Its a Tony Castro design. There are two versions, a 36, and a 38' with a "true" or what I would call a "true" sugar scoop stern, not a walk thru sugar scoop. And a regatta version that fills in the back of the sugar scoop for a filled in really raked back transom. Fairly quick for it size and the time frame from which it was designed. I know of two owners locally in the puget sound region with them. Not sure where you are looking. there is another for sale in this region too.
They came either fin or cb models, the fin being the lighter quicker etc. Going across oceans would not be an issue either, as many were raced in some of the longer races back in the 80's.
There is an active owners group at

I have an 84 Arcadia, which is a 30' version of the SS36/38. I would suspect the SS to sail on par with mine, being as both are designed by Tony Castro.
Here is an owners review of the ss36 on the JO site.
