    The definition of stupid has got to be the belief that more guns will negate the bloodshed done with guns.

    How is it that a parcel can take less time to come from NZ than it takes money to clear into PayPal?

    Seems they took the same amount of time, one week.

    The boom all sanded back and clear finished. I used a finish called KBS Diamond Finish Clear.

    This is the collar I plan to use to lift the mast a few inches so I can rotate it a couple of inches.

    When I made my sail I went with webbing loops for the battens instead of pockets, mainly because at the time I didn't feel confident fitting them. The sail works quite well but I've never been happy with the slack between the sail and the battens because of the loops. So what to do about it? Well I've decided to fit full length pockets. Today I tried a test run and in amongst my scraps I found two test run samples with loops fitted from when I was making the sail.
    So this is the sample with loops.

    This is the sample with the pocket fitted.

    And this is both with a batten fitted, you can see the difference.

    That really seems to tighten things up nicely.

    Spent the day sewing strips together for the pockets, it’s not going to be a fun job. I’ll post some photos later.

    The pockets will help to stabilise the sail but you'll still get folds and creases in the sail unless you can stretch the sail along the batten with a tensioning strap or buckle. Sailboard sails have very good systems for this that could be applicable to your setup, although you'd want a lot less tension with your sail material. It would be quite easy to set up. A bit of webbing and some plastic buckles. Are you sewing in any reinforcing webbing into the inward end of your pockets? What do they land on now?

    Rick I usually tension up the sail to the batten ends using 6mm braid. The original thinking that I went was not tension too tight. However that has changed and my JR “guru” now tensions his sail. There is a webbing loop on the luff and the leach bolt webbing so other than a folded hem fore and aft on the pocket there should not be added pressure in that area.
    Is that what you meant?

    Well, to get reasonable tension along the batten (i.e., across the sail), you need the inward end of the batten to be pressing into the luff or edge of the sail. If that's not reinforced with webbing or something, it'll tear the end out of the pocket or the edge off the sail. Usually webbing or similar is used to make a little pocket there for that reason.

    On the outer end of the batten pocket, there's a webbing strap or whatever that can be buckled up or something to force the batten against the luff of the sail and hence tension the sail. Sailboard sails are tensioned up so tightly that the batten curves and puts camber into the sail but that's a lot more tension than you'd want.

    It doesn't matter whether it's a junk rig or anything else, you want a smooth sail. Any creases are going to reduce the efficiency of the sail as they disrupt the flow of air across the sail so it's certainly worth making sure you can achieve adequate tension with your battens and adjusters.

    The luff and leach have a layer of 50mm webbing on each side, stitched to that is a webbing loop for tensioning the sail. So I think I’ve got that covered.

    Okay my sewing room.
    8C41F61F-0D7B-4171-9F0D-4972DC07264B.jpg

    Each batten pocket is made up of three strips sewn end to end. So may two strips in top of each other and mark a 50mm line in from one end...that will give a seam 25mm wide.

    Fold and run a line of stitching down the middle. Fold the top layer back over the seam and run a line of thread down the edge of the fold.

    Now do that another 35 times.

    The next step is to hem the edges of the pockets. Once again I drew a line 50mm in from the edge to allow a 25mm hem. I then stapled the hem every 150mm or so just hold it in place.

    5940EAED-1337-40BC-9F73-3AA40B8C9736.jpg
    To hold the hem I ran one line of stitching down the center.

    By this stage I'd had enough, so one hemmed and 5 to go.

    These pockets will go from the leach to aft of the mast position, leaving a gap to allow for the batten parrels and then a short pocket to the luff. I'm not sure of the exact measurement for the gap yet...soon.

    Rick if you look closely at the aft end of the bottom batten you will see a loop around the batten and just above it another webbing loop for attaching the leach of the sail to the batten.
