The 42-foot fishing boat found capsized off Silver Strand Boulevard was empty and may have been dragged south from near the entrance to San Diego Bay, officials said.
A Navy ship first spotted the vessel at 11:45 a.m. Friday and notified the U.S. Coast Guard and Coronado Lifeguards.
The city's lifeguards, as well as state lifeguards, and the Coast Guard searched for anyone who may have been aboard the boat. No one was found, and a dinghy normally with the vessel was gone.
Authorities said it was discovered that the boat, whose name or vessel number was not immediately available, had been anchored Thursday off Zuniga Jetty, near the entrance to the bay at Naval Air Station, North Island. They believe heavy winds from Friday's storm may have pushed the boat along with its anchor south to Naval Amphibious Base, Coronado.
It is believed that the person onboard Thursday may have used the dinghy to leave the boat but it is unknown when.
Authorities are trying to track down the person to make sure everyone is safe.
The boat sits in the shore being battered by waves. Debris was found floating early Friday afternoon south toward Silver Strand State Beach and was being picked up. Some oil and fuel leaked into the water.
Coronado Lifeguard Captain Sean Carey said it is up to the boat's owner to retrieve the boat. He did not know when that would happen.
The capsized boat is offshore of Navy property about a half mile south of the border between Naval Amphibious Base and the city.
