I have to admit, when I think of a cruise, I imagine hanging out on the top deck of a ship in my bathing suit and only interrupting my serial intake of pink cocktails with occasional trips to local markets to buy bags made of straw. That’s the traditional cruise, but of course, there are so many other types of cruises than just that, from corporate conventions on the high seas to floating music festivals. Here are seven of the absolutely weirdest ones I’ve come across.

Oakland Raider Cruise

I’m sorry, but you’d have to be a pretty hardcore fan of the American football team, the Oakland Raiders, to take this cruise, which is entirely themed around the team. The weeklong cruise departs from Los Angeles, opening with a cocktail party and featuring meet-and-greets with Raider Hall of Fame players, concerts, comedy showcases and chances to win Raider memorabilia.

Thunder in the Tropics

This white-trash-alicious motorcycle cruise seems to incorporate everything except, well, motorcycles. Essentially an excuse to round up a bunch of bearded bikers and stick ‘em on a ship for several days, the cruise holds a lottery that only allows 30 bikers to actually bring their hogs on board. Ummmm… What you do get as part of the cruise is the chance to show off your breasts or beards (whichever you have) in a series of contest

s, strut your stuff in the belly flop competition and hoot on the mud wrestling competition while stuffing your face with ribs, wings and gut-wrenching lagers from the all-you-can-stand buffet. Website

Supernatural Cruise

If you love a good mystery, you can take a cruise that explores ghosts, goblins and other spooky stuff. These cruises go all over the world, from the haunted castles of Europe to ghost hunting in Key West. What I can’t figure out is why anyone would wanted to get on a haunted cruise ship bound for the Bermunda Triangle… Website

Chess Moves 4

Could there be anything more dull than a week of doing nothing but playing, talking about and studying chess? I don’t think so, but apparently a lot of people think this is a good idea. So much so that there are entire cruises dedicated to nothing but chess. So, if you’re looking for an opportunity to catch up on your sleep, this might be just the thing. Website

CruiseTrek

As disgusting as this idea is, is anyone really surprised? For as long as there has been Star Trek (so, what, 40 years?), there have been Trekkies and Trek Conventions. These folks have just taken it one step further by hosting their convention aboard a ship, where no one can escape! The CruiseTrek is about what you’d expect: a whole lotta geeks wearing freaky costumes and drinking non-alcoholic foo-foo cocktails. But a word of advice: if you plan to hit the pool deck, be sure to wear some heavy duty sunglasses because there are sure to be some bleach white legs afield. Website

Scrappin’ and Stampin’ Scrapbooking Cruise

Hey housewives, here’s a chance to do exactly what you do at home, but with the added challenge of seasickness! This cruise seems to be exactly what its name suggests: 5 nights of scrapbooking through Bermuda. What do you suppose the ratio of bikinis to glue sticks is on this baby? Website

Twilight Fans Cruise

Vampire porn cruise? Where do I sign up! Okay, I admit I don’t actually know who Jodelle Ferland, Alex Meraz and Michael Welch are, but I presume if you are a Twilight fan, these names mean something and are enticing enough to spend hundreds of dollars for a few nights to hang out with them. Website
