I recently returned from the Hamburg Boat Show and had a chance to meet Dr. Peter Wittkopf and to see his proa, which he calls the Deltro.

It is a very nicely done prototype of wood epoxy and some carbon.  He had a video showing it sailing.  It looks pretty good and he could shunt in just about 12 seconds.  It was hard to see speed in the video, but I'd guess he was doing about 10 to 12 a few times.  This is about a 20 foot proa.

One interesting thing is that the little hull is very little and articulates much like Adreniline's amas did.

There is no rudder.  You steer by shifting weight after setting up the rig for about the right balance.

Best Regards,
