The '''Scharnow turn''' is a manoeuvre used to bring a ship or boat back to a point it previously passed through and was developed by and named for Ulrich Scharnow. The primary advantage of the Scharnow turn is that after the turn has been completed, the vessel will be proceeding on a reciprocal course in its own wake.<ref name="SeamanshipNotes"/>
 
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.

Generally, a Scharnow turn involves 1.) placing the rudder hard over in any direction, 2.) deviating 240 degrees from the original course and then placing the rudder hard over to the opposite, 3.) when the heading is 20 degrees from the reciprocal course, the rudder should be placed amidships and engines stopped to bring the vessel alongside the casualty.<ref name="SeamanshipNotes"/>
