Boat tie ship (or boat-ship-tie) is an 11-cell still life.

As its name implies, it involves a boat having been tied to a ship.

Commonness

Main article: List of common still lifes

Boat tie ship is the twenty-sixth most common still life in Achim Flammenkamp's census, being less common than hat but more common than very long boat.[1] It is also the thirty-first most common object on Adam P. Goucher's Catagolue.[2]

One way for them to appear is when a pre-ship-tie has one of its cells prevented from forming, as shown below:

One generation before a fleet, but one of the cells of a ship-tie is prevented from forming. The two extra cells can come from anywhere and do not have to be sparks. (click above to open LifeViewer)

Glider synthesis

All strict still lifes with a population of 20 or fewer cells, as well as all oscillators and spaceships with 16 or fewer cells, are known to be glider-constructible. A glider synthesis of this object can be found in the infobox to the right.
