Petty Officer Henry Dunphy says officials received a mayday call from the 62-foot vessel Sea Adventure II at about 1:20 a.m. Friday.
Coast Guard and San Diego harbor police went to the area near South Coronado Island and rescued the people aboard. Four crew members aided by the Coast Guard used pumps to keep the vessel afloat and get it back to port.
Phil Lobred, owner of HM Landing where the boat is docked, says the vessel hit a rock, which put a bowling ball-size hole in the hull.
Calls to Sea Adventure 80 Sportfishing Co., which operates the boat, were not immediately returned.
