How a crew of vampirates conducts itself depends entirely on the mood and disposition of the captain.
The crew of one ship might behave like a murderous mob, while another might abide by an ancient code of chivalry.
One captain might allow the crew of a plundered ship to live, while another might leave only flotsam and jetsam in the pirates’ wake.
The captain is often accompanied by an undying companion, such as a crawling claw or a will-o’-wisp.

Ship Invisibility (Recharges after a Short or Long Rest): A ship upon which the captain stands, along with all creatures and objects aboard it, becomes invisible to creatures not aboard the ship.
The captain must concentrate on this magical effect to maintain it (as if concentrating on a spell), and it lasts for up to 1 hour.
The effect ends if the captain leaves the ship.
Uncanny Dodge: The captain halves the damage that it takes from an attack that hits it. The captain must be able to see the attacker.
