Design Details
There are many key points behind the creation of an arcuate winged ROV but primarily the arcuate wing uses design over sheer weight to solve issues with umbilical cable drag in strong currents. The design counteracts the lifting force of the umbilical cable (also known as tether) with downward force when the control surfaces are properly applied. The speed of the ship or current has little effect on the operational stability of the vehicle. The arcuate wing has proven to increase cable use efficiency by as much as 75% and reduce the amount of cable necessary to operate or tow at depth.
The physical dynamics of the arcuate wing creates a stable instrumentation platform and allows for maneuverability. This increases system effectiveness in high currents and cross currents when towed or using thruster power. There is little tendency for the vehicle to rock in shifting currents.
The Nova Ray ROV has had seven patents for utility and design issued by the US and Canadian patent offices.

“A good scientist is a person with original ideas. A good engineer is a person who makes a design that works with as few original ideas as possible. There are no prima donnas in engineering.”
—Freeman Dyson (b. 1923)
“Different persons growing up in the same language are like different bushes trimmed and trained to take the shape of identical elephants. The anatomical details of twigs and branches will fulfill the elephantine form differently from bush to bush, but the overall outward results are alike.”
—Willard Van Orman Quine (b. 1908)
