Maybe not so crazy. Until the fire happened, Truth Aquatics had a stellar reputation. If I had a booked passage on one of the other 2 boats and they were still running I would keep it. No question this was a complete fuck up and should never have happened but it was an aberration.
Based on their reputation earned over many trips, I expect them to be smart enough to take preventive steps on their own, to rectify the battery charging set up especially since the source of the fire is pretty much of a given as well as religiously ensure that the crew maintains a roving night watch. As a passenger, I’d probably still sleep with one eye open and cat nap on deck whenever I could but that’s just me.
Newbie divers and landlubbers might be harder to convince.
