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
Sails of the South Tipner Bridge. The Sails are illuminated in violet at night. In addition, there are bird roosting sites in nearby Tipner Lake. The sails of the south was part of the redundant but later revived gateway project, this and the refurbishment of the nearby bridge was the only parts of the project to be realised. The bridge intended to take the M275 over a roundabout of an unbuilt junction roundabout. In 2006 vandals smashed 21 of the 24 lights that light up the structure. As of 14/07/2015, they are yet to be fixed. Sails of the South The Trimast, commonly referred
