Split Junk, Cambered panel or hinged batten sail. Which to choose?

    This topic just gets more and more fascinating.

    Two points:

    Columbie egg, Arne?

    I know I lead a sheltered life but even Google defeated me on this one. Setting aside the helpful but hopefully irrelevant references to a Columbia egg donation programme (which I was too nervous to follow up) I found only a video narrated in Norwegian which, because of my linguistic failings, was no assistance. I will be grateful for your advice, please.

    Second, do I remember a posting suggesting that photographs of various rigging styles and tips would be useful? Could this be linked to the picture re-organisation suggested?

    Somewhat at a loss to see how this could be done. Links to an a alphabetical list perhaps?

    I have studied sketches of Slieve’s combined ‘spanned batten parrel/ downhaul’ . To me they are a real columbie egg, doing 3 jobs in one go:

    1. They clanp the batten close to the mast. Less mast tapping in a seaway.

    2. More important, they lock the batten in a fixed fore-aft position - no need for luff hauling parrels or HK parrels.

    3. They keep the luff taut, even on the lowest panel.

    In my eyes Slieve’s Downhaul moves the whole Split Junk up from the "interesting but awkward" category to the "interesting and practical" category.

    Bravo Slieve!

     

    Cheers, Arne

    I used something very similar, with the same benefits, on my wingsails. I see no reason why they shouldn't be a good thing on the lower battens of any junk rig sail which is supposed to go up parallel to the mast.

    I have studied sketches of Slieve’s combined ‘spanned batten parrel/ downhaul’ . To me they are a real Columbie/Columbus's egg, doing 3 jobs in one go:

    1. They clamp the batten close to the mast. Less mast tapping in a seaway.

    2. More important, they lock the batten in a fixed fore-aft position - no need for luff hauling parrels or HK parrels.

    3. They keep the luff taut, even on the lowest panel.

    That is another of the things I like about my sail.
    I have photo of Jester next to Amiina on my wall.
    They have the same genes, but Amiina has evolved!

    Edward is using a simplified version of the ‘spanned batten parrel/ downhaul’ information in Chapter 11. If you look at the third, fourth and fifth photos in the website photo gallery you will see that the red slippery line is tied to the batten behind the mast, goes round the mast, over the batten and down to be spanned with the batten below. The actual downhaul line has a nylon thimble (for cheapness in experimentation) pulling the span downwards, and is only ever ‘tug’ tight. You may notice that Edward has placed some short lengths of PVC plumbing pipe as parrel beads on the batten parrels.

     

    It’s difficult to see how it can be made simpler/ cheaper/ more reliable than this. It gives a very stable and secure rig in lumpy conditions.

    KISS.

    I can't find them, Edward, although Jonathan obviously could.
    With her novel Slieve designed Downhauls there is no possibility of that dreaded fan-up that Junkies fear.
    And would you be so kind as to point me in the right direction to see these clever downhauls, if it's no trouble?  Excuse my apparent sloth, but I'm trying to put the hours in on Fantail and don't really have the time to rummage through Slieve's info to find them.
