Why does she need to travel at all? If she want's to address Congress, or the United Nations, why can't she do it in a studio or venue nearer home and have it screened at the conference, or wherever?

Ocean sailing, no matter how up to date the technology, is not a pursuit for wimps and, even on the calmest days, the swell can be unsettling in a small sea going craft, when you have the kind of wind they want, or even gales - excuse me, the thought of it has me running for a sick bag.
