Captain Monica Rochester, USCG Los Angeles-Long Beach sector commander, told reporters Monday morning that 39 people were on board the 75-foot dive boat, named Conception when a fire engulfed it in the pre-dawn hours.
The 34 people who are still missing were below deck, sleeping, she said.
Five crew members on board were awake on the deck when the fire broke out, and they jumped into the water, Rochester said. They were rescued by a Good Samaritan boat called The Grape Escape.
Rochester said they are still in a response phase, conducting shoreline searches for any possible survivor.
The vessel sank about 20-yards off the coast in 54-feet of water. A portion of the bow is still sticking out of the water.
The cause of the blaze is not clear. Search and rescue efforts are still underway.
The boat set out from Santa Barbara on Saturday for a diving excursion, and was set to return to shore Monday at 5 p.m. local time, according to the website for the diving company, Truth Aquatics.
