|caption = A decent number of very long ships, although not enough to be almost all, form from the right half of generation 7 of this pattern, where generation 0 is a [[bakery]] predecessor with one cell moved to an adjacent location. Some of them go through the sequence shown here, while others reach generation 7 in a different way. Because this is a common predecessor, the very long ship is often accompanied by two nearby [[boat]]s. | |||

Very long ship (or long long ship) is the long long version of the ship.
It is the twenty-ninth most common still life in Achim Flammenkamp's census, being less common than tub with tail but more common than table and table.[1] It is also the thirty-fourth most common object on Adam P. Goucher's Catagolue.[2]
It is about one-fifth as common as the long ship but almost 2,000 times as common as the long^3 ship.

Synthesis
On March 28, 2007 Dean Hickerson found a 4-glider synthesis of this still life.[3]
