The Worldchampion Jet (former Villum Clausen) is a fast passenger ferry built in 2000 by Austal, Perth, Australia.

On 19 December 2017, HSC Villum Clausen was sold to the Greek based Ferry Company Seajets.

In 2000, it broke the world record for the longest distance travelled by a commercial passenger vessel in 24 hours.

[3] Worldchampion Jet operates daily from Piraeus to Cyclades: On the way from the shipyard of Austral's shipyard in Henderson, Western Australia to Rønne, Denmark, the ferry had a top speed of 47.7 knots (88.3 km/h; 54.9 mph) and an average of 43.4 knots (80.4 km/h; 49.9 mph), and on February 16 and 17, 2000 it had reached 1063 sea miles within 24 hours, thereby setting the world record which was then recorded[citation needed] in the Guinness World Records.

[3] The record lasted for 13 years until the HSC Francisco broke it in 2013, a 99 metre ferry with a top speed of 58 knots.
