Stamford Yacht Club and Indian Harbor Yacht Club hosted 2009 Viper 640 North Americans and delivered two days of great wind for the sport boats- exactly what they need. 37 boats competed in the teaching regatta, which included after-racing chalk talks for the growing class that’s rapidly recruiting new boat owners. As always, Vipers look great in big breeze, so take a look at the photos here and look for them in Sailing World in the spring.
