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.
Occurrence
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 the 25th most common still life on Adam P. Goucher's Catagolue, being less common than trans-boat with tail but more common than hat. It is the most common still life with 11 cells, being 15 times as common as elevener.[2]
One way for them to appear is when a pre-ship-tie has one of its cells prevented from forming, as shown below:

Glider synthesis
- Main article: Glider synthesis
All strict still lifes with a population of 23 or fewer cells, all oscillators with 16 or fewer cells, and all spaceships with 35 or fewer cells are known to be glider-constructible. A glider synthesis of this object can be found in the infobox to the right.
