Hi Michael
My Father has recently purchased one of these GRP racing dinghies. It needs some work before it can be sailed, but we have been unable to locate any information on the web other than some general info about designer Paul Wright:

and a reference in the dinghy database:

Do you still sail yours? Have you made any other contacts since your post?

Best Regards
