I got this baby up to 3kts at a couple of points. I am glad I cut my tiller off so it never extends past my rear decking - PD Racers are sailed from the back and a long tiller is a real pain (in the ear, usually). She heeled well a couple of times, and even with my sail hoisted as far as possible up the mast, I never even thought of it going so high as to capsize. I am truly amazed at the stability and versatility of this design.
