To paraphrase another Australian " That's not a saw, this is a saw". Just around the bay from me there is a sawmill run by two brothers who mill with this frame saw. They started off as boat builders and bought the saw as it is good for sawing large and curved timber ideal for boat building. Since then they have been so busy milling wood for others they don't seem to be building many boats.
Here are some pics I took while looking around (with there permission).
That is a way cool saw. The proof is in the cut and the closeups on the website look like it cuts really smooth. You can tell it was well built with the heavy castings. Thanks for sharing.
