Well I own an Australian built 1984 Cavalier 975 (32 feet), and have the brochure and price
list from the original purchaser. So in Australia at least they were still in production then. As far as I know the 39 continued to be built by them for some time, and I thought the hull
design (and moulds??) was passed to Bluewater Cruising Yachts, a boat builder
on Lake Macquarie (although the previous thread here suggests otherwise).
Cavalier 39 Technical Information
All the Cavaliers have a great reputation for being sturdy and well mannered boats.
For the record
, here is a good article about the history
with review of the 32 footer.
