If I remember correctly, the boat was designed by Angelo Lavranos whilst he still was resident in South Africa. Angelo had a finger in the pie with the construction of nearly all of his designes built in South Africa. He now resides in New Zealand and if you do a Google search, you will find his contact details. Send him an email and I am sure he will assist you to answer your questions. I think they were built by Fred Scholtz marine, which has long disappeared off the face of the earth.
