Speed is your friend, go faster and you just hop from top to top smoothing it out. Just got to be brave.
the downside is when it does go wrong the crashes are much more spectacular.

Been wondering the same myself. This clip here at 3:45 is the best I've felt on my 145 Blast, verging on overpowered. The other tack lined up poorly with the swells, which were 1-2 fr and causing me to slam around or go flying. I think there's trimming that would help without downsizing my board. 8.0 with 43cm fin. Maybe push the mast base back further? Straps are already far outboard as aft as they can go. I don't get a lot of time on the water like this vs foiling.

Is it on a particular run?
A particular angle?
With a particular board?
Anybody else with the issue on your spot?
Is it hurting your speed? Planing? Knees?

it's the technique for sure! I haven't mastered it yet but I once did it right and my slalom board felt like night and day difference.

what I did: pushed up with front leg like kicking a football and pushing down with back leg like trying to tear board apart.

the thing is that later after that I haven't been able to do this again. it's like i only managed to do it for about 10m and then it was the end of the lane.

I'm sure this year I'll figure it out. It's possible that I also pushed the sail towards the fin but I'm not sure.

the gear was: manta 98L vapor 5.5 and 31cm fin (now switched to 33cm but keeping the 31cm).

Have you spoken to the local sailors who are blasting over the chop and asked them for advice? They can see what you sail like far better than words will describe.

Thanks for the replies, I'll attach my clew view today with my go pro and report back with a vid.

Try raising your boom and moving your mast foot back in 2 cm increments (one at a time) untill you feel the board fly off the fin.

Its funny, that in 15 with gusts to 20+ knots I will skip along the top of the chop or waves when close to overpowered on the foil, get too high in those conditions and it gets harder to recover from a gust.

May I may the comment that you have to be very "active".

You can't really rely on sitting back and riding the tail.

You have to be constantly working your legs to absorb the bumps and fill in the troughs and so keep the board on the water. Soft knees and use your body like a suspension system (springs and also shocks) to absorb the chop when the board wants to jump whilst also extending back out to keep the board on the water, but constantly doing it.

It is maybe easier when you have a nice steady wind and are fully powered up as then you don't have to think about constantly working the sail as well.

Maybe try to make it feel like your head must remain at exactly the same elevation by constantly working your knees and ankles (and hips and arms). For technique practice try hitting some small waves or white water as fast as you can - but absorb everything so you don't jump. Now you just have to do the same thing but 30 times a second.

I find a smaller, lighter, narrower board and single fin makes it much easier to use my ankles (and then knees) to do a lot of the work rather than having to use the whole body - but either way the aim is for you to be in control by being in control rather than sitting back and taking whatever it gives you.

Get aggressive, get active - but stay chilled out and not angry with it all.

This guy is pretty good at going fast in chop:

Boy, that is a rough ride!, when I windsurfed on my local bay, out of the N it was pretty flat, but from the S could get big waves, so I would plow through the waves going out and then turn around and drop into a wave trough and shoot down it, was like glass. Guess that is why I foil now.

Are the conditions in Robby's video the same as Orange Whip's ">20 knots means sizeable swell on the full tide and serious chop. I usually wait until the tide runs out and flattens the surface before I go out"?
Going on a down winder like Robby is one way of dealing with chop as you are going over the back of swell, except when you come inside and head out again to do some jumps. Doing figure 8 sailing and you are going to be hitting steeper sections, even if you try to pick your way through it.
The difference between Robby's kit and Orange Whip's is? We dont know, we werent told.

Well, we know Naish can go fast in heavy ocean swell and chop, just watch Fast Forward or any vid of him sailing 25 knots and jumping out off Maleakahana Beach on Oahu.
But h in the vids, he's mostly hooked in.

I assume this is probably a good tip. I have revisited all the basic Guy Cribb tip sheets, some of them really old. I've become very complacent with some of the basics when I look at his tips. First one I need to spruce up on is tightening my seat harness and getting it back down low where it belongs to maximise MFP.

It is a good tip, but its only half the story. Not staying sheeted in is where you'll start to have a bad time. An open sail lets the nose up, a sheeted in sail keeps it down.

tuning then sheeting in lets you find that skipping off wave tops feeling.

as a side note, this robbie naish video shows his legs from a good angle where you can see the front is extended and back bent and he is leaning back. I have seen all other experienced windsurfers standing like this but I can never seem to do this because no matter which board Im on trying to lean back and bending back leg always seems to result in going upwind for me. I always have to keep loads of pressure on the back leg / fin to feel comfortable resulting in both legs straight and hanging out the side stance rather than leaning back a little and having a proper stance and I've never been able to get faster than 25kt no matter what conditions or rig im riding, never been able to correct this no matter what I try. I need to work this out i think before i will go faster, any ideas?
