Hi Lorgra,
Learning foiling is super easy and the progression is very fast. The right foil, coupled with a 30 minute boat session and maybe 1hr of coaching and you should be up and riding in just a few sessions. We get most people up and on the foil in the first 30 minutes behind the boat. This 30 minutes is all you need to understand the balance and foot pressure needed to foil.
A short mast usually borrowed from a reputable shop

will get you up safely in your first hour with the kite. From there its just practice and practice.
Progression steps
30 minutes Boat - 15" mast and large board with big high lift wing
You may move on to the 24" mast if you "get it" quickly in the same boat session.
60 minutes with kite, 24" mast and smaller wing with an instructor with radios.
In all, 90 minutes coaching with all the right gear to make it easy, safe and fun.
Next step is to get your gear.
Use a low volume board with a single, loose, front strap. Use a light weight kite so you can take advantage of light winds.
Once you can ride competently without touching down or breaching, lose the front strap in place of two front straps. This will allow you to learn to gybe and tack properly.
Accept the fact that you have no references or experience in foiling at the beginning and don't try to apply knowledge you have to it. Save yourself the pain and prolonged noob stage with the 90 minutes of coaching and avoid all that. Get a helmet and maybe an impact vest, wear a wetsuit.
Our store offers free foiling lessons with a foil purchase. so it won't even cost you anything for the lessons.
