These bow thrusters are more aerodynamic than the round rotating elbow nozzles older models use.

The 12000TD also features new technology that Griffon has pioneered. Mixed aerodynamic flow fans are used to minimise power taken from thrust for lift and compact permanent magnet generators, motors and an in-house developed power electronics control system is used for the bow thrusters. Development of the latter was a result of work on a new small hovercraft using diesel electric drive, the 995ED, where the electric solution allowed distribution of machinery around the centre of gravity to obviate the need for ballast.
