We have beat a C&C99, J/100, J/32's, and a J/105 in the last three races in Nashville!
For lite air I really eased the headstay & shrouds. Floppy loose backstay. Traveler all the way up with mainsheet eased. We found the best speed with crew on low side just behind the shrouds, low & out of the slot. I sat as far forward as I could get and steer. We popped the spinnker if we could use it only a hundred yards. The cars were way forward with our 150. I was moving the tiller as slowly as possible.
Great crew work!
