shipboard-directions

Since gravity (there is no such thing as electro-gravity or artificial gravity) is generate aboard ship either via angular momentum while docked at a spacestation or by acceleration, the “front” or bow of the ship is also the top of the ship. This created a need for a different set of directions when aboard a ship.

Superior is the up direction — toward the bow.
