Obviously there has to be a line somewhere, which may be blurred by proof of ability depending on the task at hand.
A few hits on Google and you'll find a myriad of "youngest" attempts, such as this one.
www.msn.com/en-au/ stating that she has been taken out of the care of her parents! They are not disputing her abilities as a sailor, but her mental acuity to accomplish the task. So, for the Dutch at least, the line is somewhere OLDER than 13.
tech.mit.edu/V116/N18/pilot.18w.html is the story of the 7 year old Pilot, she wasn't even on her own and had an instructor and her father with her, but the back story is, they were trying to meet media deadlines and took off in bad weather. Something no decent, sensible pilot would ever do..... So, who was being pushed there? For the US the line is probably somewhere OLDER than 7.....
Then there is this
en.wikipedia.org/wiki/Vicki_Van_Meter One wonders whether the coming down from the "high" of all the fame and notariety was perhaps part of the cause of her suicide.....
On the other side of the line, Zac Sunderland (who's sister Abby is currently raising funds for an attempt), Mike Perham and Jesse Martin have all come home safely. However, like Jessica Watson, they all had the benefit of multiple electronics systems to help them steer, navigate, stay in touch and eat correctly. So one wonders whether it's really a "solo" attempt at all.
Francis Chichester -
en.wikipedia.org/wiki/Francis_Chichester started flying at the tender age of 18, trying to break Bert Hinkler's record from London to Sydney - then albeit a lot later, he was the first to circumnavigate the Clipper routes WITHOUT THE AID OF COMPLEX electronics, in a leaky boat and nursing an aging, aching body. If you've never read the stories here's a good start
theopencritic.com/?p=11So, for my money, it's not about the age, it's about the ability, mental preparedness and the dogged determination to succeed. Even in such adverse conditions with failing gear, if you have perseverance and courage it can be done.
One also wonders how any of these kids would go if they needed to navigate by sextant and had no radio communications, blog updates or contact with anyone but Neptune.... my guess is that they'd never actually start the journey at all.
Still, hopefully Jessica and all those who follow in her footsteps will be an inspiration to their generation, just like Chichester, Cottee, Lexcen and even Dick Smith were to my generation.
