just need to add strings , or a stick type thing like a boat mast ...i know you could call it ....:)
could at least stick a uni on one end to make it a fun SUP sail for kids, 2 toys in one!
Looks like a good technique to apply to a Windsurfer or other WindSup type board, given the need for a centre board :)
Great vid, it really highlights the accessibility of wind wings and the potential to draw new people into wind sports. That's good for all of us
