Navis Engineering is to supply its JP4000 Joystick Control System to Drettmann Yachts for a 24m Explorer Series vessel under construction at Acico Yachts BV in Enkhuizen in the Netherlands. The yacht features unique electrical podded thrusters in both the stern azimuth and bow tunnels which dramatically reduce sound and vibration and the JP4000, adapted to individual customer requirements, adds greater control and flexibility when maneuvering or with the integrated autopilot at sea.
