Good list, Dan. Would love to see your ratings of LoBs, as well.
What I really hope to see (maybe @John Bantin or Ben Davison will undertake a UC survey or include a safety "star" category on the UC review form) is a broad list of LoB's showing safety features. Boat safety is a whole topic that largely goes ignored in dive magazine/diver reviews alike. That's probably because most divers don't worry about things that won't happen. Well....
When picking/researching LoBs I'll: 1) reach out to previous divers who've written reviews in UC and SB and ask questions about safety features/conscienousness (e.g. multiple points of lower deck egress, 24 hour watches, briefings), 2) review deck plans to see if exits are indicated, 3) reach out to the boat itself and ask same, 4) just look at photos to get a sense for whether the thing is a slab sided scow ready to fall over in a stiff breeze. The Conception fire hit close to home and made me realize that I'd been kind of sleep walking on this topic the previous 30 years-I was on Vision during a near miss in 1993. No more, even though I still prefer older wood LoBs over steel.
Once on board I'll check out exit routes, whether the 24 hour watches exist, exit hatches actually open, etc. If I'm up in the middle of the night I'll creep around to see who's up. Like you, I have a water proof go bag hanging on the cabin door.
All this amounts to "doing the best I can" with the information I can get. There's a lot one can learn (informational and attitudinal) from just talking to people if it's a priority.
As far as LOB ratings, I would just state the obvious aspect, boat safety. Nautilus boats are the best in terms of boat safety.
We were participating in their safety drill on the fist day of the voyage. I wish all liveaboards are doing that, as talk is easy. Walk the talk is hard, but that gets you into the groove of safety being at utmost important and you know how to react when sh*t hits the fan.
