Two men were rescued at Ocean Beach today after a boat capsized, but one person is still missing, officials say. The U.S. Coast Guard received an emergency call at 2:15 p.m. after a 20-foot single-sail boat capsized in the ocean spitting three people into the chilling water.

According to the SF Fire Department, the rescued men suffered from hypothermia and were transported into UC hospital but released in a good condition.

The search team was called off shortly after sunset because “it is too dark,” the fire department says, but it will resume their rescue efforts in the morning.
