They created a big, naked beauty pageant for nudist girls to compete for the title of Miss Nude World.

Their nudist beauty pageant was held yearly, for 5 years, from 1970 - 1975.
It was so successful, they inspired other nudist clubs to establish similar nude beauty pageants of their own. Cypress Cove was one. And they even sent their own pageant winner to compete for the title of Miss Nude World.

Though Miss Nude World was the first naturist beauty pageant to garner nationwide media interest, it wasn't the first naked beauty pageant held by and for nudists.
In a novel called Fighting Bodies and Country in Canadian History, writers Patrizia Gentile and Jane Nicholas have a brief chapter on naturist beauty pageants and how they fit into the Canadian naturist movement.
According to this publication, some clubs had started hosting "royalty pageants" in the 1960's. Both men and girls participated and the winners were elected / crowned as "king" and "queen." The contestants were judged on their all-over suntan (showed their commitment to naturism), personality, contribution to naturism and their physical embodiment of well-being or attractiveness.
Though these occasions are not open to the public, they still received media interest.
The Miss Nude World pageant resembled traditional beauty pageants in many ways. All contestants were women between the ages of 18 and 30. They were required to be a member of a naturist club, though not for any specific amount of time (One could join a club two days earlier and still qualify).
Instead of being judged by other naturists, the judges were "local community members and minor stars, including company owners and members of the media."
As mentioned in the Naked Hiking podcast, below is a movie clip In The Naked Peacock, which covers somewhat of the 1975 competition. While the spectators were a mix of bare and clothed, women and men, one can not help but notice all the dressed, white man photographers and judges.
Contestants not only modeled nude, but in evening gowns and swimsuits as well (how was this "naturism" at all?).
Physical appearance was a principal component and could earn a contestant the most points. Nonetheless "natural make up" was okay.
The other criteria were based on poise and style. For the latter, each girl had a private interview with the judges.
In the united states, royalty / suntan / beauty pageants were being held at naturist clubs and resorts during the 1950's, if not earlier. It must be in a history book somewhere, but I'm uncertain what year they began or finished in this nation.
Some of the pageants were organized by the membership / leaders of clubs. Others were formed by the American Sunbathing Association's (which will be today called AANR) regional groups.

Like the royals pageants in Canada, these contests were more of an internal event with club members as participants and spectators. They looked far more naive than what went on at The Four Seasons. Miss Nude World took nudist pageants to entire new level and definitely spurred on the trend throughout Canada and the U.S.
There's no question that the beauty pageant goes against naturist values. A contest like Miss Nude World is sexist, exploitative and sexually objectifies women. It places a girl's value in her appearance and judges her based on how she meets society's attractiveness "ideal" standards. In Miss Nude World, those standards were rigorously applied with the "natural beauty" requirements. All of this absolutely negates the idea of body acceptance in naturism and the theory of judging people by their character - not their look!
In fact, in the podcast interview, Hans and Lisa Stein recognize their pageant gimmick was anti-naturism. They were naturists for ten years before starting the pageant and they knew that naturism was not assumed to be about worshiping some kind of beauty ideal. They made millions of dollars in gains and obtained new members after beginning the naturist beauty pageants.
