Cis-boat with nine is an 11-cell still life.
This still life is comprised of the normally stable boat with a normally unstable nine attached. This is one of two possible isomers, named cis due to the corner part of the boat being closer to the nine; the other isomer, trans-boat with nine, has this corner part facing outwards.
It can be substitutively referred to as the integral with cis-boat, with one pre-block of the integral sign replaced with a boat, however "cis-boat with nine" is usually preferred for this object.
Occurrence
It is the 101st most common still life on Adam P. Goucher's Catagolue, being less common than trans-boat on table but more common than tapeworm. It is the 12th most common still life with 11 cells, being less common than trans-boat on table but more common than boat with hooked tail.
Synthesis
Cis-boat with nine is the most common 11-cell still life without a known four-glider synthesis. The cheapest known recipe requires five gliders.
