Motorhead have revealed the first acts signed up for their "Motorboat" cruising festival.
Megadeth, Anthrax, Zakk Wylde, Danko Jones, Fireball Ministry and Wilson will be aboard the luxury vessel "Carnival Ecstasy", which leaves Miami, Florida on September 22 for a four-day voyage.
Motorhead frontman Lemmy says: "This will be everything you've come to expect from a night out with us, except even louder, with more great bands and no way of escaping. If you thought waves could rock a bot, you've got another thing coming with this lovely little outing."
Megadeth's Dave Mustaine adds: "There never has and never will be another cruise like Motorboat. This is the coolest way ever to see a metal concert."
The "Carnival Ecstasy" boasts 12 bars, a 24-hour pizza joint and a resort-style swimming pool. Along with band performances, entertainment will include artist meet-and-greets, Q&A sessions and theme nights.
Tickets for the cruise go on sale on March 18. Find out more.
