Ship-tie (or half fleet) is a 12-bit still life. Its name is derived from boat-tie.

Commonness

Ship-tie is the ninth most common still life in Achim Flammenkamp's census, being less common than long boat but more common than barge.^[1] It is also the twelveth most common object on Adam P. Goucher's Catagolue.^[2] It is the most common object in Catagolue for which there exists no 3-glider synthesis.
