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 Dawn Sails of Dawn Sails Of Dawn is an ocean racing yacht and cruising yacht, one of the last boats John Laurent Giles saw launched before his death in 1969. It was built to Lloyds 100A1 certification, while being also under Royal Ocean Racing Club certification and also to Lloyds 100A1 for the owner DD Morell of Mitchell Construction. Only three yards in Britain submitted tenders for the build, others stating the quality unattainable in the time-frame , and so it was down to two yards, McGruer of Clynder and Robertsons yard. McGruers were chosen for the price of 48,000 British
