This is a movie starring Scott Bakula and Robert Loggia. Scott's character got lost at sea with his Chesna and Robert is a commercial airline pilot who tries to find him.
It was a small movie but I enjoyed it. I doubt it was ever seen in cinemas (I assume Direct-2-Video or even TV movie).
It is available in a 2pack in the US but with $30 just a bit too expensive (especially since I'm not interested in the second movie).
I was just curious if it was available in any of your localities. Here are the AKAs:
