I just purchased a 1979 Spacesailer 20, made in Missoula, MT, USA, apparently under license of Swarbrick Brothers Yachts, Australia. Can anyone tell me if the Montana version and the Australian version of the Spacesailer 20 are the same?

I am finding it difficult to find specifications for the Spacesailer 20. If any forum members can refer me to information, I would appreciate it.

Can anyone give me general information from their personal experience with this boat model?

Thank you.
