Tractor Beams should be in relation to the two ships. You can "hold" the target, but only in relation to you.
A danube shuttle trying to "hold" a cube will maintain position with the cube, but end up getting dragged along because the cube's not really being slowed down much.
"Don't let them promote you. Don't let them transfer you. Don't let them do anything that takes you off the bridge of that ship, because while you're there... you can make a difference." - James T. Kirk
