Prone foil: how to limit "breaching" (sudden loss of lift when too high on the mast)

Hello,

Let’s first define what I mean by “breaching” because I’m not sure it’s the correct term.

When proning (waves, surf), getting too high on the mast and suddenly losing all lift, and collapsing, often resulting in falling down in a pretty uncontrolled way.

Sometimes happens when I’m going too fast with decent waves.

But, “surprisingly”, happening even more with super small waves.
Because waves are small, to exploit their small energy, I need to be high on the mast, and to place mini pumps here and there during the wave, when linking turns to get going.
As I’m working much close to the surface, I tend to breach.

It’s not helping that small conditions usually come with crystal clear water, which makes very difficult to assess the height on the mast. I sometimes breach and fall while pumping on absolutely flat sections between two waves…

This is the event I find the most dangerous in foiling.

Is there any specific technic or tips to limit these events ?

FYI, I am riding Code 980s, and I am a mediocre foiler.

Cheers

I too am a mediocre foiler and last year got a nice clip of myself with a classic foil breach - see at 6 seconds.

Classic Foil Breach

Our coaches said to think of your height on mast like a seesaw - you want to be low on your mast as you initiate turns and the power from the turn will bring you higher on the mast. This helped me a lot. If you watch Adam B on some of his harder carves the side of his board literally skims the water while he carves so he never breaches.

Thanks, that’s a super good example.
As carving increases the lift, it makes sense to not enter a turn already too high on the mast.

But you need to be going at high speed with good swell to ride low on the mast without stalling.

Enter a turn nose down was the advice I got when I was learning.

For smaller swell with low energy I find that it really helps to constantly be turning to generate more speed vs. staying as high on mast as possible and pumping or going straight. Might be worth trying that?

Another good example of James Casey, very subtle breach at low speed, impossible to recover.

he almost recovered it, they are much more recoverable than you’d expect once you start to anticipate it and build the correct reflexes

you can start to sense the foil getting close to breach, that is critical

fwiw, what is happening here if not obvious, is that your foil is “breaching” the surface of the water, resulting in the loss of lift and drop. This can happen either on one or both sides. here is a video

The way to think of it is like a drift in a car. From a beginner perspective, a car losing grips means you will certainly crash, however we know this is not necessarily the case. If you anticipate it, and react correctly, you can “catch” the drift and control it.

The same applies to a breach

Oh man I wish I could see it as a fun event like drifting in a car.

For the meantime I see it as what prevents me from riding more aggressively, it’s a psychological lock.

get some straps and practice ollies and jumping on the foil, this wil give you the feeling of a ventilated foil hitting the water, and the reattachment of flow onto the foil, this way you develop the feeling

That’s an practice I never thought about.
I would try it if I had aboard with straps.

Worth it I think, I’m going to get a board with straps to get rad, clearly a useful way to get comfortable

Agree with this. When on a wave, rather keep the foil moving (which creates lift) by turning with a lower mast position than going straight or (worse) pumping while on the wave.

For pumping, being high on the mast is a good problem to have. I find the sudden speed/efficiency burst is a good indicator that im close to breaching. For a quick reset i lift back leg instead of trying to lean forward. Lifting back leg immediately puts pressure on the nose as apposed to bending knees/body forward that takes a split second longer.
Also, when that high on the mast, i stop listening the “experts” that tell you to hop instead of stomp. If you take your weight off the board at that height you will breach. The times I’ve managed to recover from a near breach, involved either just gliding with front foot pressure (back leg lifted), or light stomping heals with level board deck that creates forward drive and lowers the mast. 2c. Works for me.

Yeah, I’m making tiny little maintenance pumps when I’m high on the mast. Nothing else works. But the good part is it takes very little energy when in that zone so all it takes is little pumpy pumps
