Plain Facts Dept:
You like sailing; I like sailing. The networks? Not so much. To them, the sport is more mind numbing than watching paint dry. Further, covering a sailing event in a visually interesting way (choppers, POV cams, etc) takes time and money - things the networks believe aren't justified by a substantial enough audience.
Televised sports must feature action, violence, and a good measure of easily recognized winners & losers. Sailing accomodates little or none of that, deficiencies certain to lose networks sponsorship money.
As of now, only three days of next year's America' Cup will be covered by NBC. Don't know about ESPN or the others though.
Okay, back to more positive things - like going sailing.
Oh - and: YMMV
