Are there any recent breakthroughs in Aso spinnakers?
LL: Asymmetrical development continues as the perfect sail shape for each design/boat type and angle is determined. Unlike symmetrical spinnakers, there is a perfect shape for every wind velocity and angle. One aspect critical to optimal performance is sheet lead position. Like trimming a genoa or Jib Top, it is critical that the lead be changed as the TWA fluctuates. The leading angle of the asymmetrical must break evenly top to bottom just as if you were trimming a Jib. Because there is only one perfect shape for each angle, the goal is to produce a sail with a wide range. Much of this work must be done in testing on the water, but here at Quantum we are producing great results inside the wind tunnel. Once only popular on skiffs and sportboats, ASO kites are now becoming the accepted norm on all types of performance boats. What is the reasoning behind the new acceptance? LL: Originally, like anything new, a change toward asymmetricals was met with resistance. As new boats like the Me
