Restrictions: Scum, Quadrijet Spacetug only
Removes: Spacetug Tractor Array. (probably worded "You cannot perform the Spacetug Tractor Array action")
Adds White Boost action.
Ship ability: " Engine power reserves: When you perform a Boost action you may use the rear guides. If you do, treat that action as red."
Think of it as someone stripping out the tractor emitters and shunting the power made available by doing so into the engines. Makes it more nimble and has a decent synergy with Pattern Analyser, at a cost of course. I prefer the stress for the ship ability being used over the other red token options because it limits how often the ability can be used, even with PA equipped to the ship. No clue as to cost, maybe 0-1 pts as a start since it blocks the use of the tractor array. Probably a point or two too low though.
