Lotsa luck!!! I have sailed on Princess, NCL, Crystal, RCCL, Celebrity, and Cunard and NONE of them have any topless or nude sunbathing areas. (At least not for the passengers - some of the private, crew-only areas are topless.) Since I too like the sun on my whole body, on certain ships I do go topless, HOWEVER, I follow certain etiquette...I find an isolated spot (usually on the highest deck, as far forward as possible) and get out there early in the morning. I leave my top off all day, or until there are a lot of other passengers around (like going through the Panama Canal, when everyone wants to be at the front of the ship). Also, if there are kids around, I cover up - or move. I've never been bothered by anyone if I follow these courtesies. (If I'm on a ship that I'm not familiar with, I usually ask one of the deck stewards if topless sunbathing on the top deck is OK - they've always said yes.)

FYI...most beach ports (even their "private islands") have a topless/nude beach. You have do a little research to find out where it is - check guidebooks like Lonely Planet or those geared to younger travelers (or ask a friendly crew member).

John, I think RCCL's new ship Voyager is going to have a topless sun bathing spot way up on one of the top decks. It's advertised as a "sunbathing area" and is kinda cut off from other areas. I'm not 100% sure of this but you may want to check it out. Hope this info is correct!
Happy sailing.

John, If you do get any info on this let the rest of us "sunbathers" know!! Thanks!

The Carnival ship "Jubilee" had a nude sunbathing section. Not sure if any of their other ships do.

All Carnival cruiseships have a
topless optional sundeck, located
around the funnel.
