The 13-engine Cordership is a diagonal spaceship that was discovered by Dean Hickerson in April 1991. It was the first known Cordership and was the only known Cordership until the discovery of the 10-engine Cordership. Corderships that use as few as 2 engines are now known.

It was also the first non-monotonic spaceship to be discovered.
