Eventually Bob Ballard released the coordinates of the Titanic's location. He recorded her coordinates as, stern section sits on ocean floor at 41o43'35" N, 49o56'54" W, boilers at 41o43'32" N, 49o56'49" W, bow at 41o43'57" N, 49o56'49" W. Find these coordinates and trace the outline of the sunken pieces of the Titanic on a chart of the North Atlantic.

How far is it from its plotted course? At the time of the accident, the ship was reported to be at 41o46' N, 50o 14' W. (She was found 13½ miles southeast of the position given in her lastdistress call.)

Today's satellite technology through GPS can pinpoint any position on Earth to within 30 feet. In 1912, navigation techniques of dead reckoning and celestial navigation could only give one an approximate location within several miles of one's true position. So by these perimeters I think you can say for that period of time during 1912 the distance of 13½ miles off isn't so far of.

Is 13½ miles the figure you were refering to? The ocean is a wide, flat, reference free place to locate from. Good day Mate!
