I first thought according to the DVD cover, that this is a color movie. There is also a (probably) related 1975/1976 color TV series called

"Volny chernogo morya", wich is also very good (coming soon), maybe based on the same book.

Novel by Valentin Katayev. I don't understand Russian, so I can't say much about it, but this look very good. Russian title "Белеет парус одинокий", English title "The Lonely White Sail". I checked only some parts, and have to check again completely. Rating 5-6 for now.
