It looks very clunky compared to this:

Yep.
Just the foils added

Is it just me or is that thing a giant knife? Free fish fillet machine.

I'm hoping for some real innovation in this area. Getting rid of the massive inflatable leading edge on current wings must be huge for performance. Things like a modular frame with different size and material canopies should be trivial. I suspect the current big companies are not very interested in this though as their current business model is built around releasing new wings every year where the customer has to buy the whole thing in every size. Current manufacturing is also dialed in on the inflatables from kite days. Hopefully some small independent player will invent a superior product and the big brands will be forced to follow

The BRM looks extremely flat and very unstable. I think some sort of tensioned batten will be required.
