Luiz, per your comment: "If choosing strictly by Olympic philosophy (best man/woman wins), singlehanding is mandatory."
I'm not aware of any Olympic rule that says anything about all the events needing to be singlehanded. Here are some examples, I'm sure there are many, many others:
2-man bobsled
4-man bobsled
various relay races (running, swimming, etc.)
team events (gymnastics)
figure skating pairs
curling
ice hockey
basketball
I'd say that sailing falls into the bobsled-ish category. Athletes are riding a piece of equipment, there are many forms of the equipment. Some are single-handed, others are teams: luge, several bobsled sizes, and whatever that insane thing is where you go down head-first!
I think it would be cool to see team racing, as that gets advertised as the fastest-growing segment of sailing.
If they are really concerned about raising the number of women, instead of open, they could have co-ed teams in one or more of the classes. Require one person from each team to be male, the other female, like in the pairs skating.
