A luxury yacht loaded with ammunition and fireworks sank after catching fire at a California marina, prompting a significant environmental cleanup effort.

The incident occurred on Thursday night at Marina del Rey, involving a 100-foot-long vessel, which was fully engulfed in flames before eventually sinking.

The Los Angeles County Fire Department reported that two individuals aboard the yacht managed to escape unharmed before the fire spread.

The department later confirmed that the yacht had approximately 1,000 rounds of unspent ammunition and fireworks onboard at the time of the fire.

Video footage captured by onlookers showed firefighters attempting to douse the flames, which consumed multiple decks of the boat.

“I saw it fully engulfed in flames and like many of us living here, heard an explosion and saw fireworks coming off it, and more flames,” local resident Lynn Rose told NBC Los Angeles. “Then I walked down here and captured video of it.”

The yacht, identified as The Admiral by Boat International, was last listed for sale in 2018 for nearly $1 million.

The luxury vessel featured four cabins, each with flatscreen televisions and en suite facilities.

Despite the efforts of the fire department, the yacht was completely destroyed and sank at the harbor located at 2201 Basin A.

Following the fire, the United States Coast Guard (USCG) responded quickly to prevent environmental damage from nearly 4,000 gallons of diesel fuel leaking from the sunken yacht.

On Friday morning, USCG crews installed approximately 2,000 feet of boom around the yacht and affected areas of the harbor to contain the fuel spill.

“Our Coast Guard team was able to transition quickly from a fire response to an oil spill response, which allowed us to ensure we had the right people and resources mobilized,” said Capt. Stacey L. Crecy, the Coast Guard’s federal on-scene coordinator. “We were able to deploy containment and collection equipment as soon as it was safe to do so to mitigate the impacts from the discharge of diesel from the vessel after it became submerged.”

The Coast Guard collaborated with several other agencies, including the California Department of Fish and Wildlife, Patriot Environmental Services, Clean Harbors organization, the Los Angeles County Sheriff’s Department, and the Oiled Wildlife Care Network, to monitor and clean up the area.

Crews will continue to monitor the site until the cleanup operation is complete.

The Department of Fish and Wildlife issued a statement Friday morning confirming that no wildlife had been affected by the spill, and there were no reported impacts on sensitive environmental areas.

While the fuel spill is not currently a threat to public health, officials said the cleanup process could take several days.

The cause of the fire remains under investigation, and authorities have not yet determined when the sunken yacht will be removed from the harbor.
