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. It is also the thirty-sixth most common object on  Adam P. Goucher's Catagolue. 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 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.
