In line with that mindset, Tiemann is helping lead a charge with these cruises against the way nudity is perceived in the United States -- where, for many people, nakedness instantly means sex.
"The way our society looks at nudity, it has to be objectifying," she said. "I think that's changing a little bit, but we haven't done our work well enough yet."
For now, though, the nudist community continues to live an under-the-radar, carefree, clothes-free lifestyle.
"Nudists are the happiest people on the planet!" Morton said. "I've been to $1,500-a-night hotels, and those are the people you might think are really loving life. Nope. It's nudists. They are smiley in the elevator and in the lunch line for noodle bowls. They don't complain. They're a group of folks who don't often get the chance to be together, and they just seem so grateful. It's a refreshing attitude to be around."
