Unrelated to the right or wrong of this.
I would love to know how to sail, but I would never attempt what she is attempting at any age. I can't even imagine enjoying myself alone out there for that long. If I was a good sailor or had a girl that was it might be different, even fun.
I love the ocean. I love challenges. I just don't think this is one I ever would have tried.
I still can't fault her or her parents for it. Especially since her brother accomplished it. I am not sexist. If they let him try it, they almost have to let her if she is a qualified sailor, and I see nothing in any article that tells me she isn't.
Tragedy or not, I can't fault anyone for having adventure in their soul. Mine was firefighting at 14 years old. I did it for seven years. I can't know the adventures I have had, and fault another kid for theirs.
