|
|
|
Depth
|
Depth Rating
|
305meters (1,000 feet).
|
|
Currents
|
Stability in Strong Currents
|
Arcuate wing design counters destabilizing effects of
cable drag. Results in faster, more stable performance in
currents with less cable.
|
|
Maneuverability
|
Dual Operation Mode
|
Can be towed or use thruster power in strong currents.
See Speed for knots.
|
| |
Speed
|
Up to 9 knots in currents under tow. With thrusters:
4 to 6 knots (1/4 or 1/3hp respectively)
|
| |
Cable to Depth Ratio
|
Under tow, Nova Ray® provides deeper operation with
less cable than other Underwater Towed Vehicles (UTV). Nova
Ray® can operate up to 70% deeper than conventional
UTV systems using the same cable length. Under tow, operates
at a ratio of 2.38:1. With thrusters, the Nova Ray®
can reduce the ratio to 2:1. With less cable, the Nova Ray®
system is lighter, smaller and easy to deploy anywhere in
the world on a rapid response basis.
|
| |
