The doomed Santa Cruz dive boat appeared to be well-equipped for fire emergencies, deepening the mystery of how it turned into a deathbed for 34 sleeping passengers.

“Of all the boat companies, that would be one of the ones I wouldn’t think this would happen to,” said regular passenger Dave Reid, who said the vessel, Conception, had a reputation as being one of the safest boats.

The 75-foot dive boat had fire extinguishers and smoke alarms in the bunk area, former passengers told the Los Angeles Times. They also praised the crew for how well they have prepped passengers over safety precautions ahead of previous trips.

“They tell you where the life jackets are, how to put them on … the exits, where the fire extinguishers are, on every single trip,” said regular passenger Terry Schuller. “They are the best, the absolute best.”

In addition to a curving staircase leading from the bow end of the bunk room to the galley area, there was an escape hatch above one of the bunks that led to the deck and galley, the paper said.

“All you have to do is get up to a bunk and keep going up and you use the bunk as ladders,” veteran dive master Bruce Rausch, 69, told the paper of the boat he has been on dozens of times.

While Conception had some safety violations — including for a heat detector that was later replaced and a leaky fire hose — all of them were quickly addressed, according to Coast Guard records.

It had regular inspections, including in February this year, which did not indicate any violations.

Five crew members on deck managed to escape, while 33 passengers and one crew member sleeping below deck are feared dead. As of Tuesday morning, 25 bodies had been found, while nine were missing.

The boat was far from packed, with the 20 single bunks and 13 doubles, stacked three high, able to sleep up to 46 people, according to the LA Times.

Reid called Conception and the rest of the fleet owned by Truth Aquatics “always immaculate.”

“I wouldn’t hesitate at all to go on one again,” he told the Times.

Dive photographer Joe Belanger, however, noted that even the best safety plans may not help when the boat is engulfed in flames off the Southern California coast.

“Finding your way out, though, at 3:30 a.m. when there is no electricity but thick smoke and flames is impossible,” he wrote on Facebook.

Santa Barbara County Sheriff Bill Brown also noted the hazards of a raging fire in the middle of deep waters while passengers were asleep.

“You couldn’t ask for a worst situation,” he said at a press conference Monday.

Investigators are still probing the cause of the fire.
