Years ago the Finn 8 and a smaller model, either 6 or 7M, were marketed in Aust. Unsure if built here but at a guess, probably. Scandinavian design,like the dear old 26ft sailing Folkboat I once owned.There is one on my marina in northern Sydney, and bogranjac1 on TF has one I`ve been aboard. Neat utilitarian boats,not huge on creature comforts or space, a Seapiper predecessor. The split accommodation with a centre cockpit is disruptive to usual onboard living but the keen could get used to it, I expect one end is for sleeping, the other for living, cooking,food storage etc. Probably has a cult like following and surely runs "on the sniff of an oily rag".
I`m familiar with the Contessa 25 sailboat, English origins?,sturdy long keel boat, similar sailing properties to the Folkboat.
