Abstract
An air direction device is submerged under a dry dock. The device imitates the orientation of the dry dock and is in communication with an air source, which pipes air under the device. The air travels to the most elevated portion of the device, which in turn directs the air into a depressed tank to correct dry dock imbalance.
