@maritimemaster: The sea itself tells you the wind speed, no anemometer needed. The Beaufort scale grades wind force by the face of the water, so you climb the ladder from Force 0 mirror glass to Force 12 white water with the Met Office speed band, probable wave height and state of sea on every rung. Learn the six faces, and save this before your next watch. #beaufortscale #seastate #sailing #seamanship #maritime
