Slalom/Speed...

The Koncept is astonishing people!

This no compromise, high performance range has received exceptional praise from very excited sailors.

We have needed 5 months to develop, test and optimise each size so they have been a long wait.

The Koncept will appeal to those who want performance with no limits.

The 5.0, optimized for speed sailing, is now ready after a very extensive analysis of all fast sails we have on record.
The speed orientation of this size means the sail is slightly different to the other Koncepts:
- lower foot
- lower aspect !
- clew is above #6 batten
- foot batten angled up at front
- lower angles on all battens
- head slightly lower
- relatively wider luff

What riders say about this sail:

Peter Weitenberg, Holland:
Just sailed the 5.0, what a great sail is that! I had a GPS top of 72 km/h (38.9kt). Rigged on a North Viper 60 400 mast, it looks really good!

I just got back from running the 5.0 at S.P: Holy S**T what a sail. Love it. A new personal best today of 37.6. Thank you, its a beautiful, fast sail. Bring on SPEEDWEEK.

The new KA 5.0 Koncept was sensational. I thought Mal would be a bit underpowered on it but he was still pulling 38's and 39's all day on his Slalom Board.

A fun day sailing. My hand foiled fin worked well with the new KA 5.0 Koncept even in light winds. At times there was not enough to get going, but once underway it would consistently pull 38's in wind at times barely 20 knots. The sail seemed to revel in going fast, particularly at tight angles to the wind. Sensational!

After KAOS and Kontrol, (finally) my Koncepts arrived. The wind was sideshore 18 to 26 knots and the guys were ripping on their 5.3 . 5.7 m2 wavestuff. I was tempted to do exactly that, but I just had to find out about the Koncept! Was it really that special? Well, I hooked in................ and never stopped for another 5 hours. This sail does its work so effortlessly that it just deceives you: it is truly unbelievably fast and stable. And there is more: because of it's great lift and easy camber rotation it is a great WAVETOOL for very high and long jumping and high speed racegybing on your slalom- or freeride board. I think the Koncept will eventually be regarded and recognized as a milestone in windsurfing.

What a astonishing sail is the 6.6 KA Koncept. I was surfing in marginal conditions with a 120 liter board and the 6.6 KA Koncept. It was a great pleasure to windsurf, with most riders on 7.2 to 8.5 sails. Two other riders used it: a 150 lb guy and a 210 lb guy - they had only good words about the sail. Cool stuff. Wind was around 10 to 13 miles and gust 13 to 17 miles.

This was the first time I could compare the Koncepts against other manufacturers speed oriented sails. I can tell you the Koncept is much easier to use than most other sails. If there was a competition in rigging, sailing 20 kilometers and derigging, I could be at my 5th beer by the time number 2 finishes. ( and I'm a slow drinker ) Did some tuning for the PSL event, had a great time and did 42 knots on GPS with the 6.6 Koncept on a tiny slalom board.

Tony Lorenz: Jan 2005
Used the 5.8 at Cairn Curran in central Victoria. Gusty NW to about 30kts, choppy with some smooth protected areas. This feels just like the 6.6 with even more control. Anyone who uses freeride boards and doesn't have these two sails are seriously missing out. Just two sails to cover 12 to 30+kts has got to be the go.

Tony Lorenz:
I had my Koncept going all Saturday (March 20 2004) at Sandy Point (Victoria, Australia) on my Sonic.
It kicked arse. As wind increased, so did the speed difference with others. Talk about closing the gap, how does resting sail foot on back toes sound. Wind was up and down with strong fronts coming through, never altered a thing, the sail just took it all. draught stayed put.

Andrew Daff, Sandy Point, Victoria:
Holy COW!! You are either very arsey or a very good designer!! ;)
Sailed 6.6 late this arvo in 20-25 kts wsw. Wasn't sure if it was too strong for the sail. No way! Could have handled more, easy.
I wasn't too sure as I rigged the sail if the stability would be there. I was wondering if there was enough
luff curve. I downhauled it pretty far and outhauled to (as I measured later) the exact length printed on the sail (195cm). After an hour or so the wind faded a bit to 15-20k with pretty bad holes up the northern end. I let the outhaul out a centimeter and it still felt really good. I little more backhandy in the gusts coming upwind but still really good. No worries pumping onto the plane after jibing in a hole. Pumps really well! Good bottom end!
You seem to have hit it spot on.

Tony Salmons, Melbourne:
That is unbelievable. It so fast and stable!! I HAVE to have one!

Peter Cleary, Melbourne:
That is the best sail I have ever used. It does not 'depower' or overpower. It just seems to always have the right power. It has the best of a no cam sail and the best of a cammed sail all in one package.
