General Duties of the QMOW, Continued Example:  The  ordered  course  and  speed  is  080°  at  10  knots.  You  have just  plotted  the  1000  fix,  which  shows  the  ship  right  of  track.  What  is the  set  and  drift?  Refer  to  the  following  table  and  figure  11-8  to  find set  and  drift. Step 1. 2. 3. 4. Action Find  the  CMG  and  SMG  between  the  0900  (A)  and  1000  (C) fixes.  You  can  see  the  CMG  =  089  and  SMG  =  11.2  kn. Using  a  parallel  ruler  or  PMP,  find  the  direction  between  the 1000  DR  (B)  and  the  1000  fix  (C).  As  you  can  see,  this  equals 140°,  the  ship  is  being  set  in  the  direction  of  140° Using  dividers,  measure  the  distance  between  the  1000  DR  (B) and  the  1000  fix  (C).  The  distance  is  equal  to  2.0  nmi. To  find  drift,  divide  the  distance  by  the  time  between  the  two fixes.  For  our  example  the  time  between  the  two  fixes  is  1 hour.  Drift  equal  2.0/1.0  or  2.0  kn. Note:    You  may  measure  set  and  drift  over  many  hours,  if necessary.  For  example,  if  distance  =  8.4  nmi,  time  =  7.5  hours what  is  the  drift?  8.4  +  7.5  =  1.12;  drift  equals  1.12  knots Figure  11-8.  Finding  set  and  drift. 11-38
