He built a Bill garden modern day sea bird yawl. One of Rudders "LAST" plans before that rag went kaput! Not sure how many others, if at all were built. HERE
is a link to some pics a couple or three years ago when we got in on a trailer, the fall before launching. Gives you an idea of the shape etc.
The design itself has some issues as to how well it turns etc too. It would have been nice of the motor was a bit stronger. Not sure if the tack reads true. Seems to be about half of what it really is turning in my mind. The claim is to run at 1500 or so rpm for best speed performance etc But seems to like about 2000-2200 on the tack, along with get some reasonable speed out of the boat. Not sure of the speed, as a knotmeter is not installed.
It is what it is, when he dies, family will probably sell it, like all things, for as much as they can get. Not sure it will be a lot considering many variables about it.
