Still struggling to get up on my foil. Hoping this is the year.

Good luck to you! As they say, the bigger the effort, the greater the reward! I have to agree here.
One thing that is not to underestimate, is how appropriate your equipment is. Learning to windfoil on cobbled up equipment - wrong size foil, mast, board, etc. - makes it more difficult.

How much wind did you have that day. Must has been pretty lite to rig a 7.2 with a foil.

I would think likely 12 knots (didn’t had to pump much) with a few gusts in the 15-18 knots.
I’m 187lb so a 7.2 sail is not so big for me.

I started foiling recently. Yesterday I was on 5.3 and foil. I was over powered at times, but I would have been under powered if I was windsurfing.

Cool! Great to hear!
I’m also usually two sail size down on windsurf foiling than I am on a fin windsurfing. Yesterday I was windfoiling too on a 6.2 and was overpowered at times. I just dump the excess power by sheeting out.
I’m starting to make a few turns (jibes) and this has made a huge difference in my enjoyment of my windfoiling sessions. Not having to fall every time saves me tons of energy and I can start moving upwind and downwind more efficiently. The only issue is that it took me a while to learn. It was utterly frustrating to me. But putting the hours and trying over and over is the way to go unfortunately.
I now only windfoil in light wind (10-13kn). I can pump onto the foil in as little as 8-9kn but it’s a lot of work! If I see established wind at or above 15kn, I’ll rig my 8.2 and will do a fin session. I used to sail a large lightwind board on an 55cm fin and a big 9.4 sail. Since I’m doing windfoiling, it’s been years since I used it: too taxing physically for me!
Cheers!
