Boat tie long boat is a 12-cell still life. As its name implies, it involves a boat having been tied to a long boat.
Commonness
Among still lifes with 12 cells, this is the 14th most common still life according to Catagolue. Among all still lifes, it ranks 108th.
There are two collisions in the octo3obj database and one collision in the octohash database with this still life occurring in the ash.
Construction
It is possible to construct a boat tie long boat with 4 gliders. A number of known syntheses can be found in Mark Niemiec's database.[1]
