Encumbrance of a body, stunned or otherwise

By ThrakaMcKragen, in Star Wars: Edge of the Empire RPG

A couple of (related) questions: What is the encumbrance value of a silhouette 1 character? As in, you need to carry your friend or are taking on refugees in your cargo space. My group has been using 8, but none of us can remember where that number comes from.

Tangential followup: The strain taken from the Stun # quality ignores soak, but strain taken from the Stun Damage quality does not, correct?

And finally, in a lot of the new Star Wars media, fighters are attached to bigger ships through docking clamps. Rules for clamps haven't been released yet, right? If not, how does (for a sil 4 ship) allowing it for 1 hardpoint, can attach up to two sil 3 ships, but gives -1 handling sound?

5 + Brawn for the body itself, then add in any gear it's carrying (but probably still allowing it the reduction on a set of worn armor/clothing).
