The full length battens are "bamboo sticks" so the sail is a little wrinkled as they we sewn in by hand. We now use a lead weighted swinging centerboard and water ballast. In sailing mode the boat tracks very well and it feels more like a keelboat than a dinghy. I could leave the rudder alone and go forward while the boat kept going. The rudder is very powerful. It is very long and narrow boat, and when the breeze picks up the speed goes up quite well.
