I love film, even bad film, but this one was just too filled with technical mistakes, bad dialogue and, for a movie about a sailboat, contained more sailboat related inaccuracies than Wiley Coyote has relative to physics. There was one scene, in particular, where someone wrapped a line around a self tailing winch, in a way that would have jammed and taken a long time to fix.
Other major problems, a 50 foot boat is just too small for 7 people, let alone, an official captain and navigator. Captains of boat under 100 feet do not normally bark orders like "everyone on deck", and never have their own navigator. I am not sure where this is all supposed to have taken place, but the tropical fish that they showed could be found in an aquarium, or in India or Australia. They showed giant kelp beds, like you would find in California, and then stock footage of fish that could not be found anywhere near California.
Had the plot been interesting, maybe I would not have focused in on these details, but I can tell you that this master director/producer/writer must have very little experience with sailboats. Cute girls, nice boat, and lots of pretty backdrops, but crazy inane dialogue and a plot as thin as consume'.
I normally like to recommend bad movies, this one I cannot.
