    A little more tension may sort that... but it will soon be academic as you'll have a new sail... and new problems! :-)

    But I might point out, that while the PVC tube stops chafe, it is still rather noisy.  Not something that would bother you, Paul!! :-)

    Arne, where do you feel there should be chafe protection? 




    Where the battens rub against the mast. By using pvc-cloth and (next time?) even padding inside the fore batten pockets, both noise and wear should be eliminated.

    PS: I have, so far, not had problems with chafe from lazyjacks and the mast lift. Even so, the low end of the mast lift for Ingeborg's sail was made from 50mm wedding to spread the load and avoid cutting into the sail bundle.

    Yes, I like the silence of my current system. The old sail which had no cushioning used to market a terrible banging and crashing. It is only when we have discussion that I realise that there is a complete absence of banging and crashing with the new sail. I also keep my batten parrels very tight and that also probably helps.

    Is there a discussion of the merits of the various batten pocket construction methods anywhere, or a go-to location for illustrations thereof? A site search reveals snippets but I haven't found anything comprehensive. 

    Has anyone noticed any chafe of the pocket caused by the batten? The 'D' shape pocket David advocates for offshore use (I found that!) looks robust, but is it overkill for Fantail?

    Fantail does suffer from banging and clattering of the battens against the mast. David, can I please borrow Alison's exercise mat when you've replaced it? Sounds like an excellent idea. Fantail's helm stays light no matter what; I don't feel a need to try canting the sail. 

    Paul, you may have a magic touch. There's some degree of puckering on Fantail's sail where it isn't supported by the batten pockets.

    I've now made a fair number of junk sails and to date I think the simplest, quickest and most convenient method of doing batten pockets is Arne's method A.

    You can add padding if you want before you attach the pockets or you can use split PVC tube. I use spilt PVC tube and it has worked perfectly for me. I've had zero issues.

    I also no longer make continues pockets but make them around 300mm with 200mm gaps between, this makes it easy to insert or remove battens when not on the dock. I make the pockets relatively loose now as well so that a repaired batten can still be inserted in the pocket.

    On our sail we have padding sewn onto the batten pocket which was done prior to sewing the batten pockets onto the sail. We used strips of high density foam, (yes, I know it was Alison's exercise mat, I really must replace it sometime!). The foam was covered with seat-belt webbing which has stood up very well so far and overall this was a good solution to the cushioning of the battens. I never get any of the clanging of battens or yard against the mast. The same method was used for the yard which is also in a sleeve.

    Have you ever felt the need to cant the sail across the mast to reduce weather helm when reaching or running? If so you could put the window in the batten pocket at the mid point of the battens and use very long batten parrels which provides a lot of options in just where the sail will sit on the mast.

    Bryan.

    If I were to make the sail by using the shelf foot method, I think I would sew D-shaped batten pockets onto the lenses before assembling the sail, like David Tyler suggests.

    I see 2-3 good arguments for this:

    ·         One can make proper gaps for the batten parrels and/or HK-parrels.

    ·         One can make the foreward batten pockets from a stronger, more chafe-resistant material, like pvc, as I do.

    ·         One can even make the foreward batten pockets wider so that the battens can be padded at the mast, to reduce noise.

    A 'bite' could be cut on the shelf half tbat faces the mast prior to stitching to give the parrel access to the batten.

    Because the pocket would sit flat during assembly, the forward section could easily be oversewn with a stronger or more chafe-resistant material, and likewise padding could be easily stitched over the pocket.
