Tried looking for this - but could not find anyone else having this problem. I had about 7-8 kitefoiling sessions so far (after about 30 days (1-2 hours per day only due to knee recovery/surgery) of directional surboard this year - and 2 years (around 40 days per year) on a twintip) but whenever I breach/or jump and then come down the nose of my board simply gets stuck so I fly off forwards.. I sometimes can prevent it by lots of backfoot pressure quickly after re-entering the water - which just gives me a very hard landing then - but mostly nose goes in water and I fly off.
Is this a board problem? I tried a board from a friend (very long but very flexible low volume board) and that board would just dive in 10-30cm flex, and then go up again. I know I have pretty shitty equipment as I just bought a used hydroifl board for 400€ (the full set) and in Cyprus kitefoiling is not very common so had to take what I could get - which is a Dutone Speedster Combo foil on a Airush Core v2 Foil 145x47cm (high volume and pretty big) board. Mast is 90cm.
I think it's quite a good setup for the first few days learning, but not really good for anything more? At around 30-35km/h the foil gets very unstable/vibrates so it's not much fun trying to go full speed even at 15 knots of wind only. And yeah landings/landings from breaching suck even more with my problem. Do I need to change gear or are there ways to learn to handle it? I guess both the board and the foil are rubbish? The speedster foil is beginner friendly, but as it's so smal are - with high lift - when landing a jump it will not give a nice landing vs a foil with bigger wings that produce the same lift. As it's so soft it doesn't work for high speed riding either. As kite I either use 8m or 10.5m RRD Religion MK7, or 12m Reeding Supermodel v2. Wind 10-20knots (none of my kites is relaunchable swimming below 10 knots - so I cannot go if lower than 10). We don't get nice waves except for storm days, so it's little choppy in light winds to very choppy most of the time (if above 20knots I take the surfboard)
I had a knee cartilage surgery last November (8cm of cartilage implanted) so don't to just try what happens if I force the board on entry as I 'm afraid I will then hurt my knee again. That's the reason this season I didn't use yet my twintip - as on a twintip for me it's all about boosting, and have to wait for next year to do that again. But yeah some smaller jumps on the hydrofoil my knee should be able to take if the board isn't getting stuck on touchdown. Or is this common for high volume boards? I'm not good yet on the hydrofil, happy if I can link some gybes together, still do footswitch in taxi, and haven't even tried a tack yet (did manage ski stance quite easily, that's also the only way for me to switch feet without taxi).
