"We need to know quite a bit more than we do to decide what to do with you two. I take surrenders seriously and I can assure you that you will not be killed or seriosuly harmed if you keep faith with us, regardless of the answers to our questions. The only fear you should have is in dishonestly with us, and I can assure you that we will know if you are lying."
These two personally. Thier names, homes, reasons for going to sea.
How they came to serve on that pirate vessel.
How the vessel came to its current condition and what if anything happened to her captain.
The origen of the strange weapons they used, and anything else they know about them.
The weapons and tactics used by other pirates who might sail these waters.
Specific ship names and pirate captains.
The relations between different pirates if any.
The identity of any "middlemen" used by their ship in local ports to sell stolen goods or ransom valuable property or persons.
Obviously she will be trying to get a feel for these two men as individuals as well as the truth of their individual statements...

"Wait, instead of fencing the goods in a port the pirate captains hand them over to some sea-demon? How do the crews get paid?"
GnomeWorks said:Yolani looks to Remi. "What? Didn't ye hear what I say? We split th' booty amongst ourselves, an' th' cap'n gives 'is share ta th' demon a th' seas. Every man keeps 'is share th' loot, other'n 'im, an' each uses it fer 'isself when we get ta ports friendly ta pirates. Th' cap'n takes what looks ta be valuable an' might be not good fer tradin' as it might draw undue 'tention, an' everythin' else is split by th' crew."
Katherine
"And this sea demon... whose name is aparently known but feared... why would your captain give up his share to him? And more importantly, would you have done the same if your raid here had been successful?"
