After 30+ years of windsurfing, finally took the plunge to try winging, and after 4 sessions succeeded in reaching across Wolf Lake on my 120 L "beginner" foil board (schlogging not on foil). Trying to compare learning this sport versus windsurfing a long time ago, here's what seemed to be different.
1. Winging needs more wind to learn the baby steps. It's really hard with less than 15 knots, wing doesn't provide good counterbalance unless it is flying nicely. Unlike windsurfing, there is no rig weight to counterbalance, you have only a flying wing, a fickle yet necessary source of both counterbalance and propulsion. Ultimately I think this issue will be just like windsurfing, adjusting the wing for propulsion and balance will become second nature.
2. So-called "beginner" foil boards, 100-140 liters are really tippy even with the 10 lb keel and foil underneath. The board I got was smack in the middle or even the high volume range for my weight and prior experience (none). Absolutely needed some wing sessions on a big wide SUP (with a center board) to learn to handle the wing before even trying the foil board. Cannot initiate a run already standing on the foil board, too unstable, you have to stand up as you power up.
3. Drifting downwind more of a problem with winging. Due to the greater windspeed needed, and the wind blowing on the floating wing when you are down, you get blown downwind more, more walks of shame. Need to solve this issue, as I want to be able to wing at Greenwood, where suitable flat conditions will commonly be side off-shore. Need to be able to be efficient in positioning gear and starting a run quickly and reliably to minimize downwind drift.
What's not different.
1. Being a beginner is fairly exhausting, falling, climbing back on the board, reorienting the wing is so much work. When I fall windsurfing now, it's a chance to rest, relax, let the wind do the work, pop up and go.
2. Sense of accomplishment as little improvements and discoveries are made is similar to learning windsurfing.
