Do you know how sailors describe the state of the sea? In this video, we will learn about the Douglas Scale, created in 1917 by Captain Henri Percy Douglas. This essential tool classifies the sea based on the height of the waves, from level 0, which represents calm waters, to the impressive level 9, when the waves exceed 14 meters! Understand how factors such as wind, currents and swells influence the agitation of the ocean and how this scale is vital for navigation safety. Don't miss the chance to discover more about the mysteries and challenges of the maritime world!
