Very long ship (or long long ship) is the long long version of the ship.

Commonness

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

It is about one-fifth as common as the long ship but almost 2,000 times as common as the long^3 ship.

The very long ship forms in generation 17. 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 boats. (click above to open LifeViewer)

Synthesis

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

A 3-glider collision exists that produces a very long ship along with a lot of junk, formed via a glider hitting a bullet heptomino.
