As alterações feitas no WILD OATS XI E
• The section of the hull forward of the mast would become more streamlined and provide additional buoyancy. This feature would greatly reduce the tendency to nose-dive, so the yacht could then be driven downwind faster and more safely in strong winds. It would also present the opportunity to increase the sail area (horsepower) and make the sail-plan more efficient.
• Upwind speed in light winds (up to eight knots) would improve as a considerably larger headsail (a J1) could be set. The new sail measures in at 280sq metres – 20sq metres larger than a doubles tennis court, and 23% larger than the existing J1!
• The bowsprit was redesigned to be significantly longer than its predecessor. This meant the spinnakers being carried downwind would be more efficient, and therefore provide more drag-reducing lift.
• The longer bowsprit would also allow for the largest spinnaker to be increased in area by 120 square metres to 965 square metres. Its total area is now greater than the wing area of an Airbus A380 passenger aircraft!
• The DSS (Dynamic Stability System) hydrofoil wing has been modified to provide more lift forward and contribute to a reduction in hull drag. This will also result in an increase in speed when sailing downwind. New, deeper, daggerboards have also been fitted.
• Through the removal of some old non-structural internal components from the hull, and the use of the most modern materials, the new-look Wild Oats XI hull is more than 500 kilograms lighter. An additional 300 kilograms has been saved through the use of new, ultra-light cloth for the manufacture of the new sails. This fabric is the same as that being used in the construction of some components for the Boeing Dreamliner aircraft.
Wild Oats XI is recognised as the most successful yacht in the 71-year history of the Rolex Sydney Hobart race, but this year she is likely to face her stiffest competition since being launched in 2005. For example, Jim Clark’s Comanche set a 24-hour monohull sailing distance record of 621 nautical miles during the recent Trans-Atlantic race. The distance covered was just seven nautical miles shy of the total course length for the Hobart race. Wild Oats XI is the current record holder for the Hobart race with a time of one day, 18 hours, 23 minutes and 12 seconds.
