Former Baywatch and Knight Rider actor David Hasselhoff will be captaining the third edition of It's The Ship, one of South-east Asia's biggest dance music festivals, which is held on a sea vessel.

But the captain will not be taking to the decks on board the Royal Caribbean international cruiseliner. He will only be making announcements on the ship, hosting a gala dinner night and appearing throughout the vessel at various activities.

This year's headlining acts on the booze cruise include Australian electronic dance music act Knife Party, Moldovan producer and DJ Andrew Rayel and Swedish duo Dada Life.

Held over four days and three nights from Nov 4 to 7, the event will feature more than 60 acts at multiple stages across the ship.

The port of call for the party ship this year will be in Penang.

It's The Ship will take place on a 15-deck cruise liner, one of the world's largest, which features a casino, a rock climbing wall that overlooks the sea, a full sized basketball court, an iceskating rink, a mini golf course, a duty-free shopping promenade and 17 bars, clubs and lounges.

Last year's edition, which saw the likes of Kaskade, Showtek and Ferry Corsten headlining it, was a sold-out affair with more than 3,800 fans from 50 countries in attendance.

Tickets for It's The Ship went on sale in March via www.itstheship.com. Cabins are priced between US$588 (S$794, excluding taxes and fees) a person, for a four-person interior cabin, and US$5,888, for a two-person royal suite with balcony cabin.
