SAN DIEGO -- Lifeguards rescued 16 people after their boat ran aground in Mission Beach Friday morning.
The boat crashed ashore near San Fernando place, just south of Belmont Park, around 5 a.m., according to San Diego Police.
The 65-foot-long motor vessel named "Pacifica" was headed back from a fishing trip in Mexico and scheduled to dock at 6 a.m., Lieutenant Rich Stropky of the San Diego Fire-Rescue Department said. "We don’t know how it happened or what happened, but that will be thoroughly investigated," Stropky said.
The Coast Guard is leading the investigation.
Lifeguards said despite a challenging tide, 16 people were rescued by rope and four crew members remained on the boat. No injuries were reported. Members of San Diego Fire-Rescue were there to assist.
“It went smooth but it was a little overwhelming for the lifeguards in the beginning, just not knowing who was doing what and getting units on scene," Stropky told FOX 5.
With help from a tugboat and the rising tide, the boat was moved off the shore by about 6:30 a.m.
The "Pacifica" was floated about three nautical miles away to a shipyard in Mission Bay, a Coast Guard official said.
The Coast Guard did not release the names of the people onboard.
