I'm not blaming anyone at all, just saying that the layout was pretty standard for a dive boat. The fire could have been started by a guest charging a ton of lithium batteries for camera gear for all we know. Regardless of the cause, tragic and sad for everyone who perished and their families.
35 people for a boat this size. ToI am surprised people are willing to pay to be packed like sardines, no more over rated experience than sleeping at sea, depending on conditions and vessel of course.
