The Crimson Permanent Assurance? I couldn't very well call the pirate ship the Spanish Inquisition, now can I? Everyone's come to expect that by now.
Most likely I'd have to call it "The Good Shepard" so it doesn't sound so piratey, allowing me hearties and meself to avoid the Sea Opies yet advertise our activities fair and honestly, as unseemly as that is for scoundrels of the sea.
A Good Shepard knows how to fleece his flock of sheep and fleeceing is what pirates be doin' best! Y'arr!
Y'arr'd Vark would also do in a pinch.
