Cis-boat trans-line tub is a 12-cell still life.
This still life is comprised of a normally stable tub and a normally stable boat connected by a line. This is one of two possible isomers, named cis due to the corner part of the boat being closer to the line; the other isomer, trans-boat trans-line tub, has this corner part facing outwards.
The closely related pattern "boat cis-line tub" is an induction coil, in much the same way as the integral is a still life whereas the house is an induction coil. Note that there is only one valid isomer for the cis-line arrangement, analogous to trans-boat trans-line tub, as the cis- arrangement would cause unwanted birth between the boat and tub.
Among the 121 still lifes with 12 cells, this is the 32nd most common still life according to Catagolue.

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.
