Bucky cable
From AndroWiki
A Bucky cable is an intelligent harpoon, which tracks its targets by the instructions of the computer on board of the firing ship. It is primarily used to recover any kind of salvage or to haul damaged ships. It consists of high-strength materials, based on Nanotechnology and is as a result hardly destructible.
The Maru and also the Andromeda Ascendant have such cables installed.
