Very long boat (or long2 boat) is the long long extension of the boat, found in 1971.[1] When combined with a block, it can be used as a one-time splitter that turns one glider into three.

Main article: List of common still lifes

Very long boat is the twenty-seventh most common still life in Achim Flammenkamp's census, being less common than boat tie ship but more common than tub with tail.[2]

It is the 28th most common still life on Adam P. Goucher's Catagolue, being less common than very long ship but more common than tub with tail. It is the 4th most common still life with 9 cells, being less common than hat but 10 times as common as cis-boat with tail.[3]

It is the rarest still life with a 3-glider synthesis, although the pentadecathlon is even rarer.

Glider synthesis

All strict still lifes with a population of 21 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.
