This attachment increases the difficulty of detecting the vessel with sensors by two. As far as I can tell, the base difficulty to detect a ship with passive sensors is 0 and with active sensors is 1. This would mean that the adjusted difficulty is 2 (passive)/3 (active). Is this the way others are reading it?

Using open space rules that sounds about right. Additional encounter elements would of course change those numbers...

I guess this begs the question, do you just roleplay sneaking past an imperial blockade or do you work up a skill check(s) to accomplish the goal?

We see a bit of vehicle stealth in ESB with the Millennium Falcon attaching itself to Vader's star destroyer then floating off when they dumped their garbage.

I'm kind of curious how everyone else would adjudicate that?
