That could be bad news. IIRC from other threads, waivers don't release the provider from 'gross negligence,' so they're full protection, anyway. The nature of recreational scuba boat diving is that there is always risk, and the customer needs to accept assuming that risk as a condition of participating in the activity. Gear or a loose tank could fall and break your foot. You could stumble over something on the deck and hurt yourself. The boat might jerk up or down with a swell when you grab the ladder and injure your should (a guy diving out of North Carolina got a broke arm being too close to the boat, though ladder wasn't involved).
You're not forced to exchange your rights for services, as the services are non-essential and you're not forced to obtain them. The issue is not so much your actual rights as what a liability lawyer can convince a jury they are in the shadow of a tragedy. That some juries may be willing to find a known innocent party guilty just to hook the plaintiff up with money adds to the problem.
As a practical example, there are divers who, knowing about the Conception accident and deaths, would still go out on overnight live-board trips on a boat like it. Let them have their informed choice as a matter of free will.
Making everybody a target for lawsuits doesn't make everyone safe, it puts everyone in danger, and businesses hedge their risks by buying larger insurance policies and passing their costs on to us.
