The ASG3 went radical from A class standards and has not been received well. Ashby has his hands full I imagine with the AC, so I would not consider his jump to a DNA anything other than convenience.
Ashby's company builds the ASGs. When AHPC shifted boat production offshore, one of their boat builders moved over to build boats for Ashby. (Ashby started of as an AHPC sailmaker before going out on his own). It would not supprise me if Ashby bought the DNA to have a good look at it before bringing out the next ASG design. Nacra had a good look at the Capricorns and Tigers when designing the Infusion.
