Hello Matt and Jo, I have no information just yet but have put feelers out to Graeme Broxam our Guilds well know Maritime Historian. I have also given him a link to this forum post.
She is obviously of good pedigree having been built in 1956 by Geoff Knight and designed by Jock Muir (?); then in the mid 80’s was converted to a motor sailor by Geoff Cuthbertson (commissioned by then owner Barry Scott).
I do volunteer work for the ANMM in regard to the Australian Register of Historic Vessels (ARHV) and she is not on that register but to me deserves to be. We will help you find out more.
