I would appreciate if anyone could advise if a Naish S26 wing hover board would be suitable for kite foiling. I am 95kg and considering buying the 40litre due to its superior strength compared to hover lite & hover cross boards, and increased buoyancy.
132x53x8cm apparently which would be huge for kite foiling, particularly the width and depth. You could use it if you want to save money and have a smaller prone foiling board as well, but it won't be great in the long run. Most of the time a dedicated board for each discipline is better, if you can afford it.
You don't need bouyancy for kite foiling. The kite provides that.
