it would have to be a ship with equal(ish) stats so with equal module slots or something and not just be a capture random shjip .... thus meaning youd either have to craft 50 or 100 trins to get 1 dura back or buy/steal from 50-100 other players ... and they shoulod be as rare if not more than a craft not ... so 1-3% drop rate ...
(also ai's dont sail trins...)
