The words, “young woman,” or “young lady” are euphemisms often used for little girls. I might call a small boy, “young man.” She is a child - Sixteen, so YOUR screed against those who are calling her a child is ludicrous, as that is the proper term.
Second, as to her not being old enough to assess proper risk. Everyone who has “kids,” knows that their judgment of anything is not fully developed. We even have much brain science to back this up. The frontal lobe is not fully developed even when a young person is 18 or 19, let alone 16.
Most people worry about their daughters going away to college, let alone sailing alone across the world - where there are pirates, fish with big teeth, and the elements.
And, let’s not forget the sheer idiocy of sailing in the southern hemisphere during their winter. DUH!!!!!!!!!!!
Thus, I conclude with wondering about the judgment skills of the parents as well. “But she likes to sail!” Oh, brother.
This is true of every human being on earth? Generalizations are the stuff of wimps.
