The America’s Cup showcased foiling under sail; something no one can ever unsee. Foiling is the new standard. Swing keels are also a standard in the search to reduce wetted surface.
It is hard to imagine that “Charisma” was once the standard for speed under sail. Construction with aluminum lent itself to very strong boats that could be easily altered. “Charisma” was perhaps the penultimate IOR boat.
For ease of altering a boat nothing can beat aluminum. Carbon fiber is however in a class by itself for strength to weight ratio; making today’s yachts lighter and stronger than ever.
The book about the three “Carinas” written by Richard B. Nye came out a few weeks ago. The saga of “Carina” continues as she having sailed to Australia to participate in the Sydney-Hobart race from England after having completed the 2011 transatlantic race and now sailing home to the East coast of the United States where she will sail in the Bermuda Race this June. Follow her story HERE.
The story of “Carina” is interesting from many points of view. Her conception was the culmination of years of experience of ocean racing by the Nye family. She was launched in 1969. This is where the story is so interesting as we look back. At the time two racing rules dominated the world: the CCA in the United States and the RORC in the rest of the world.
I have added the photo of “Outlaw” to illustrate the RORC rule. Anyone wondering where the pinched ends under the IOR came from. This was one of the compromises in order to achieve one rule.
Back to the “Carina” story. In 1968, the Nyes had won class in the Bermuda race with the old yawl, but wanted a new boat. The new rule was still being negotiated, no one knew what the final rule would offer, so Jim McCurdy and Bodie Rhodes were tasked with designing a boat that would rate well under any circumstances. The result was a boat that is still winning races 40 years later
