How many turns does it take to tow a ship? Tow ship TR + (Towed ship TR x 2) = Number of turns spent. Where TR = Turn Rate.  So towing in the Ferrengi assault trader with your ISS would cost you 8 turns. Towing in that CT with your ISS would cost you 16 turns.
 
You cannot tow another ship out of a Fed space sector. You can cloak a manned or unmanned ship if you're in the same sector and the tractor beam is activated. I have only tried this with another corp ship of my corp. THEORY: I wonder if you could to do the same w/cloaking a non-corp, Alien or Ferrengi ship. That would be interesting. Would the other player find his ship when he entered the game again?  If so, what would be the consequences?  Would it un-cloak the original cloaking ship or just the ship that was towed?  Wouldn't be a good tactic if the original cloaking ship were un-cloaked too in the same sector. That could be disastrous. "VERIFY BY EXPERIMENT." (DMD 2/26/96)
