Boat with long tail is a 10-cell strict still life.

This still life is comprised of the normally stable boat with a normally unstable long tail attached.

It can be substitutively referred to as the shillelagh with boat, with the pre-block of the shillelagh replaced with a boat, however "boat with long tail" is usually preferred for this object.


Boat with long tail is the sixty-fourth most common still life in Achim Flammenkamp's census, being less common than trans-bun and wing but more common than cis-bookend and bun.[1]

It is the 62nd most common still life on Adam P. Goucher's Catagolue, being less common than very long snake but more common than long shillelagh. It is the 9th most common still life with 10 cells, being less common than broken snake but more common than long integral.[2]

Glider synthesis

All strict still lifes with a population of 21 or fewer cells, all oscillators with 16 or fewer cells, and all spaceships with 31 or fewer cells are known to be glider-constructible. A glider synthesis of this object can be found in the infobox to the right.
