My wife switched fully from windfoiling to winging. She'll sell her windfoil gear, and is thinking about selling her freestyle gear. She still enjoys windsurfing on slalom gear when the conditions are right.
I have tried winging, and got up on the foil a few times. But while I wanted to try windfoiling again after the first few sessions, even though the flying times were extremely short and the crashes big, I did not get the same feeling with the wing. I'll stick with windfoiling for now.
Watching others at Bird Island in Corpus Christi in the last few weeks, I have seen that some of the supposed weaknesses of wingfoiling are just myths, probably arising from watching beginners.
1.
Low end: The low end of a typical wing setup is
at least comparable to a freeride foil setup. There were several sessions where my wife was perfectly happy on her 5.4 m wing, while I was mostly slogging with a 6.5 m sail. On freeride windsurf gear, we'd be about evenly powered on 5.4 and 6.5. On slalom gear, she'd be on a 5.6 when I am on 6.3.
2.
Top speed: The few times I was able to convince my wife to put a GPS on, her top speeds were pretty close to my top speeds with a sail on the same foil. Another winger who was on a Moses wing (not sure which one) was definitely faster than all the windfoilers out there, who mostly were on Slingshot foils. His skills were decent, but not outstanding. Apparently, wingers are now going towards high aspect foils, too. But they need some basic winging skills first. Sounds familiar?
3.
Speed in turns: Jibing on a foil is fun because you can keep so much speed. On a slapper, keeping 50% of your speed is very good; windfoiling, 60% is pretty easy, and 70% is possible. But after watching some windfoilers and some wingers learn, learning to foil jibe seems definitely easier with a wing. I've seen several wingers foil through most of their jibes within a few weeks of starting to work on it. For most windfoilers I watched, foiling though takes a lot longer (even if they learn much quicker than I do

). On a good day, I keep about 60-65% of my speed in my better wind foil jibes, and occasionally 70%. With the wing, my wife gets about 70% in most of her better foil jibes. And tacks? Maybe Balz can foil through duck tacks, but everyone else sets the board onto the water in tacks. Foiling through tacks on a wing is harder than jibing, but can be learned within a few months. I've seen it happen.
That said, I have revised my opinion about the range of winging vs. windfoiling a bit. When my wife had only one wing, she'd be perfectly happy with it in 12 to 30 knots. Now that she has three, and usually one that is her favorite, she has gotten a lot pickier, and even started complaining about the wind being "to strong" when it gusts above 20 knots and she wants to use her big (5.4) wing. I have seen other wingers switch wings, too, when the wind changed a bit, and complain about wind quality during sessions where I was perfectly fine with one sail. Being on a big, forgiving windfoil board that can either be sailed "stand on top" style with a small, barely powered sail, or hanging out with a nicely powered sail, can give you a range that's at least comparable to what wingers have.
