The group consists of:
Technician / Slicer (No Piloting or Astrogation skills, but has Mechanic and Computer)
Colonist / Politico (Has Charm and Negotiation)
Hired Gun / Mercenary Soldier (Has Gunnery)
Smuggler / Pilot (Has the Debt Obligation)
Under the circumstances the YT-1300 was said to owned by the Smuggler. However, how much does he have to pay the others as crew or how much do they have to pay him as passengers? None of this seems to be in the books. Making the others co-owners was going to stretch the games credibility as the Pilot was the only character with the back-story to suggest he owned the ship. All the other PC's have skills that make them useful to the ship in one way or other however, so they can be used as crew.
Any help here would be appreciated.
