You bring up some good points. I dislike the suit happy people as a rule
. I think it's the height of bad manners to sue your host. From my one course in business law, I'd argue that by creating a couple of rules, you might be giving participants a false sense of security
or an expectation of event safety
and thus even open yourself up further to lawsuit. Sadly, if someone wants to sue, they will, but really, what rule
could they have misunderstood? I suppose there's the swimming pool/tree house fence laws because uninvited minors are tempted to break trespassing laws, but I've always thought those were pretty crappy laws. I think by limiting the age, the organizers should be protected from the "enticement" stuff.
The people who underestimate the sea will continue to do so, with or without this event. I'd take a wild guess that people participating in this event will generally look out for each other. There might be a few gung ho types who will probably want to win at all costs, but I don't get the impression that winning is the real point of this event.
