Re: Top speed of a Moses 633 SUP wing combo (the Onda)

Stall is not a function of speed. Stall happens at a certain angle of attack. What is meant above is that at that speed, you need such a high angle of attack to support your weight (minus the kite lift) that this angle of attack is critical - stalls. I assume that gunnar said 82kg meaning no kite s...

So what's the stall speed?
About 6 knots for a 82kg person.

Gunnar's method and video makes the Long Mixer Test clear up to the point of setting Z the same as C -- why? Why even 2x C? Why wouldn't you set Z to the difference it should have been in the line plan?

Because the Z lines shrink at that rate.

Re: Carbon foil cosmetic quality

Most Race foils on the Market are delivered nice and shinny (mold release) which is not really what you are looking for. You will need to sand them to a matte finish to get the most out of them. Also you will usually have a few imperfections and pinholes which will need filling. I have tested a lot ...

Hi

I weight 75 kg and I will use a moses fluente with mw550

Best regards

Fabrizio
Have your learned to foil already? If not, maybe do a course first. After that that combo will be fine. Learning be yourself on the 550 and 91cm Mast from zero, will be difficult.

Re: Line length, gybing and down-looping

Probably the combo of kite not high enough before starting the loop, and initiating the loop before starting to turn the board.

Here is a video that shows the timing. This is on a 9m kite on 10m lines.

Hey Gunnar, nice video. Do you know volume of board? I am looking for a board for strapless foiling that is easy to put on its side.
Sorry. I am not sure about that. If I would have to guess, I would say its about 15L.

Re: WOO 3.0 pre-order

Basically Apple says that you should not be using your Apple Watch for Watersports. Apple Watch Series 1 and Apple Watch (1st generation) are splash and water resistant, but submerging Apple Watch Series 1 and Apple Watch (1st generation) isn't recommended. Apple Watch Series 2 and Apple Watch Serie...

Re: Hydrofoil Videos

Hi Gunnar, Great video, as usual! I have been wondering which board are you riding in your freeride video. Can you compare this board to a Ketos 118, if you have tried it? Thank you, Jaros Hi Jaros, I have ridden one. Besides the fact that the Ketos can only take KF box foils, it is also 2cm less w...
