Anyone tired of dressy evenings on cruise ships might be interested in nude cruising, which has grown along with the industry as a whole. The only catch: you may have to go to Europe.

Both Bare Necessities and Castaways Travel are offering cruise departures for 2008. The general policy of the companies is to charter mainstream cruise ships for the trips.

Though Carnival in years past touted topless decks, the practice remains a no-no on most of the major US cruise lines, except for special charters.

Cruisecritic.com editor Carolyn Spencer Brown says cruisers generally need to go to Europe to find such openness.

As for Carnival, no one expects a revival of bottoms-only decks anytime soon.

"The topless decks weren't really utilized all that much," said spokesman Vance Gulliksen, and they "took up some prime real estate."
