Unlike other propulsor designers we have our own hydrodynamics research centre, equipped with two cavitation tunnels. In over 40 years of operation the centre has tested around 1,400 propellers and waterjet pumps to perfect and prove the design. Our propellers deliver good fuel economy, low vibration and noise levels and minimal cavitation.
