SYDNEY (AP) — Two sailors on separate boats have died in boom accidents two hours apart on a storm-ravaged first night of the annual Sydney to Hobart race, adding to the event’s long history of deaths at sea.

The Cruising Yacht Club of Australia in Sydney, which administers the yacht race, said Friday that one sailor each on entrants Flying Fish Arctos and Bowline were killed after being struck by the boom, a large horizontal pole at the bottom of the sail.

New South Wales Police Superintendent Joe McNulty identified the two dead sailors as a 55-year-old man from Western Australia (on Flying Fish Arctos) and a 65-year-old man from South Australia (on Bowline).

He said the crews on both boats, which had been seized by police for evidence, were “doing it pretty tough at the moment.”
