could you comment on your statement

Can you give me some more infos on that? Is your foil getting less controllable at high speeds?
i will most likely get weak again and push the limit again...
on the foilboard you are constantly in an unstable equilibrium. any impulse you get to your system, you need to compensate. impulses can be: gusts, waves, seaweed, ventilation, under water turbulence when you cross the track of someone else and so on. if the impulse is bigger than you are able to handle, you crash. the faster you go, the shorter is the time you got for your reaction. sometimes you got no time at all. another problem is overreacting. for instance, the impulse lets the board come up, you react in putting more weight on your front foot but it is a wee bit too much, so the board goes down too fast, then you react on that but also too late and too much and the board goes up again and down and up until you crash... resonance disaster.
by the way, don't underestimate the underwater turbulence chop can create. you will be able to go faster in flat water. on the other hand you are able to reach your vmax in way less wind than with the sector so there will be less chop.
all foilboards have a certain vmax above which it is impossible to keep the board in balance even if the impulses are subtle. the vmax depends on the construction of the foil (length of fuselage, size of stabilizer, front foil profile and so on) but also on things like riders weight and obviously on the skill level of the rider.
due to the fact that you will crash when pushing the limit, i am always using a helmet with ear protection and i don't use straps. in the past crashes even in 40+km/h where mostly harmless. sometimes you bounce once on the water surface with you bottom and that's it.
three months ago i had two similar crashes that were not funny at all. i somehow go a rotation impulse when i left the board, i hit the water with my back and the head whip lashed back onto the water. since that time i sometimes felt a little pain in the neck when i moved the head in certain ways. it did not go away even after two months and i was about to make an appointment with an osteopath when i had this session with my twintip and the elf d8. i was practicing hand plant transitions. the first went ok but when i did the second, the kiteloop was to early or my rotation was not fast enough, eighter way, the kiteloop was yanking me out of the straps, me backwards, while flying i was thinking "nooooo, not again!", i hit the water with the back, whip lash... i got the board, started and while i went towards the beach, i was like "wait a minute, it is better now". since then my neck is back to normal again.
you can call me chiropractikiter.
