Scharnow TurnThe Scharnow Turn is a maneuver used to bring a ship or boat back to a point it previously passed through, often for the purpose of recovering a man overboard. The Scharnow Turn is most appropriate when the point to be reached is significantly further astern than the vessel's turning radius. For other situations, an Anderson turn or a Williamson turn might be more appropriate. - Put the rudder over hard. If in response to a man overboard, put the rudder toward the person (e.g., if the person fell over the starboard side, put the rudder over hard to starboard).
- After deviating from the original course by about 240 degrees, shift the rudder hard to the opposite side.
- When heading about 20 degrees short of the reciprocal course, put the rudder amidships so that vessel will turn onto the reciprocal course.
If dealing with a man overboard, always bring the vessel upwind of the person. Stop the vessel in the water with the person well forward of the propellers.
