Going Overboard (1989)

Shecky Moskowitz is the zany cocktail waiter on this pleasure cruise with stunningly gorgeous beauty queens. Since the ship's comedian, Dickie Diamond, gets all the girls by being a funny man, Shecky dreams of taking over as the ship's comic. Unfortunately, Dickie doesn't want the competition and refuses to give Shecky a chance at performing as his warm-up. As fate would have it, Dickie gets locked in the bathroom and in need of a comic act, Shecky is given his big break at stand up. Suddenly all the beauty queens become interested in funny Shecky. But the big question is: will he sink or swim? Shecky's antics rock the boat in this hilarious sea adventure which contains hysterical comic sketches and sexy fantasy sequences.
