Author Patrick Riley concluded from this film that Loni Sanders used the alias "Terry Galko" in the film's credits. A viewing of the film Half the Action (1980) reveals that Riley was wrong. There it becomes clear that Terry Galko is a separate actress. The credits in "Sexboat" really don't help identify who Galko is. It turns out she plays the hard-to-see sex partner of Randy West in the women's dorm. It isn't obvious but this character later reappears, now with the name "Nancy," as the girl who bets with Pamela Jennings that Turk Lyon (in drag) is really a man.
Little Oral Annie's scene partner was her husband, Buddy Owen, acting under the name Douglas Fairbank.
