| 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. |

The
basic configuration is for full range imaging. Removal of the
forward scan sonar system allows for two additional configurations:
Side scan and internal camera imaging, or removal of all sonar
for basic inspections and surveys. Like all Nova Ray® ROVs,
this model can accommodate user defined add-on technology. Mission
critical inspection and tracking projects will stay on course
with this portable workhorse.
