Hmmm, you might all be completely spot on
But have to say, I have never really understood this ?
Of course backwards as I've learned kitesurfing and hydrofoil before using an indo board thing.
But besides showing how sensitive and difficult it is (which is completely spot on, agree), I can not see any resemblence ?
On an Indo board your "wrong" weight distribution will accelerate hugely - this is not the case when riding a hydrofoil - it is really sensitive yes, but it will not accelerate the same way as if going off balance on an Indo board ?
Forgive me if wrong, but I honestly think it is more about preparing about that hydrofoiling is not just lean back and fly - but way more demanding, especially for the "hidden" muscle memory you can not control with your mind
Sorry if way off, but honestly what I think....
