Undead Pirates

During the Age of Sail, it was quite fashionable (if you want to call it that) for Resurrectionists or Necromancers to have at their beck and command a crew of Undead Pirates to ferry them across the oceans of the world. These Undead Pirates would also double as a bodyguard and foot soldiers to use in battle. 
The great thing about Undead Pirates is that they require little in the way of provisions (perfect for month-long sailing) and they can't drown either. 
Curiously, you'd think the Order of Corsairs would be incensed about this, but given their cavalier attitude about life they are surprisingly apathetic about the whole idea of having their compatriots brought back from death as servants of the Weird Ones.
