The Flying Dutchman?

Just arrived in the treacherous waters of Sea of Thieves on Christmas Day. A hearty "Ahoy there matey!" to you all. I collected my Gilded Voyage mission in the tavern and set sail in search of riches galore. I was not disappointed. However, as I was sailing back to port with my glorious haul I was attacked and scuppered by a ghostly vessel which emerged from the depths of the ocean like The Flying Dutchman and hammered my vessel without mercy, sending her, and my hard earned treasure, to the depths of Davey Jones' Locker. I have one question; is this a NPC vessel or was I sorely mistreated by a crew of scurvy dogs?
