Before GPS. Before radar. Before satellites.
Sailors once measured a ship’s speed using nothing more than:
🪢 a rope,
⏳ a sand timer,
and the movement of the sea.
That’s where the word “knot” was born.
Smarty explains how one of the oldest navigation methods in history still influences modern shipping today.
🚢 Why do ships use knots instead of kilometres?
🌍 Why are nautical miles connected to Earth’s coordinates?
⚡ Why can some ferries travel twice as fast as cargo ships?
The ocean has its own language, and every maritime professional still speaks it.
With Smarty, maritime knowledge becomes easier to explore.
