A 53-year-old North Kohala man has died of injuries suffered when a boat hit him Monday.

James C. Williams, of Hawi, was swimming about 300 yards offshore from Mahukona Beach Park with another man when he was hit by a boat traveling toward Kawaihae about 11:15 a.m., Big Island police said.

He sustained injuries to his shoulder and head and was brought to shore by the boat operator. The fire department had said Williams suffered multiple cuts from the boat’s propeller.

A fire helicopter took him to North Hawaii Community Hospital, where he died at 3:01 p.m. Monday.

The state Department of Land and Natural Resources has jurisdiction of the case and will continue the investigation, police said.
