You want to know if learning new languages is available on Seabourn.
Not that I recall (I really do not think so)
The only ship I recall seeing regular language classes is Crystal which has actual classes with instructors to teach you basic European languages.
Cunard has computer-based foreign language training, but it is basically just a program you can buy abd do yourself at home.
I am the editor, but I also speculate, ask questions and play devil's advocate. I reserve the right to change my mind.
