Forces on sails (3 m) = 5-m/s (≈10-knot) wind at 3 m above the water would be approximately "V" (15 m) = 6 m/s (≈12 knots) at 15 m above the water. In hurricane-force winds with "V" (3 m) = 40-m/s (≈78 knots) the speed at 15 m would be "V" (15 m) = 49 m/s (≈95 knots) with "p" = 0.128. This suggests that sails that reach higher above the surface can be subject to stronger wind forces that move the centre of effort ("CE" ) higher above the surface and increase the heeling moment. Additionally, apparent wind direction moves aft with
Scarlet Sails (film) sets about to make it come true. This was the film debut of Anastasiya Vertinskaya, who celebrated her 16th birthday during the filming. She went on to star in such Soviet classics as "The Amphibian Man" and "Hamlet". Locations used in the filming include Koktebel and Yalta in Crimea (Russia), Baku in Azerbaijan, and Pitsunda in Abkhazia. Grey's ship "Secret" was actually the training ship "Alfa" from the Rostov Naval School. It was outfitted with 2,500 meters of scarlet parachute silk procured to satisfy Ptushko's demand for authenticity. Scarlet Sails (film) Scarlet Sails () is a 1961 Soviet film produced
