I used to have a Clipper (CHB/Marine Trader) 34, of 1975 vintage, and of the sedan, now called Europa style - even rarer back then than in 1984. But yes, as Frosty says - they share most things with the tri, or aft cabin versions. The hulls were the same, and most mechanicals. Just the positioning of the bulk-heads the main difference, and obviously the smaller useful cockpit area of the tri-cabin version, and truncated length of the saloon to allow for the aft cabin.
In later years the Europa versions have tended to vastly outnumber the aft cabin versions on many designs, as the more practical and roomy cockpit of the latter took hold. Your vessel would probably be what we in Oz called the Blue Seas 36, which was, for quite some time, my anticipated move-up-to boat. Never happened..! The 34 proved adequate for all we needed. Great layout. If you buy one, you'll love it. And yes, they are very seaworthy.
Here's an example. Look like yours..?
