What if no magnetic compass: other ways fleets still crossed oceans

A 5-beat faceless video outline for “What if no magnetic compass: other ways fleets still crossed oceans” in the Historical what-ifs niche, derived from caption timing of 2 reference videos.

Angles

• Pose the hinge: fleets without magnetic compasses still crossed open water
• Gallery of methods: stars, winds, birds, coastal pilotage — caption-backed
• Honesty beat: methods had ranges and failure modes; not magic navigation
• Close on what the compass later standardized rather than invented from zero

Beat-by-beat structure

1. Hook (0:00–0:30): no needle — still an ocean. Promise the toolkit.
2. Celestial (0:30–2:30): stars and latitude thinking in plain words.
3. Environmental cues (2:30–4:30): swells, birds, clouds over islands.
4. Limits (4:30–6:00): fog, overcast, and why instruments still won.
5. Recap. Original narration only.
