Under the Nine Suns - Cloud Cruiser

Cloud cruisers are flying vessels that can cross the airy expanse known as the Sea
of Clouds. Modern cloud cruisers have a hull, sails and propellers.

The hulls of cloud cruisers appear much like a water going ship, with a long body and keel, designed to cut through the air. Many older cloud cruisers are constructed of wood, though newer, more expensive models use lightweight metals
and ceramics. This is especially true of ships designed for combat. Most cloud
cruisers have an open deck on top, though some warships forego a top deck, preferring to be fully enclosed.

Cloud Cruisers use sails for guidance. Most models keep their sails in long rows along the sides of the ship. Ship crews tilt and furl these sails to change the ship's direction. Propellers on the rear of most ships provide additional thrust, though any good captain appreciates a tail wind. Skydrivers are placed along the hulls of cloud cruisers, often in rows, and allow the ships to fly.

Onboard power is usually provided by a central alch boiler. This boiler turns the propeller and powers the skydrivers as well as providing light and heat to the ship's crew.

There is vast variety in the types of ships that set sail in the Sea of Clouds. Ships designed for pleasure cruises, merchants, pirates, explorers and more all sail the Sea of Clouds together.
