A tagalong (or less commonly a tugalong[1]) is an object that is not a spaceship by itself, but can be attached to one or more spaceships to form a larger spaceship. For example, Canada goose is a spaceship made by attaching a tagalong to the back of a glider. Well-known tagalongs include Schick engine, fly, sidecar and sparky.

A strict tagalong is one that does not affect the tagged spaceship in any way. For example, the lobster is not a strict tagalong, but Orion 2 is.

Pushalong

A pushalong is a tagalong that is located at the front of the spaceship that it is attached to. Pushalong 1 is an example that was found by David Bell in 1992 that can be attached to the front of a middleweight spaceship.[2] Another pushalong can be seen at Bulldozer. Further notable examples include cottonmouth and the extra wings for lobster.

Sidecar

A sidecar is a tagalong that is located to the side of the spaceship that it is attached to. Sidecar is a notable example which attaches to a heavyweight spaceship; there also exist sidecars for Corderships, middleweight spaceships and 7WSSes.[3]

Still life tagalong

A still life tagalong is a tagalong that takes the form of a still life in at least one phase. An example is shown below in which the tagalong looks like a pond.[4] The smallest known example, which is also the only known natural example, is MWSS and HWSS dragging block. Certain other such reactions, such as a block being pulled by two sparkers of speed (1,0)c/p (p for period, p ≥ 4), are known.[5]
