@Butrflynet,
Thanks for that data, Butrflynet.
I have mixed feelings re this adventure of hers. My primary one is along the lines of 'that spoiled brat'.. but secondarily, I have known a few explorers, one a major early days deep sea diver who helped invent major diving equipment, and one a very serious mountain climber and explorer.. and he started young. And I have ordinary everyday friends who have done a lot of solo sailing, usually racing.
So, what bothers me? I think it's the need to be first (or youngest) and famous. Admittedly, that is her family environment.
