I think it's a misunderstanding, my current set, 710cm2, 910 cm2 front wings, 70-75cm fuselages, 2 sails 3.1 and 4.4 m2 covers 7-30 kn. With long fuselages and 8.0 m2 you might take off in 5.5 kn, and front wing could be smaller. But I decided to not to chase 5-6 kn of wind anymore, on small gear too physical and unstable.
also keen to see 4.4 in 7kn :)

Here we go, I was using 2 year old foil there, new one has better glide/ low end btw. Pls ignore 'king' label, Alex gets a bit overboard with things...
Nice vid - cruisey gliding

I wonder how rider weight correlates to sail area required to fly in light wind
I'm guessing to get going in 10 knots on a big board similar to your board in the video
60 kgs 4.4m
70 kgs 4.7m
80 kgs 5.5m
???
I would need 5.5

JJ, I'm 100+kg and I bet I can fly at 10kts true with a 5.2. I can float and ride (float and fly???) in that for sure maybe even less. It's pumping the big front wing that's creating the magic more than the sail. That said, the sails cut matters a lot. Most wave sails are too flat and twisty for light air foiling, hence the shift towards freestyle sails for many. I am dreaming of sails that are tough enough for the surf but shaped tall, tight and perky.
