What this video covers

During a transatlantic passage from Havana, Cuba, to Galicia, Spain, in May 2018, the crew of the sailboat Copérnico adopted Coordinated Universal Time (UTC) as their standard ship time.6:27 Navigating eastward across six time zones, the crew rejected the practice of adjusting clocks every 15 degrees of longitude to avoid confusion and administrative burden among the five people on board.3:13 Using UTC simplified the synchronization of watch schedules and aligned with the timing of incoming meteorological reports.6:30 While the crew maintained UTC for ship operations, they acknowledged that a sextant-based navigation strategy might have necessitated a second clock set to local legal time.6:53 Ultimately, the crew found that the rigid structure of clock time diminished in importance as the rhythm of the voyage became dictated by the sun’s position and the physical demands of the watch system.7:15 The transition required the crew to move away from land-based habits and rely on biological cues to manage sleep and daily activities.7:38
