 winches treatment (slope=0. 06101 than during the sym- 

 metry treatment (slope = 0.0381). Similar effects were 



also detected for crabbing (slopes = 1.2355 and 0.8493, 

 respectively). Current speed in the direction of the tow 

 affected footrope SD only during the symmetry mode. 

 Heave, crabbing, and current velocity had no effect on
