Long ship is an 8-cell still life discovered by the JHC group in 1970[1] and is a longer version of the ship. Unlike the regular ship, this survives in HighLife.
Commonness
Long ship is the seventeenth most common still life in Achim Flammenkamp's census, being less common than paperclip but more common than shillelagh.[2] It is also the twenty-fourth most common object on Adam P. Goucher's Catagolue.[3]
A long ship can be created when a traffic light predecessor hits a tub. By itself, it does not survive long, but it can survive in a soup if there are nearby active regions.
