I don't believe there was. They released the Flow series for windfoil and later released the Aero series for winging. They changed the bolt pattern when they did that. Craig Gertenbach works for Duotone and frequents the winging forum here. You can check with him.

Was there a shorter fuse version of this foil?
I've got this fanatic flow 900 - 215 90cm mast and fuse and wondering what other fanatic wings and fuse are compatible.

I've been using for windfoil and now trying to learn winging with it but thinking i need a bigger foil to learn and go in less wind maybe..

There is a 1000, 1250 and 1500 in the Flow range.

The 1000, 1250 and 1500 wings are part of current range of windfoiling wings. I believe the foil that Mobz has is the version two foil, that came in 900 and 1250. I believe the 1250 is the same profile wing but the hole spacing is different.
I did my first winging sessions on a 90cm fuse. It was fine. However I think learning on a 900 will be very difficult. Life would be much easier with at least a 1250. Many sailors start with 1500 or 1700. But I know Mobz is not a big guy so 1250 would do.
