Having had some thoughts about this thread, but not time till now to comment.
I dont agree the point only is to go out when you can not go out with a waveboard, it is two different disciplines that can no be compared, eventhough most try to do so - meaning "emulate" riding on a surf/waveboard, when hydrofoiling.
THAT does not work well IMO, and is not the right approach.
You can ride waves with small kites, I have a 3.5 m2 I use when windy.
But as Bragnouff and others have said - it often works way better when it is NOT sideshore.
Maybe because you got more options, and in these conditions you DONT try to "just" emulate surfing.
The power from the waves, even the smallest ankle snappers, are extreme and can be felt and used way more than on a surfboard.
You can really notice this if you ride really underpowered and do a full carve so you got no power in the kite when coming out of the carve - but using even a one foot small windwave, can make you foil along no problem even with slack lines for quite some time
Most of us use this often, to be able to keep foiling at this point, till we are up to speed and power from the kite again - OR just enjoy riding without kitepower for a while
Agree a lot with Starsky in his post above btw.
There are some interesting posts about this topic somehow ending up in the other thread about "Surfing with a Kite Hydrofoil" which was about surfing and not kite(foil)surfing.
Without outrunning the wave ?
But we SHOULD be able to do this if we want, the whole point as otherwise we can not do turns on the waveface, nor ride anything but perpendicular to the wave.
That is the same way most ride with a waveboard, eventhough I still will say you should not compared - but here we also ride faster than the waves usually, so we can do turns and ride up or downwind or DTL.
When out in waves, small or big, making foiling 360s up and around in/on the waveface is maybe THE most fun I have ever had, it does not work for me every time no, but when it does, it is like nirvana
You can use a foil to have fun in waves, where a waveboard would be useless, and at least boring, if lower wind or flat waves or onshore etc.
You can use a foil to have fun in waves, at the same conditions where waveboards excel too, that is your choice and you can do one or the other or both.
We were out in bigger waves not that long ago - I started out on my wavefoil with a 5 m2, it was "medium" waves this day, fully sideshore wind, but outside came some huge sets now and then - awesome to ride these, here just carving around having fun on the smaller ones first:
The small wave above wave is ending later on a shallow sandbank, but again, you learn how to keep foiling high (using a 100 cm mast, which I prefer) so you can transition inside the sandbank, or turn over the bank and ride out to deeper water for a "risky" jibe (meaning, where your board might end up on the water surface when you make a bad one).
Some hours later the waves build up a lot (so did the wind btw), and outside the really big sets were truly exhilarating to blast down and around on the faces:
Riding at high speed in front, to ride past the section to get to the clean shoulder
It was great and really exciting.
When you got tumbled around in the whitewater, it was no problem "avoiding" the foil, being an experienced (= old ha haa) waverider (and foiler) so you knew how and where to fall so to speak.
I also went out on my waveboard, having good DTL rides and fun in the steep dumpers
Having had a great day out there with a 5 m2 on foil and an 8 on waveboard:
And yes, our crabs are well sized here in Denmark c",)
The title "Wave Riding Foils, not really waveriding" ??? implies you are stuck on something and can not change and open up for new things.
OR, you have realized it is a new world, different indeed and should not be compared
One thing is for sure, you can utilize the power from the waves way more on a foil than on a waveboard - but it is not relevant for the "Fun" factor.
As said before, hydrofoiling in waves are SOOO different than on a waveboard (luckily) and we have the chance to find new ways of riding and having fun, and can enjoy both foilboards and waveboards.
Whether you prefer a short or a long mast, a small or a big wing - is fully individual and for some depending on conditions on a given day - the point is, it is GREAT FUN
