Project details

The Sankta Maria II ferry is the first fully electric operated car ferry for inland waters in the world. She sails between Wasserbillig and Oberbillig and replaces the previous Sankta Maria ferry. This saves around 14,000 litres of diesel fuel per year. 
The ferry has a hull length of 17 metres and is 8.6 metres wide. The access flaps are each 5.5 metres long. The load capacity is 25 tonnes. The deck is designed for six passenger cars on 2 lanes each 2.5 metres wide, as well as 45 people and 25 bicycles. The transmission is powered by four electrically driven rudder propellers of 27 hp each. The power required for this transmission comes from the drive batteries, which are recharged overnight with shore power (approx. 6 hours charging time). The battery capacity is designed for 13 hours of ferry operation plus a further 13 hours as a safety backup.
