But which death results in a deader child? Horses are dangerous. They can be the most peaceful companion you will ever have and then on day, getting into a trailer (as they have done a thousand times before) the horse spooks, rears and comes down on your head and your life is changed if not outright ended. Gymnastics is dangerous. Miss a release move and your life is changed forever if not outright ended. Sailing is no different. The risks death are higher for such a journey as this but are they unacceptabley high? In your opinion, yes. In my opinion, no. Your opinion is based solely on what you b believe a person of a certain age is capable of without ever meeting the person. My opinion is based on the potential that a person of a young age can indeed master the risks if properly trained and prepared. You prefer to protect at all costs while I prefer to encourage despite risks being higher than other activities.A fall from a horse won't necessarily result in her dying. She might end up with a concussion, a few bruises, a broken neck (which people can live through) or die. Also, it is much more likely that she will get medical attention immediately of shortly after.
OTOH, if your child is alone on the open sea and her boat is overturned or goes down, unless she can dog paddle or float on her back for hours, weeks, days, etc. without getting eaten by shark, drowning or dying of thirst, her chances of surviving and being found alive are far less than the kid that falls from a horse.
