The Sassy Lass --good for a crew of female pirates...
Wretched Excess --okay, so that sounds more like a Culture starship...
Grim Fandango --helps if Fandango's are actually some kind of monter in the setting...
Hot Cross Guns --only if gunpowder's available... and the pirate's are Catholic...
If I Stop Moving, I Die --definitely a Culture ship...
The Ancient Marinator --good if the captian a cocktail-swilling alcoholic...
The Windlast --good for slow-moving pirate ships.
The Hardy Martyr --that's actaully kinda cool...
