For the two-dimensional paravane rig, the vertical suspension was as 
described for the one-dimensional rig. The horizontal spacer lines were 
also the same, with the exception that to maintain the distance at right 
angles to the direction of the spacer line, paravanes were used at the ex- 
treme ends. These produced an outward drag which pulled the gauge blocks 
away from the charge. Distances determined in this direction were not cer- 
tain because of the bow introduced into the cables by their resistance to 
the water as they moved through it. 
15. Electrical cables and their suspension 
The electrical cables were led back from the pilot gauge and from the 
two piezoelectric gauges nearest to the charge by attaching them to the 
spacer line at intervals with friction tape. At a point 20 ft forward (to- 
ward the RELIANCE) from the second piezoelectric gauge (Fig. 3) the cables 
were led to the surface along a drop line from a surface buoy, and then back 
to the connection barrel supporting the lead weight. Electrical cables from 
the two piezoelectric gauges farthest from the charge were led forward (away 
from the charge) to a point 30 ft from the farthest gauge and then were led 
to the surface along the drop line supporting the lead weight. At the sur- 
face float (comection barrel) the cables were connected to patch cords and 
were lead back to the vessel along the surface attached to a manila line 
which took the strain of the gear. Fourtcen-in. spherical steel floats at 
intervals of about 60 ft buoyed the rope line and the electrical cables, 
At the RELIANCE the electrical cables were attached to a large reel (Fig. 30) 
where connecting patch cords leading to the electronics cabin were plugged
