In fairness to the kite surfers, they are not students or novices, or seven years old. They have a pretty well rounded experienced team.
Their trip does seems risky to me. But looking at their bio, they have already accomplished feats many here would strongly disapprove of, call crazy, and dig up tales of misadventure and doom.
As far as what the biggest danger
to them is, I'd say a kite surfer being lost
at sea ( I know, my powers of deduction are amazing
Did anyone see their storm plan? What weather
threshold they decided to scrub the kite surfing?
BTB my dad, at 15, was the youngest to climb Grand Teton. Im sure the record
has been broken, it was almost 70 years ago. He went on to climb the highest peak on every content, become a pilot, including gliders, and a circumnavigator. He didn't do all that to break a record
or have bragging rights, he did it because he loved it.
