Many thanks Nick - I'm in a different jurisdiction outside the U.S. so I'm not totally familiar with the details like dates, legacy and grandfather rules etc - you have provided some good information there.After the Conception fire, the Coast Guard issued additional safety rules for live aboard dive boats operating in US waters. But older boats built before 1996 still aren't required to install fixed fire suppression systems in the engine room; only portable extinguishers are required. Prospective passengers might want to check how old the boat is, and ask the boat operator whether they meet the Coast Guard minimum or have additional fixed fire suppression systems.
One of the issues I see with fitting fire suppression on a liveaboard is that simple systems like a big CO2 dump won't necessarily work in places like the galley, charging stations etc as they aren't enclosed, and stopping lithium battery fires is quite difficult.
