- For the class of patterns sometimes called ships, see spaceship.
Adding one cell to the corner of the ship will turn it into a fleet. Removing one of the corner cells results in a boat, while removing both results in a tub. Like the tub and the boat, it is infinitely extensible (see long ship).
Ship is the fifth most common still life on Adam P. Goucher's Catagolue, being less common than boat but more common than tub. Among all still lifes with 6 cells, it is the second most common, being less common than beehive but more common than barge. It is also the seventh most common object on Catagolue, and the most common object for which there is no 2-glider synthesis.
The ship is about 4.5 times as common in Catagolue than in Achim Flammenkamp's census; it is more common than the tub and the pond in the former but not the latter. The reason for this huge discrepancy is because Catagolue's soups are 16×16 with empty space surrounding it, and a Herschel leaving the active region and going into the empty space produces a ship. In comparison, Achim Flammenkamp's census is on a large torus, which is effectively an infinite region, so there is no empty space for a Herschel to complete its sequence, and it is likely to crash into something first.
As mentioned previously, the ship is a notable component of Herschel (and, by extension, B-heptomino) ash, along with two escaping gliders and some blocks.
In other rules
Ship can be infinitely extended, as illustrated by the following:
|No corners (barges)||(^-2) • (^-1) • ^0 • ^1 • ^2 • ^3|
|One corner (boats)||(^-2) • (^-1) • ^0 • ^1 • ^2 • ^3|
|Two corners (ships)||(^-1) • ^0 • ^1 • ^2 • ^3|
