What is the sail that you rig after the KA?

It depends.Often in a NE the wind goes straight to over 20kts so I rig my 5m Sailworks..If it picks up a little & is consistently 15 - 20kts I'd rig my old North Voodoo 5.7m but its died & I think I'm after a 5.8m KA kult to replace it..

It is nice to have sails from the same company, it can make rigging less complicated.

Dunno, but give you an idea I have a KA 6.4 Kult and I'd use it in the wind range around 18-25knots and I'm around 30kg+ more than you.[8&x29;]

However, being a Koncept, and if the conditions were perfectly flat, it's 20+ knots and you want to set a PB I reckon you can hold it till your eyelids start flapping against your forehead.[;&x29;]

I think you have the skill to do it Sue.

Will the 6.6 get you planing in 5 knots Sue? How is it for waterstarting?

6.6hp yamaha maybe

Would a sail like that be designed for 18kts + so a lightweight that has to change down as it enters its designed wind range wouldn't get to feel the real benefits ? [}:)]Or it doesn't matter what your weight is?

Have you considered asking a sail designer that question, like the guys at KA (co-designer Martin Love or head designer AMAC) or even Ben Severne? Sure you would get an informative answer from the people in the know!

In well powered conditions I have found that cammed sails (like the Koncept that I used to have and the Loft Blade that I currently use) that can rig on a skinny mast are much more forgiving at the top end. I am 78kg and am using a 7m from 15-25+.

The Loft Blade comes with both sets of cams and I have it rigged on a powerex 85% rdm. For the Koncept you will need to buy additional cams. In both cases the sail breathes when a gust hits rather than lifting you allowing you to carry a bigger sail to get you through the lulls.

I've often been thinking of the riderweight vs saildesign-target weight.
I do slalom racing, and its an established fact that most of the fast guys are big guys. some fit some just with a slight 'weight advantage'.what is the key to their dominanse? Their advantage in weight,should turn on them in lighter winds an lulls? Us smaller(72kg) guys\girls can use smaller gear,with less drag and resistance,and there are those whom are ligthweight and fast so it's possible.. But i believe if we rig a race sail,to the specified settings, the weight'ier guys will get more range from each size, no matter how strong my legs are i do not have the force to get the lech pumping and mast flexing and bending as a 20 kg heavier guy?! I have not come to any conclusions on the matter, i feel that on bigger gear, with stiffer masts i tend to be overpowered earlier than the average big guy compared with small gear and softer mast.. For the two last seasons,i've been using point-7 sails,they rig with long extensions and short mast for each size and i think it's a good match for me..

I can remember Nik Baker saying that height had a big influence on sail design. He was developing sails in Australia and the other tester was much taller and heavier (cant remember who it was). He said on some sails the other sailor could be really comfortable on a prototype sail, but Nik struggled to handle it.

The centre of effort of the sail (ie. where the average pull point is) will have a big influence on how the sail feels.

Sail makers tend to have a powerful range which may suit the bigger sailor better eg. the Gaastra Poison, and a lighter feeling sail eg. the Gaastra Manic. I would expect lightweights to prefer the lighter feeling sail.

I'd like to beleive that .It makes my ego less bruised..

mmm..Maybe I'll try that for my 5m..run the 400 on it & see how it goes.I think I'm already doing that with my 6.6m ( 430 + 30cms ext)
