The Cruise That Desecrated Shabbos

The story of one of the Rebbe's most storied Halachic showdowns, in which he uses his Halachic and engineering expertise in concert to debunk the false claims of Israel's ZIM shipping company that their transatlantic cruises were not violating Shabbos (or had no choice but to do so). This was originally a three-part Shiur, condensed into a single Special Episode.
