Thanks to James Harvey who kindly let me demo the new Flysurfer Boost 13m.
Out of the bag a quality looking bit of kit rolls out on the sand, as I'm a lazy bugger out comes the electric pump, there is a pocket attached to the centre strut containing an adapter to fit the larger size nozzle allowing correct fitment. Inflation reveals the Boost (I believe the colour combinations denote the kite sizes with flysurfer so green, purple, white and black for the 13m, 7m has the same colours but in different combination). As I was using a foil board I decided to use my ozone race bar as the standard bar that comes with the boost is for free riding and the trim/de-power are a bit of a reach, however you can order the Boost with the Flysurfer Sonic race bar so James tells me. Wind conditions for Ocean Reef were…

3:30 11 - 14 knts
3:00 10 - 12 knts
2:30 13 - 15 knts
2:00 13 - 17 knts
1:30 12 - 15 knts

So averaged 11.8 kts S
I am comparing the Boost here to my 13m Edge and for racing with a foil, I will leave EPPO to cover the jumping and freestyle merits of the Boost.
Well the boost has no lack of grunt and certainly easily matches the Edge even in these lighter conditions; I recorded a 25 knot run with ease so double the wind speed. Up wind offered no disappointment the Boost pushes for the edge of the window with a constant pull and very smooth in its power delivery through the turns, this where the current Ozone Edge and the Flysurfer Boost differ IMO the Boost is quicker and crisper through the turns. Downwind on the foil with no de-power the Boost drifts nicely and easy to control with one hand allowing you to go as deep as you dare and keep contact with the rear lines. Over all I like the Boost for racing with a foil board and would like to try the smaller sizes 7m and 9m in stronger with conditions as this is where the foil kites are more problematic and LEI seem to be more stable. The Flysurfer bar and lines are high quality and IMO better than the Ozone offering although I have not tried the latest Ozone bar with softer bar ends as yet.

OK decided to test the relaunch of the Flysurfer Boost 13m today, relaunch is always important but not something we fully appreciate until we find ourselves swimming 400m off shore. Well many relaunch tests seem to be carried out in chest deep water with traction gained from contact with the sand/bottom, in my mind this is not a real test and it should be carried out in deep water suffice to say.
Now I've body dragged out to 15 foot plus of water and flown the Boost to the edge of the window and rolled her in (sorry James but have to test the relaunch means she’s got to get wet!), now the Boost wants to sit on its wing tip, not what I want to test, so I have to pull hard on the port tip rear line to force the kite leading edge down, this is not easy as the Boost is resistant to leaving the edge of the window (good sign she want to relaunch off the tip), having persuaded her to sit nose down/leading edge down, now I can test the reverse launch of this LEI kite, so I pull on both rear lines and the kite rises off the water about 200-300 mm and turns up onto a wing tip opposite too which ever you put more pressure on and she’s away back in the air. I have reverse launched many times using a foil kite but never found LEI kites willing to reverse launch so this is a great addition to this aspect of our sport well done Flysurfer.
Wind at Ocean Reef was reported
2:00 13 -16 knts

... Hey Pilotpete, nice little review.

I have a couple questions, actually maybe a few more than a couple if you don't mind. I know you only tried it in lightish winds on a foil board but I think you might be able to tell me:

Did you find you needed to get a bit of speed before the Boost got its power and did the power remain steady as your speed increased or decreased?

Did the bar pressure and turning pressure change with the power increasing or decreasing? Did it behave like the Edge?

Do you get any power spikes or power changes from an upstroke or downstroke while sineing the kite?

Do you reckon the Boost is a more freeride than the Edge but without it being too freeride like the Infinity/Fatlady type of kites?

Is the steering reasonably direct or is there any inherent "bridle kite" feel or lack of a better word, spongey?

Thanks and cheers,

Robbie

OK Robbie I will try to give some indication to your questions best I can.
The Edge is my most used kite of recent times in 7,8,10,13 and 19m, so comparisons relate mainly to this kite.

"Did you find you needed to get a bit of speed before the Boost got its power and did the power remain steady as your speed increased or decreased?"
The Boost had good power/grunt at the low end and built constantly as speed increased probably due to its higher AR it did remain steady through out.

"Do you get any power spikes or power changes from an upstroke or down-stroke while signing the kite?"
Found it had steady power on the up stroke but more aggressive pull on the down-stroke didn't feel spikes as such.

"Do you reckon the Boost is a more freeride than the Edge but without it being too freeride like the Infinity/Fatlady type of kites?"
OK not flown the Fatlady or the Infinity so cant judge against these kites but would say the Boost has a better freeride application than the edge, it will turn better and drift better than the Edge IMO (jumping see what EPPO has to say he now has the Boost to test).

"Is the steering reasonably direct or is there any inherent "bridle kite" feel or lack of a better word, spongey?"
Found the steering to be direct but did feel it a little spongey if I aggressively fully sheeted out, this was only momentarily as the kite re-tensions the back lines and this may have been more to do with my lack of time/timing on this kite to be fair.

Hope this helps

There will be a couple of riders who boost better than me to try as well. Let ya know the hang for old school tragic board offs As that's me done and dusted

wind permitting...it's hit and miss right now.

Hey Robbie,

Hopefully Pete's answers have helped you.

You may not have seen this video as it was only posted a couple of days ago, but it may help you also. You can watch here or over on YT in HD too.

It's been well put together for a video review. From watching the video (only, I've not flown the kite) I would agree with Pete that it does seem to be less 'single minded' than the Edge also. Def worth a demo - but there's your conundrum..

I don't mean to ask this stupid question, but does the Boost come with a User Guide that we could check out (PDF?). Looking at that video, it looks like they've imprinted the entire guide on the kite itself!

... interesting, thanks! If an 18m is ever being past around, fling it to Darwin!
