One man is dead and a woman injured after a late night watercraft accident in The Bronx on Tuesday, officials said.

A 30-year-old man was driving his Jet Ski with a 26-year-old female passenger near Evers Marina and Seaplane Base in Eastchester Bay about 9:20 p.m. when they struck a docked boat, cops said.

They were ejected from the Jet Ski, with the driver sustaining head injuries and the woman suffering a leg injury.

Both were taken to Jacobi Medical Center, where the man was pronounced dead. The woman is in critical but stable condition.

Their relationship is unclear, cops said.

A 31-year-old man who was cleaning or doing maintenance on the boat at the time was not injured, police said.

The cause of the crash is under investigation.
