Cis-boat with long3 tail is a 12-cell still life.
Construction
This still life is known to be constructible with 5 gliders.[1] Some alternate syntheses can be found in Mark Niemiec's database.[2]

Occurrence
Among the 121 still lifes with 12 cells, this is the 65th most common still life according to Catagolue.
There are no collisions in octohash, octo3obj or octo3g databases with this still life occurring in the ash.
Isomers
This still life is comprised of the normally stable boat with a normally unstable long3 tail attached. While it technically has no isomers, it is named cis due to the corner part of the tail being closer to the boat; the other "isomer", trans-boat with long3 tail, has this corner part slightly farther.
Unlike the trans-version, the cis-boat with long3 tail is the smallest way in which a boat can have a tail of a given length attached to it in cis orientation - shrinking the length of the tail would result in unwanted births and as such the configuration would no longer be a still life.
