I've tried to locate one of these rare boats for a few years. There was been interest in building NEW Deltas on the site. I thought this thread may give some ideas. This is a 13 foot OPEN wing style hull. There is not many pictures on the web and the video's show the wrong type motor and poor engine set -up. I think with a set-back and a short shaft T850 motor the boat would be a very strong runner.
They only built 15 boats.
