If you get sea sick just from stepping foot on a boat, this may not be for you. Not only will you deal with the waves, but you’ll be doing so while headbanging on a stomach full of booze. This is the Full Metal Cruise. The cruise, which recently set sail from Hamburg, Germany, is packed with a few thousand dudes clad in black rocking out to 20 different bands. On board there’s also metal karaoke, metal workshops, and movie nights at sea. We’re guessing their not showing The Notebook.
