An overweight spaceship (or OWSS for short) is a would-be spaceship similar to the lightweight spaceship, middleweight spaceship and heavyweight spaceship, but longer. On its own an overweight spaceship is unstable because the three cells at its top do not die off like the corresponding sparks at the top of the smaller spaceships. Nonetheless, it can be escorted by true spaceships to form a flotilla.
It is also possible to stabilize the OWSS with more OWSS, which then have to be stabilized by more OWSS/A *WSS. An example is shown below.
