The Coe ship is the first period-16 c/2 orthogonal spaceship to be discovered; by Tim Coe in October 1995. It works as a puffer engine because it produces a long spark behind it as it moves. It consists of a lightweight spaceship pulling a heavyweight spaceship that is modified to give the big tail spark.
Despite its small size, it never appeared in a soup until 2015 when apgsearch was devised. By doing so, it became the first naturally occurring non-period-4 spaceship to occur in Life out of an asymmetric random starting pattern. A second Coe ship appeared in June 2016, and three more shortly after. However, the Schick engines and the copperhead have appeared in symmetric soups.
Just a few of the many rakes and puffers which can be powered by the Coe ship
