A white circle appeared off starboard bow, resembling a ship's running light.
Distance at sea from a sailboat at night is imperceptible, so fearing collision with a larger ship, I came off the wind to slow speed.
The orb, not as large as the Moon, would appear and shot dead across the dimly lit horizon, toward the starboard quarter in a split second.
There was no trajectory nor trail of flames like a rocket.
It simply passed at an incredible speed.
No one to whom I've spoken had any explanation for this observation.
At the time, my family, 2 crew members & I were enroute to Hawaii from Newport Beach, CA.
It was my shift at the helm, so I was the only person top side.
Would really like to know what type of sighting I witnessed.
No sound was emitted from the bright, white object.
