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

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 also the thirty-sixth most common object on Adam P. Goucher's Catagolue.[3] It is the rarest still life with a 3-glider synthesis, although the pentadecathlon is even rarer.
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.
