The pandemic caused serious worries for those traveling the world’s oceans on sailboats, and also silly ones.

Australian Guy Chester, alone on the 52-foot GC Sanctuary somewhere in the Pacific Ocean, had just finished season six of “Game of Thrones,” and really wanted the final two seasons.

Mr. Chester broadcast a TV-related SOS. In French Polynesia, where the 58-year-old environmental and eco-tourism consultant wasn’t allowed to disembark until going through quarantine, another Australian craft sailed close and dropped off a flash drive with the missing episodes. “I binge-watched” them, he said.
