Seven of Nine is the boats name. It got named that becasue during construction a wren bird landed in wet epoxy on the hull and got stuck briefly. It lost 9 feathers, seven on one side and two on the other. It flew away quickly and has not been back in my garage since.
So that boat did well and appears that it is going to be able to do wind speed or sometimes better depending on how you are running. Down wind I could do windspeed. With the wind on the side and the sail in airfoil shape producing lift it go somewhat better than wind speed. It also went into the wind well and should do better with some teaking.
See photos and video on the designs page at rogermann.org on the boat side. Thanks,
