Yes, but does that account for a loose nut behind the wheel?
In my case anyway....
I do not think that locking the thread serves a purpose at this time. Boulderjohns post is indeed excellent, but this thread is important to the dive industry. It asks a tremendous number of questions that will be answered here in court, it asks what duty does one diver have to another, and this is a question in contention here. I am told that Mr. Sotis was along for the ride, that Mrs. Sotis was along for the ride, and that there were no safety divers designated. Now, Mr. Sotis was Mr. Stewart's instructor, but this wasn't an instructional dive. There is some question as to whether Mr. Stewart was even certified to the depth dived.
The Chairman earlier stated (in the Missing Rob Stewart thread) that he believed that Mr. Sotis owed a duty of care to Mr. Stewart. If they were merely buddies, does that still hold? Do all buddy teams owe a duty of care to each other? So far the law holds that they do not, that we are all solo at the end of the day.
And does the boat really owe a duty to a diver? When is a diver a passenger? What qualifications does a boat crewmember have to have to be a deckhand? Does that change for the type of diving? Does a technical diving captain need any certifications other than his Captain's license? Are our divemasters properly trained to be deckhands, or are they someone with the right certification picked up at the dock in the morning? By all accounts, this crew in this situation was trained, I'm not trying to cast aspersions, but a LOT of American liveaboard deckhands are NOT divemasters. and a lot of day boat divemasters are NOT deckhands.
I can tell you that the coast guard has a working group to look at further regulating dive boats. We have not met yet. I will also tell you that the DAN tried to get a class for dive boat owners going to tell them of their responsibilities as far as the Coast Guard goes. Dive boat owners were not receptive. Dive boat insurance companies tell us to just do our best, and give us no further guidance.
I think this is going to be a big deal to the dive industry, at least in the USA. I would not like to see this discussion closed.
