Overboard

I heard about this movie and have been hunting for it for several years. I see it listed on IMDb but have been unable to obtain it. I saw it once on ebay listed by an Australian but was outbid. I would so love to see this movie. We heard about it from a sailing club that was talking about the bad luck of "renaming" a sailboat. It sounds like a great sailing movie not to mention about the difficulties the couple seems to be going through. The renaming thing is just a superstition thing the club had been talking about, but I guess that is part of the mystery in the movie about the boat??? Please, if anyone knows how to buy or rent one, please let me know.
