I'm a little surprised that you are thinking that mass and power have a relationship.
A light kite will fly in less wind, but that doesn't mean it will generate more power. Particularly if they are someone who only flys with a sheet and go technique, in the hands of someone who knows how to generate power by flying it hard they may be able to compensate.

I think other things like cord and aerofoil have more to do with power
Also most wave kites are not known for their bottom end grunt
Now a Aluula Razor would get me interested


A lighter kite has less inertia meaning it can accelerate faster, and needs less lift to hold itself up, and to accelerate itself.....meaning.... more power for you, instead of power to hold itself up.... we are talking about the light wind scenario here where most "normal" weight kites are unuseable unless in gargantuan sizes

I've felt the difference a light weight single strut kites give in light wind, and it is considerably more power than the same sized kite weighing a lot more.......

More power is more power.

The correlation is clear in all aspects of Motorsport,. weight is power. The lighter it is, the faster it accelerates, top speed, etc.

Unless its a light boxcar/ clearly when efficiency will be hindered by design..... maybe like the ocean rodeo

You're right, power usually reserved in just keeping the kite in the air is transferred to the rider with a lighter weight design.
However the standard Roam by design is not a 'grunty' feeling kite like the Crave, Razor etc. (although it has power and I'm usually sized the same or smaller than everyone else)
It is a quick kite and has light bar pressure, smooth power delivery and a smooth pull in loops. Pulling tight pivotal loops it has very small amount of pull. It is a great wave kite.
It is also a pretty efficient kite in light winds but you can't just pull the bar in and go at the bottom end, and the near 100% depower at the bar will feel different for people who are used to a grunty kite.


The Aluula Roam has the same genetic feel, with lighter bar pressure, this builds to a medium feel at the bar when it's at the top of it's wind range.
It doesn't feel grunty as the power is so smooth. It's a very efficient kite in light winds and, like all kites, at the bottom of it's wind range it needs to be flown. The kite is so quick through the air it's easy to generate some power in both strokes and once planing it will find it's sweet spot and settle in the window.
The most impressive aspect for me so far - the wind range 'sweet spot' for this kite is huge, it flies confidentally and perfectly balanced with no luffing, stalling etc in under 10kn and 25+.


I haven't flown the Boxer so I can't compare sorry, and I'm still yet to see the Aluula Flite so I can't say if an Aluula kite with a 'grunty' feel, or more static pull will have such a large usable wind range like the Roam.

Ozone made the 2013 Edge 19 ultralight for light wind Racing.
It had the same weight as the Edge 14
3.7 kgs that is 194 grams pr m2
And that is with 5 struts.
The same as The Roam 10m with 3 struts.
Mine Edge 19 is still alive and I am always the last on a twin tip that has to leave the water if the wind is dropping, I am 114kgs.

I've got A North Dyno 18 meter under the stairs, that I've repaired a gazillion times.... and it's a little like that..... the no wind monster

However - I did fly my mates 15 Meter Mono....... and it pulled like an absolute freaight train.
