a width of 11.40m and is capable of accommodating 202 passengers. The vessel is powered by four Volvo-Penta diesel engines type D 12-450 MH(KC), with an output of 331kW at 1800rpm. The engines are equipped with
electronically controlled injection pumps and an electronic engine management system. Due to special charging the engines feature a high reserve or torque, making them more suitable for the propulsion of rudder propellers. The vessel has Schottel STP 200 three-blade double propellers, for propulsion. Two elastically mounted Volvo-Penta
three-phase power supply units are installed, each having an output of approx. 525kVA at 1500rpm. Fully automated parallel operation of the units is implemented by electrical
