Seeing the world via a ship has become more and more popular. More than 22 million people took a cruise in 2014, according to Cruise Lines International Association, Inc.­­, the official trade organization of the cruise industry of North America.

The majority of cruise ships travel to the Caribbean and include similar amenities – all-you-can-eat buffets, spas, pools and entertainment – but a growing number of themed cruises are competing with traditional cruises.

From booze cruises to maritime murder mysteries, there are special interest themed cruises for just about anyone looking to take to the sea. Check out these weird and wonderful themed cruises and get ready to set sail.
