Merchant vessel of the New Crobuzon, inspired by the book The Scar by China Miéville.
In the cargo holds are Remade, basically slaves for colonies over the ocean.
This rusty peculiar vessel uses a special type of propulsion, consisting of sails and magic device on ships beam which displaces air in front of the ship, sails have a unique coating on the surface and are attracted to the air in front. There is also standard steam engine with a propeller. That's at least my poor understanding of it as described by one sailor back in the port.
I want later to include the ship in some enviros based on the description in the book.
