Because of its elusiveness and because of the poor quality copies that did circulate, Top Sensation developed a reputation that it really doesn't deserve. It is not a thriller. The exploitation goodies, while present, are not as numerous as what one might expect giving its X rating (now, easily an R). Still, Top Sensation provides undemanding viewers with a good time throughout its short running time.
The film could be accurately called seven loonies on a boat. Mudy is a rich, decadent bi-sexual on a private cruise. Her yacht is staffed by an ambitious, morally dubious couple, both of whom are sleeping with the boss. In addition, there is a hired companion (the lovely Edwige Fenech) along to seduce the boss's son. The young man suffers from a mental illness which makes him act like a child. In 70's swinger psychology, mom thinks getting him laid will turn him into a man. The only thing is that boy won't come near his girl toy (turning down Edwige Fenech? The poor boy is worse than I thought!). When the yacht runs aground on a sandbar, the son sneaks off to explore a nearby island. There, he befriends a young, innocent shepherdess. Mom and company are thinking the girl might be good at tending something besides sheep, but what to do with her husband?
This is a silly film, but one that is hard to dislike. It moves along at a nice pace. The viewer is never bored. There is a pleasant music score. The scenery is gorgeous and so are the girls. Edwige Fenech, Rosalba Neri, and Eva Thulin all radiate charm in their bikinis (and occasionally less). In addition, once in a while director Ottavio Alessi will go for an arty touch just because (check out the editing on the scene where the two more experienced girls make up the shepherdess). As nautical themed sex dramas go, Top Sensation is far more fun than Roman Polanski's Bitter Moon.
