Seeing as how successful the 70,000 Tons Of Metal Cruise was last month, it seems like hard rock and metal cruises are an actual trend. After two successful years, Shiprocked has announced their third run, which will sail out from November 14 to 19. The cruise will be heading to Costa Maya and Cozumel, Mexico while bands perform aboard the MSC Poesia luxury cruise. Bands that have already been confirmed to perform at the “rocking” cruise are Buckcherry, Hinder, Hellyeah, Sevendust, In This Moment, Broken Teeth and Rival Sons, with many more expected to be added soon.

As you can already tell, the biggest difference between ShipRocked and 70,000 Tons Of Metal is the type of bands slated to play, with ShipRocked going for more radio friendly hard rockers (at least so far). However, here are some more things we’re speculating will set the cruises apart from each other.

Beer Consumption: 70,000 Tons Of Metal apparently sold a record breaking amount of alcohol for that particular cruise line early on during the voyage. Expect ShipRocked to break that record within its first hour at sea. How else would you be able to enjoy a set from Hinder without a little liquid courage?

Female Audience: From what we’ve seen from pictures, there appeared to have been a nice ratio of men to women aboard the 70,000 Tons Of Metal Cruise (and a lot of them were pretty cute too). However, thanks to Buckcherry, the ShipRocked cruise will probably have more crazy bitches of the two.

Nationality: People from 48 different countries at the event were reportedly aboard the 70,000 Tons Of Metal Cruise . Seeing as how all of the eight bands announced so far are American, expect ShipRocked’s audience to be mainly from North America.

Jacuzzi Action: The jacuzzis aboard the 70,000 Tons Of Metal Cruise apparently saw its fair share of action, though we have a feeling that the ShipRocked’s jacuzzis will be used so often for hot action that you’ll probably want to stay away from it (unless you’re cool with the possibilities of catching a floating STD).

Weight Of Attendees: This is a toss-up. At its worst, we could imagine a lot of overweight midwesterners ponying up cash for a chance to hang out with Hinder and Buckcherry, but we’d also imagine they’ll get their fair share of relatively slim groupies as well. 70,000 Tons of Metal had Dino Cazares though, which might even things out a bit.
