I read a (paperback) book in the late 80's about the struggles of a starship captain who struggled against prejudice and other issues, because he was born of the union of two different beings. This captain, as a result, was biologically both male and female.
The book, as I recall, was named after his/her starship - and I remember that the author's name began with initials (like C.J.? or the like). I also remember that the author's name may have been a pen name and that the author was a woman.
