This incident has parallels to the supposedly experienced climbers lost this past winter on Mt, Hood. One of the talking head cable shows had an interesting debate between a spokesperson for the National Geographic Society (who advocated for the "everyone has the right to test his/her limits, even to the point of death" position) and another advocate who said that access to such sites should be more closely monitored for weather, training of the climbers, etc.
The second person made a good point in saying that such weekend adventurers do not have the "right" to risk their lives because it wasn't only their lives they risked, but also those that had to come after them.
Also, before doing a dive at the limits of our experience, we should consider the impact an accident will have, not only on the family and friends, but on the boat and crew that have to witness events, deal with the outcome and live with the consequences of your "right" to kill yourself.
We have discussed obligations of the charter boats to the divers, but what about divers to the charter boats? Is it fair to them to embark on something extreme without their knowledge? This particular dive sounds like a techical dive, but another poster said that charters like scuba-do don't take out techical divers? Something doesn't make sense in that regard. The boat has a right to know what a diver is up to, if it exceeds the scope of the chartered trip.
