We need to be careful not to be misleading with low end numbers. Dsurf is pretty light and likely quite skilled. Host is also quite light and has super human skills. Their low end numbers are not to be used as general bench marks. Rider weight, skill level, front wing size, and a host of lesser variable make for a pretty wide range.

I am average weight 77-80 kg and generally don't enjoy riding the Peaks underpowered. I want to be in the sweet spot. I can "just" get up and going on the 5m in 10 knots, but generally don't! I'm happiest when I don't "need" to loop the kite for waterstart and can start straight up to foil (when I get it right). In 14 knots when Dsurf is ok on the 3m, I'm still stoked on the 5m, and really only rig down to the 4 once its well and truly 15 knots or more.

I have read this entire thread and have a full season on the 5, 4 and 3. Have played with line length and have decent skill.

I am confident in these recommendations.

Average weight rider (75kg) , standard 21m lines, 1000-1200 cm2 wing, minimal skill.

5m: 12 knot start
4m: 16 knot start
3m: 20 knot start

With practice you can pull off lower start for the smaller two, but those are simple right out of the bag first session recommendations that can be scaled up or down depending on your weight.

These are very correct values for the "easy" surf yes, not absolute low end if skilled, but one should not take a size out in less than above (if average weight) on purpose no.

Can add, for the average weight - and "easy"

11 m2: 8-9 knot start on longest lines
8 m2: 9 knot start on longer lines
6 m2: 10-11 knot start
5 m2: 12 knot start
4 m2: 16 knot start
3 m2: 20 knot start

So as one can see, the bigger sizes moves slower and slower towards lower wind.

And the breaking deal happens from 6 to 8, as 3-4-5-6 are awesome (great does not cover), 8-11-13 are nothing special, apart from the ability to hang way longer when wind drops, than any other kite I think, so you hardly never get a swim.
And the ease and speed of rigging and packing - nothing can beat these :rollgrin:

As said, max lowend depends on many things....
I ride an 8 from 8 knots, the 6 from 9 knots, the 5 sometimes down to 10 knots, and a 4 down to 14 knots, and the 3 CAN be flown in 16-17 knots even though below its sweetspot, but this is simply individual what one likes and are able to.
And when I had the 11, I am pretty sure it was just around 7 knots lowend.

Still, never trust these low end wind ranges, not from me either - impossible to measure and share :wink:

I agree with this. I am 90 kg and after a few months riding my preference is now:

8m: 10 to 14 knots
5m: 14 to 18 knots
4m: 18 to 22 knots
3m: 22 to 26 knots

Just received my 5m Peak. It's not surprising they're "cheap" - there's nothing to them! You're not getting a lot of "stuff" for your money! The package is tiny: perhaps half the size of my my 3.5 Boxer & 1/3 the size of a 9m 3 strut. Would make a huge difference in flying with kites. Out of interest, I took the time to weigh my kites fairly carefully:

0.85 Kg Peak 5m
1.43 Kg Boxer 3.5m
1.95 Kg Cabo 5m
2.17 Kg Cabo 6m
2.30 Kg Cabo 8m
2.75 Kg Cabo 9m
3.31 Kg Cabo 11m

Never has the saying "Less is more" made more sense :thumb:

You just measured travel weight? Which is fine if you were interested on that.

For riding/flying mass pump them to your flying psi and also measure air mass inside the kite. Might be upto +500g depending on kite size, bladder diameter, number of struts and pressure.

Yeah - I'm not a mechanical engineer, so I won't be doing that! :-?

I think there's a simple, indisputable fact: the single skin Peaks are a lot lighter than LEI kites, or even closed cell foil kites of similar power. Very useful for travel & understandable that it would significantly effect their foiling performance.

This flywheel hypothesis should be easy to test with the prior generation Ozone/Flysurfer kites where there was an option for regular or UL cloth.

It's easy to assume the UL stays aloft in less winds. I believe FS did a test also demonstrating faster turning with Deluxe. The Kitefinder guys did a back to back on Chrono Regular and Ultralight and liked the UL. But does the heavier kite provide a more powerful impulse to water start?

yes we do. light weight . It is usually very expensive to make a light weight durable kite. it is "in the package", just not visible :D

This is freedom. Does anyone has a better video?

I'd go with the "less is more" position. I'm not sure light weight is inherently expensive ... except in Aluula. Foiling has opened up new criteria for optimal kite characteristics - Flysurfer seems to have stumbled across this almost accidentally, with the Peak4s.
