Category Standard Feature Nova Ray® ROV Model 2500 Specifications


Depth Rating

305meters (1,000 feet).


Stability in Strong Currents

Arcuate wing design counters destabilizing effects of cable drag. Results in faster, more stable performance in currents with less cable.


Dual Operation Mode

Can be towed or use thruster power in strong currents. See Speed for knots.



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.



DC brushless rare earth motors. Two (1 port; 1 starboard) magnetic drive. 1/4 hp standard with 150 volts DC. Optional 1/3 hp. Propellers and Thruster Guards: 75mm for 1/4 hp., and 90 mm for 1/3 hp. Guard is impact resistant HMW plastic.
