ship

1. ship (noun) — sense 1

Definition: A water-borne vessel generally larger than a boat.

2. ship (noun) — sense 2

Definition: A vessel which travels through any medium other than across land, such as an airship or spaceship.

3. ship (noun) — sense 3

Definition: A spaceship.

Example: I don't know if there is another standard method, but the following approach works: Consider the collision of gliders from three rakes that produces a medium spaceship in the _same_ direction as the rake. This ship will follow along to the next collision point, which will not produce a spaceship, but rather some stable garbage, consisting of a block and a beehive.
