for kite foilers mostly, do not mention wndfoiling, and has to be relatively slow.
The improved turning they claim my intrest some of us. By now we all seem to understand that long fuses don't turn as well as shorter ones. This one has no fuse.
Low aspect ratio, awkward corners in the outline, strange tapering, foil section with a lot of reflex. Many aero-modelers have built nicer, probably higher performing flying wings in the past.
