bonus:

Hans is tall, he is wearing a waist harness and he has set his boom below the height of his shoulders, hence the short lines

On The Brace, but the pic is from the speed trench.

That's impressive!

That's interesting. Super low boom too.

That looks really odd. Maybe his boom slipped.

In the "speed" edition of the pommy windsurf mag they have a great section on the big hitters at Luderitz. Hans Kreisel is apparently one of the new breed of sailors who are using low booms, very short lines and waist harnesses. Rig very upright and on the power all the time. Its a great read.
Anders, Antoine etc are all doing the mid to high boom and 30-32" lines and seat harnesses.
Hans setup must work, his speeds are bull****!!!!!

I'd guess it gives more drive through the front foot so you can use a smaller fin and go deeper.

Bigger wipeouts too I guess.


Some biiig sails in the video.

Low boom = control. He probably had enough wind to not need the early planing of a hi boom

I'd not criticise the setup of somebody who just did 54kn...?

Ahh, the good old days of short lines....just wait till he discovers the chest harness, then he will really let loose...

AKA the Mistral Nick method.

I have short harness lines, low boom and use a waist harness and can only do 24 kn.

He must be doing something else!

Hes on a pryde evo. What do you expect!

Finally, everyone on the bay might stop telling me to raise my boom!

^Yeah, more downhaul though.

What's the upside of the waist harness? Just the higher hook? Then why not just use a harness like the surf seat? Is it just fashion? I see the rsx sailors sticking with the seat harnesses fwiw...

I got an answer about the low boom and harness lines from another speed surfer who knows Hans. He has the boom very low, especially considering that he is quite tall, so that he can transfer as much weight as possible onto the sail and mast foot. You can almost see how he is pushing down hard on the boom. He uses this setup practically all the time when speedsurfing, even when conditions are harsh. Seeing his consistent results (he gets close to 50 knots almost every month!), a few other windsurfers have started to copy his setup; most of them raise the boom height to more normal positions, though, when conditions get tough.
