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]
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.
