A diver was killed this morning at the mouth of the Waianae Boat Harbor after being run over by a 21-foot fishing boat.

The man, described as in his 50s, had a mask and fin and a surfboard when a 21-foot recreational powerboat exiting the harbor ran him over, officials said.

“He was with another person and he was apparently run over by this boat,” said Shayne Enright, spokeswoman for the city’s Department of Emergency Services. “They stopped and rendered aid, along with a couple of people from another boat.”

State Department of Land and Natural Resources officials said the victim is in the Army and stationed at Fort Shafter. He had been staying at the nearby Waianae Rest Camp, according to DLNR.

Enright said an Ocean Safety lieutenant paddled out and helped bring the man to shore, where he was pronounced dead. “It happened right at the harbor entrance,” she said.

The call came in at 7:20 a.m., Enright said.

Police, firefighters, lifeguards and paramedics all responded.

HPD is investigating.
