Although the exact factors that caused the fire still remain unknown, the LA times reported that a charging station for personal electronics in the berthing area may have been the source of ignition; Yet, this is an assumption until the investigation reach to an end. Therefore, the NTSB stated that they will examine this scenario.
Jennifer Homendy held a press conference, updating the reporters on the matter, and noted that 'We are not ruling out any possible ignition sources'.

Ken Kurtis, dive trip organiser, the owner of California charterer Reef Seekers Dive Company, stated to Fox News that there is a possibility that the charging station was an ignition source.
Concluding, only five people are known to have survived, including the boat’s captain and four crew members, who were on deck and escaped on an inflatable boat.
