To get information regarding out Halcyon 23 another of Offshore Yachts boats we went to the website. We looked through available articles , then we emailed them. Someone gave us archived articles that related to our boat
. They were helpful in the extreme. I can only assume they would assist you as well. In fact did point someone else on Lake Ontario
to them and they received much help as well.
I will post the website link here, please note, when I tried to access the link with Mozilla I had trouble, but Internet
explorer experienced no difficulty.
On their website there is an archive section, you can check through it for articles pertaining to the Nantucket
Clipper. They date back as far as 1973.
Offshore Yachts burned to the ground, ( sorry I forget the date) and never went back into production. After visiting the UK I realized there were many of these boats in great condition being saled all over the place.
I hope this is of some help. I will try to
access some more information for you.
