Winging in very light conditions can be very challenging as most of us know, especially getting started. I've had an idea for a while now which I doubt anyone has tried, and would be interested in seeing if it would work.
Imagine having a second foil attached to your mast about 300 or so under the board, would this give you a lot more lift at those super low speeds and as you get more height it would disengage and then allow you to ride on your main foil only.
Both negative and positive comments would be interesting to read, I have a policy of never knocking an idea because everything man made has come from them ??.

Hi elk. I have thought exactly the same as you in the early days of foiling. Even before Winging started. It would be a bit like a biplane. Maybe call it a bi foil.
The main reason for me was the serious problem of breaching with the early model foils. That is. Just as the large foil gets to the breach, the smaller foil underneath takes over & you are away. But now the longer span high aspect foils seem to have this under control somewhat. So I dropped the idea.
But now as you mentioned it. It may just be the ticket when winging to be able to use a smaller Windwing. The larger foil just underneath the board to help seperate the board from the surface of the water easier. Then the smaller foil to ride on. This would alleviate having to have such narrow unstable long boards.
It wouldn't be hard to design or make if I had the equipment. If so, I would have already done it.
Maybe a large Wing attachment that can be clamped at any height on the mast?
Now that we have talked about it. Watch this space. Lol

People have definitely tried: it www.seabreeze.com.au/forums/Windsurfing/Foiling/Ultralight-wind--5mph-or--4kt--windfoiling-BAF-for-older--Heavy-Dudes--90kg--and-no-pumping
That's just one topic, there are others with slightly different configurations here on Seabreeze.

Does it make sense - unfortunately not becuase you add more drag which negates the benefit. If you want to get going in the lightest breeze, get a big high aspect wing.

Thanks Nikita. Didn't know that until now.
