HSC Express 4

Express 4 is a high speed catamaran built by Austal for Molslinjen.

History
Molslinjen ordered Express 4 in June 2016, at a cost of about A$100 million. In April 2017, construction began at Austal's Henderson shipyard with the ceremonial first aluminum cutting. In August 2018, the ship was launched, with fitting out and sea trials scheduled to be completed by the end of the year ahead of entry into service in early 2019.

Express 4 left the construction hall on 27 August 2018 and was launched in October. Since being delivered, she has operated between Aarhus and Odden, Denmark.

Design
Express 4 measures 109 m long, with a beam of 30.5 m and a draft of 3.4 m. She can carry up to 1,006 passengers and 22 crew, and has two vehicle decks with space for 425 cars and an additional 610 lane meters for freight vehicles. She is powered by four 20-cylinder MAN engines producing 9,100kw at 1,000rpm that drive 4 Wartsila Waterjets via a reduction gearbox, giving her a service speed of 40 kn and a maximum speed of 47.8 kn.
