting the turn are not the key factors in determining when to use the Scharnow technique. The elapsed time is critical to ensure the vessel can successfully execute the maneuver and recover the person from the water.
