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 (tradition) united to celebrate the end of the school year in connection with the symbolism of the popular 1922 children's book "Scarlet Sails" by Alexander Grin. During the first celebration, a boat with scarlet sails sailed along the English Embankment and the Admiralty Embankment towards the Winter Palace. Although it was designed to update the rusty revolutionary propaganda, the "Scarlet Sails" tradition eventually evolved into a massive demonstration of freedom from "schools and rules" and has become the most popular public event annually celebrating the end of school year. Crowds of about one million people are treated to a wide variety
