Can't see this working: When does a legitimate fishing boat become a trafficker's transport?

Only in the time after they've paid for it and then filled it with migrants and set out. Could be just a few hours.

If they're actually stealing these boats then there's no time at all.

IMHO the correct thing to do is when the migrants are picked up or even manage to get to Malta or wherever that they're taken straight back to Libya. Once it gets out that this is not a guaranteed route into the EU this problem will solve itself.

The traffickers will try other routes but at least these deaths will be avoided.
