Airship

This spell must be cast under a cloudy sky. A cloud you indicate descends toward you and transforms into a vessel with the aesthetics of your choosing and the statistics of a longship. Although the ship is made of cloud, it is solid and can support the weight of up to 20 passengers of medium size (or 10 Large, 5 huge, etc.) and one ton of additional cargo in a small cargo hold. It has no need for crew. 

The ship flies with a speed of 50 miles per hour (movement rate of 440 feet) under your control, and can hover. At full speed, it can only turn 15 degrees for every 200 feet it travels forward. Regardless of speed, creatures onboard only experience normal winds. While directing the ship’s movement, you can take other actions but cannot cast spells or maintain concentration on a spell. If the ship is overloaded, it cannot maneuver and descends to the ground at 100 feet per round until it reaches the ground.

If you cast this spell again while another airship under your control exists, it does not create another ship. Instead, the original’s duration is increased by 24 hours. If you cast this spell as a ritual, only a two-person air-boat that can carry a maximum of 500 pounds is created.
