Sea Partner
My DD had that problem her 3/C year. She was then assigned a 2/C male engineer to be a Sea Partner with. It worked out wonderfully and they have remained friends.
Not only was he a great guy, but he also knew 'the ropes' since he had all ready been to sea. He assisted her with Sea Project questions and gave her good advise. He accompied her on Port calls. They even had meals together. He was even from the same state and I knew his parents through the Parents Association. On the night before they boarded ship, he called me and introduced himself. "Ma'm, I will look after her. Don't worry about anything!"
Well, what more could I say????? When she was 'kidded' about going to sea with an upperclassmen stranger....she just replied, "No, My Mom knows his Mom and I feel safe."
If your DS can not find someone, the Officer will help in the assignments. Have him go in to talk with them.
