 Description
-    Sea Keeping Analysis (SKA) 6DoF motion function.
+    Tabulated 6DoF motion function.
 
     Obtained by interpolating tabulated data for surge (x-translation),
     sway (y-translation), heave (z-translation), roll (rotation about x),
     pitch (rotation about y) and yaw (rotation about z).
 
-See Also
-    SDA (Ship design analysis) for 3DoF motion.
