EAR-Controlled Technology Subject to Restrictions Contained on the Cover Page.
Profiling Depth: The nominal specification is 500m at 8kts, which requires ~1500m of line. As the ves-
sel speed decreases, the achievable cast depth increases up to the maximum pressure rating of the probe
for long stationary casts. As very deep casts are much longer in duration, the vessel cannot be moving ap-
preciably as this will waste available line to account for the movement of the ship. As the vessel speed in-
creases above 8kts, the achievable depth decreases to maintain the profiler in a safe condition during re-
covery (low line tension). The maximum vessel speed under normal operation is 12kts. The motor rpm
and braking time may be adjusted by the user to suit the survey conditions.
As long as the vessel retains a nominal forward motion to prevent entangling of the line in the ship propel-
ler. The maximum profile depth is then limited by the amount of line on the rapidCAST spool and the
probe pressure rating of 2000m.
Line Type: Hollow Spectra line of 500lb breaking strength with an 800lb leader.
Line Length: The maximum amount of line that can be loaded is about 3000m. Typically, 1500m is
used. Line length does not directly correlate to maximum cast depth underway. This depends on ship
speed because the total line paid out is a product of ship movement and probe depth.
