This may be the mother lode of boat-related classic TV: the great 1950s Victory at Sea series depicting the naval side of World War II. Prepared with the blessing of the US Navy, music by Richard Rodgers, arranged by Robert Russell Bennett. Authentic footage from the US, allies, and the enemies. Great history that will keep you glued to the screen on these cold winter nights.

I just watched this episode on warfare in the Arctic. Commando raids on occupied Norway, Arctic convoys from Scotland to Murmansk, fighting the Japanese in the Aleutians.
