Your options for more senior crew include the leader of the marines (who Ruby knocked out), a cleric of Lavashki, who you fished out of the water, the only surviving officer from the frigate and the captain of the second sloop.
The majority of survivors were from the second sloop, with the second largest group from the boarding party.
