8m catamaran Information

Gday Blokes ,

I was wondering if anyone could tell me anythin more about these catamarans?
All I have been told is that its a 1975 Hull and was made in Sth Africa.

If anyone knows the make and model or could steer me in the right direction that would be great.

Thanks

To be honest I personally have never seen one of these in SA. It looks almost too modern to be from 1975.
