Offset (m) 



Figure 7 



Mean bridle and footrope distance at each bottom contact sensor position is shown ( + i plotted against offset increment. 

 The means for all values of offset increment were fitted with a cubic spline function (solid curve). Bootstrapped 95':r 

 confidence bounds are shown with shading. Also shown is the mean distance off-bottom for only treatments with zero 

 offset (solid horizontal line) and the bootstrapped 95% confidence bounds (dashed horizontal lines).
