The Basic Orthogonal Spaceships were, after the [Glider], the first spaceships to be discovered. They come in three varieties, with names based on their size: [Lightweight Spaceship], [Middleweight Spaceship], [Heavyweight Spaceship].
Even longer spaceships are not self-sustaining, because their sparks interfere with the body of the spaceship. They can be supported , by other spaceships.
Spaceships can also be refered to by the length of the keel of the spacship-- 4, 5 and 6 respectively. Overweight ships have keel lengths of 7 or greater, but are not by themselves objects. They can, however, be supported in Overweight Flotillae.
