So Slow 13kt minimum for a 540 foil! GS010399

Testing the new F4 Wahoo 540 front wing, 170 rear wing with GP95 mast foil set with integrated fuselage. Riding FMX91 and 9.1 CHS sail in barely enough wind, 6-10 kts with occasional gust to maybe 15kts.
Here we are going super slow... I can't believe the 540 SLALOM wing is still flying in what would barely hold a 1000 wide course racing foil up!
