thank you for showing how fast slalom boards are with respect to a wing! (Get a racing windfoil and it is a different story of course.)
Quite amazing what you get out of these graphs. They showed that upwind angles are significantly better when free riding with a wing than on slalom gear. If you focus on speeds, that's about as meaningful as comparing average speeds for wave sailors at the PWA Cabo Verde 2022 to slalom in Fuerteventura this year.
At most places outside of Oz, where the water is not flat, you'd have to compare free ride fins to foils. That's not really a competition with respect to VMG - the wing wins hands-down. But perhaps the even more relevant issue is how much play time you get. We're on Cape Cod, one of the windiest spots on the US East Coast. This summer, foilers got at least 3 days for every day that windsurfers were on the water - with the added bonus that windfoilers and especially wingers rarely had to go in an change gear, while windsurfers frequently waited for the wind to come up/back, or re-rigged. The one windsurfer that got the most time on the water switched between foil and fin depending on the wind.
A few years ago, windfoiling was slower than finning in many "real world" races, and there were plenty of windsurfers who assumed it would always remain that way. The PWA events in the Canaries this year have put an end to that. Maybe winging will never get quite that fast - going fast is not really where the fun is for most wingers. But I would not bet on it. The GWA wing slalom races are currently held back by the mandatory pump leg, which limits how small the wings can get. Many wingers "automatically" graduate to faster, smaller, higher-aspect wings as they progress. The wing polar plot I had posted was on a 1250 low/medium aspect wing. The same winger would now be on a 725 high aspect wing in the same conditions, which is a few knots faster without even trying to go faster. From what I have seen, that's a pretty typical story. One thing winging may have going for it in the long run is "nicer" crashes. A full-speed, hooked in catapult on the fin, or when the foil comes out of the water in windfoiling, can be quite nasty and painful. Those crunching sounds my neck makes seem to get worse after each bad fin catapult. In contrast, many wing crashes are quite harmless in comparison. Sometimes, they are pure fun, when you keep flying with the wing in your hands long after your feet left the board.
