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.
A decent number of very long ships, although not enough to be almost all, form from the right half of generation 7 of the following pattern, where generation 0 is a bakery predecessor with one cell moved to an adjacent location. 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.

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