A 14 m2 kite is NOT that big for hydrofoiling, with 107 kg.
It corresponds to a 10 m2 kite for the average weight, so the 14 m2 would be just fine in 10-12 knots for you Lopi
If you need to ride in say 15 knots, I think a 10 m2 would suit just dandy, when you have mastered that is - for learning a bit bigger kite is needed in 15 knots.
If you want to ride in 8 knots, it is a very different ballgame though, and your 14 m2 "normal" kite can not be used.
Too small for you, and kite also too heavy, it can not hang well in this low wind nomore and will drop in the water way too often, probably even before you get out on the water...
So in this range you unfortunately need special kites, a lot more expensive, probably only light foilkites 15 to 20 m2 can do the job for you.
Where us average weights can get away with light LEI kites, say one or nostruts 12 to 15 m2 in size.
When learning, you will crash the kite a lot when all your focus is on the foil, so if wind is only 10 knots it is difficult to learn, as you probably have to drift ashore to relaunch every time you crash the kite further out, and you need to be further out so it is deep to learn foiling.
Even those with years of experience, crash their kite in 10 knots when they go out for the first time, so for you with less experience it will probably be a very steep hill to get past
Possible most likely, but a challenge indeed
You have to learn in 15 knots IMO, for having a chance to learn without too many "added" obstackles.
