The Worldchampion Jet (former Villum Clausen) is a fast passenger ferry built in 2000 by Austal, Perth, Australia. Until 31 August 2018, it was in active service between Rønne (Bornholm in Denmark) and Ystad in Sweden. On 19 December 2017, HSC Villum Clausen was sold to the Greek based Ferry Company Seajets. Starting from the summer of 2019, it was renamed WorldChampion Jet and started sailing between Piraeus and Cyclades.
HSC Villum Clausen was named after the 17th century Danish freedom fighter Villum Clausen (da). In 2000, it broke the world record for the longest distance travelled by a commercial passenger vessel in 24 hours.

However the record did not last as in 2013 Austal's arch rival Incat, the only other shipbuilder producing large fast catamarans, built HSC Francisco, a 99 metre ferry with a top speed of 58 knots. It operates on the route between Buenos Aires and Montevideo.
