Why is the boom cut out so high on the sleeve?
I bought an NCX 7.0 a few weeks ago. Rigged it with the boom about the middle of the cut out and found it was almost overhead when I got on the water.
When I measured, the bottom of the cut out is ~115cm from the mast base. On a NP 6.2 it's ~105cm.
Are all Severne sails made for tall people?
Also, why is it left handed? When I'm rigging, instead of left foot on the mast and right hand pulling the downhaul, it works the other way, right foot and left hand.

Are you using a severne extension with the inline pulleys? Severne extension with severne sails is the way to go.
The pulleys are aligned. And the cleat in the right spot for left leg right hand downhaul.

So you might be losing a couple of cm as the base if you're using a brand made to rig on starboard tack (like np)

Also these extensions have the cleat for rigging on starboard instead of port which twists you up.

I have a severne extension. Why is the cut out so high?
On checking the mast bases, I do seem to have written the reverse of what I meant. But Severne still feels left handed

Yes Severne are opposite rigged than other sails. It'll be weird going from Ezzy or Goya or other brands because you have to lay the sail on the other aide and the pulley blocks are different, etc.

You guys with only one wind direction are funny

Yeah, totally agree Mr Milk. Why I stopped buying Severne, particularly the NCX model. Using the sail with the boom clamp hard pressed on the bottom end of the sleeve is probably not how the sail is designed to operate, and I like a nose level boom height (28cm lines). I can only think the sail is designed for 6 foot users with seat harnesses, or waist harness users with very long lines. I can't use a waist harness due to a childhood back injury.

I'm 6'0" (but shrunk with age) and have my Overdrive right in the middle with 32 harness.

How tall are you?
Sounds like you might have left too much of a gap between the sail and mastbase?
Severne sails tends to rig well right at the markings of the sail, if you are using severne masts and extensions.

I'm about 175cm (about 5' 9" ?) and usually have the boom about halfway between the center and top of the cut-out. Except for Formula sails above 9 m^2 where I'm often at around the centre of the cut-out, but never below.

For the downhauling you have the left foot on the extension and the right-hand on the line, works fine to me. :)

6'6 and I have my boom as high as it can go in all my Severne s, wish the cutout was higher

177-8cm. Lines are 32". (that's another question. Why do we measure boards and sails in metric, but lines stay in the old money?)
Sail is downhauled all the way with the leech loose all the way to the boom

That's why I sold all my Nashes and went Severne, to get the boom to normal height for me. I would beg Severne to keep it that way haha. It's like buying wetsuits if you not in standard height, options decrease 99%.

From what I've heard Severne sails are designed in WA and rigging the sail with the clew on the right suits the prevailing wind over there.
As a short person ( 157cms) I used to find the cut outs too high and had to run the boom at the bottom. When you rig the OD's on a concave decked Isonic it brings the boom to a better height.
They partner with Isonic boards..
