Please help me find this movie.
It is a B movie from the 90’s, there is a married couple on their boat/yacht and a redhead maid/helper. Three men board their boat in the midle of the sea, turns out they are terrorists/criminals. The redhead girl sleeps with one of the badguys to get his trust. When a police boat approaches, the main bad guy forces the girls to take off their tops to make it look like a fun trip, while having a concealed gun pointed at them.
I wonder if you’re remembering “Dead Calm.” Nicole Kidman is in it, and she’s got red hair. It’s been so long since I’ve seen it, I don’t remember the plot that well. I do remember her boat is invaded by a murderer, and there’s an intense dynamic between them.
