Is that a life picture of Troppo on the wall?

Here's quick look at it and hopefully i can get it out on the water tomorrow..

They look very nice :)

Very nice

I've got a new 5.8 Koncept waiting for me in WA for when I get back, should go well with my new red Carbon Art which is also there waiting for me, xmas will be early

Is the clew cut out deeper?

A couple more from yesterday if you are interested.

I saw Chris and Jesper out with their new KA Races yesterday....the first thing I noticed was that they seem tight in the leach...tighter than the 2016?
I like the look of them....imo the colour combo is better than the orange/white. Not surprisingly, the lads were going very well on them...

Hey Craig, surely those 3 GT31's belting you in the melon must hurt in 35+ knots??

Did you use RDM mast? I like the fact the sails can be rigged on both SDM-RDM masts, nice number out of the bag Spotty

Nice going Spotty... new KA toys in time for the wind love it...

I am interested in your reason for such wide harness lines?
Does this help with trim angles

Kind Regards Russ


that sail looks sweet

...few reasons Russ, apart from a bit old school and just how I roll

-Yes helps with making minor trim of sheet in/out, useful on a curved run or changing angle of your run mid way thru due to power/wind strength fluctuations.
-More locked in and braced feel, if they are close together wave/free style your hook/hips will be swingin off a pendulum somewhat.
-Harness lines too long, so spread them apart to shorten drop/depth.
-I'm heavy, so having them close together point loading the boom not a good idea.

Yet to try our euro counterparts crazy super low boom and short lines technique that works for them.

Fantastic tips there Spotty best one I have had in years so I will be looking forward to trying this...

I can see how it will improve the line drop out I get when I go deep off the wind and holding the sweet spot when changing angles as you sail off the wind .

keep up the pro tips mate I think I need them of late

Cheers Russ

I've used a roller instead of hook for past 10+ years and they are so easy to trim the sail compared to a hook and the best part the let you fly when catapulted (release you from harness lines)

Noticeably lighter. Rig feels more alive.

I just wanted to pass on my findings with rigging the 2017 7m KA koncept on a 100% KA 430 RDM mast, to be honest it took me quiet a bit of trial and error to get the sail rigging and feeling really nice. Thanks to Martin and sailquick for helping me as well.

I found that I was rigging the sail with to much downhoaul which was killing the bottom end and found the cams were not stiff enough. I am now rigging the sail with 1 - 2cm less downhaul than what is printed on the sail. I have also been giving it 5cm less out-haul, than what is printed on the sail.

In relation to cams for the RDM mast, i have left the SDM cam in for the top cam and replaced the two bottom cams with RDM cams. I have also placed a single thick spacer between all three cams.

Once i got the tuning right, i am really loving the 7m koncpet. It has plenty of bottom end, rotates so easily but is still stiff when pumping in light winds.

Thanks for the feedback guys and glad you are enjoying the sails....will look into the boom spec print on the 7.0.... sometimes even I make a boo boo

Yep but a typo on an Ai file on the production artwork is all it takes, and by the way have not confirmed it is wrong yet.

If looking at using KA RDM masts (430/400) in the Koncept what is the benefit of the 100% over the 75%?

25%




Oh, OK, I couldn't resit. Sorry.

I have noticed a much bigger difference between 100% and 75-80% in RDM's.

(Not so much at all in SDM's. I actually prefer 70% to 80% SDM's and they are a LOT more durable).

The difference in RDM's is in the weight and feel. The 75% feel 'dead' 'er. The 100% are not much lighter but they 'feel' a lot lighter and livelier. I far prefer 100% RDM's. The other big advantage is that 100% RDM's are VERY much more durable than SDM's. Nothing is unbreakable, but they are much closer. I snapped quite a few 100% SDM's over the years, speed sailing, (and even a few 50% and 75% SDM's as well) but I have never broken a 100% RDM. The only sails I use SDM's in now on are 7m and larger.
I tried the 2017 7.1m Race on a 430 RDM and it didn't set well (best on 460 and I haven't got a 460 RDM). In contrast, the 7M Koncept sets well on a 430 RDM, but it is meant to be set on a 430 anyhow. Last year, I still used my 7m Koncept on SDM as in that size, for me, it's all about bottom end grunt, (it was the largest sail I would normally use) and the sail set a little fuller on my SDM mast.

Oh. The other advantage of Koncepts on RDM is easier and smoother rotation, especially with the new KA RDM cams.
