The prefered methods would be powder extinguishers or flooding with inert gas (evacuate interior before flooding with inert gas).

The vessel had an automatic fire suppression system in the engine room (where fires generally originate, not sure if it was powder or inert gas) and extinguishers in the galley,the other ignition point for fires aboard a vessel - all up to current Coast Guard standards.

Truth Aquatics suspended all boat operations indefinitely on 1 October.

Somewhat off topic, but I have taken to packing my own fire/CO2 detector along with me whenever I am staying in a hotel. It takes up little room in a suitcase and can be bought for $25-$35 at any big box home improvement store. It just adds an additional level of safety. Most of those hotel detectors are smoke only, and who knows how well they're maintained?

Reports are that this boat had smoke detectors, but someone placing one in the sleeping area could have made a difference.

A sensible precaution, brandtb. I've thought about getting one for home but presently I live in an apt with all electric everything, not much CO2 to worry about except what's in the atmosphere.

It is a very good question ... why didnt the smoke alarms go off in the galley area? Why didnt anyone hear them?

The biggest thing that I have learned ... be very careful with re-charging of Li-ion batteries. It is important to use a proper charger, and not a cheap knockoff. I read the accounts of several people who experienced battery failures in phones (re-charging). It is a violent event. So now i am much more careful where I charge my phone at night.
