Island Prey (2001)

Catherine Gaits (Olivia Hussey) is married to wealthy businessman named Parker, and they're on vacation looking for a yacht to buy. Rough life, right? Right when they're about to tour the yacht they're buying, Parker has to leave on business, leaving Catherine to check it out alone. The boat broker Patrick is immediately into Catherine and takes her out to dinner, ultimately seducing her, thanks to the absence of her slightly neglectful husband, letting us get a great look at her boobs. It's a great night until she wakes up and realizes what she did (oops) so she goes back to her husband and thanks him for the night. Only, Patrick isn't so keen to let her go... it gets a little rough, but we at least get a great look at Olivia in the shower!
