Cis-boat on dock (or up boat on dock) is a 15-bit still life.
Commonness
Cis-boat on dock is the fifty-seventh most common still life in Achim Flammenkamp's census, being less common than block on cover but more common than eater head siamese eater tail.[1]
It is the 59th most common still life on Adam P. Goucher's Catagolue, being less common than block on cover but more common than cis-block on long bookend. It is the 2nd most common still life with 15 cells, being less common than moose antlers but more common than trans-bun and wing.[2]
Most cis-boats on docks form via generation 1 of this sequence, which has at least two 9-cell parents shown here. A similarity can be seen between generation 3 of this sequence and the activated loaf mentioned in the block on dock page.

Glider synthesis
All strict still lifes with a population of 22 or fewer cells, all oscillators with 16 or fewer cells, and all spaceships with 31 or fewer cells are known to be glider-constructible. A glider synthesis of this object can be found in the infobox to the right.
