When you have learned, you can most often (depending on your conditions) walk out till hip/chest deep between sand banks, and get up foiling parallel to the banks, so you can go upwind and conquer the low sand banks and breaking waves and get "out".
Works most often for me, but I use a short 80 cm mast, which gives a lot of benefit for this.
Otherwise, paddling out on your stomach, wingleash on your waist or leg the easiest, can quite often be done.
Indeed, eventhough a kitefoilboard is much smaller, it can be difficult as you have to drag out for a long time in the breaking waves, because of dead onshore winds and a low angle upwind when boarddragging through, so agree, not always easier than a wingfoil.
Everything depends on HOW harsh your conditions are of course
If you are learning, you should not ride in these conditions, as you WILL lose ground the first long time.
