Kirt,

The Aussiewing was originally designed for the A class back in the 80s. It has a smaller sectional shape but in fact has a much thicker wall , heavier, more flexable and not as robust as the Superwing. (I think a much softer alloy.)



I think the sectional shape would be the same as your A class mast. (I have one but wouldn't put it on my Taipan.)



The Aussie wing was put on the Stingray when they went to a taller rig with a wingmast. They went from 28ft to nearly 32ft. In this configuration they pumped in heavy air. That is the spreaders would move forwards and then behind the centreline of the mast. Scarey stuff !



I was told, at the time, Goodall designed the Superwing to replace the Aussiewing on the Stingray.

The Superwing worked great on the Stingray and is still used by them.

I understand when they were designing the Taipan in the early days they did try the Aussiewing but settled on the Superwing which is now the only legal mast section.



I also have been told that there used to be a more flexable version of the Superwing available for the cat rigged sailors,

very slightly thinner wall, but they are no longer available.



This is my understanding.
