Driving our boat and on our way back from

Driving our boat and on our way back from Bahamas,  at 9:35pm March 1st an orb I watched for 5 minutes started in the clouds and steadily lowered and came down to just 100’ over our boat.  The light got so bright that it lit the water all around our boat. Within 10 seconds it looked like it took off but I still don’t know if the light just dimmed out or if it actually sped away.
