    Friction in halyard and sheet.

    This weekend I got the idea to write a note about the sheets and halyards I have used on my junk-rigged boats. The focus is mainly on the friction in them, and how I have tried to reduce it.

    Seven pages, no great prose; it looks a bit like a texted album.
    Thanks to Graeme Kenyon for gently making my limping English easier to read.
    The note sits at the bottom of the Technical Files on ‘my page’ ;

    Here is a direct link to it.

    PS, 21.12.23:
    In the first diagram, the halyards are shown with a very wide halyard angle (with respect to the mast). This was just to make the drawing easy to understand. In real life I avoid such wide angles.

    I have just re-drawn Badger's sailplan. The sails are mainly like the originals, but the foresail has been divided into 7 panels instead of the original 6.
    In addition, camber has been added (choice of two cambers).

    Updated "Junk rig for beginners"

    Now I have updated the Junk rig for beginners write up. Most of the update sit in the 4-page Appendix. Only minor fixes have been done to the main section.

    Appendix to last summer's "Fixes, adjustments..." write-up.

    It is about the sheeting.

    Scott,
    there no doubt exists some lashing method which is ‘right’, but I cannot say which one, so I just jazzed together something.

    The lashing has to solve two problems:

    • ·         Prevent the slingpoint from sliding up or down on the yard.
    • ·         Prevent the yard from ‘capsizing’, that is, so that the shackle (with the block) moves down one side of the yard.

    I cannot in detail say how I did, but the main thing was these three steps:

    • ·         First I added friction tape to the upper and lower side of the yard (that black tape).
    • ·         Then I lashed the shackle to the yard with several rounds (not very taut) and secured the end with a few half-hitches or whatever.
    • ·         Finally I took some white, thin, waxed twine and lashed several rounds ‘around the neck’, right under the shackle. This tightens the main (yellow) lashing and ensures that the shackle will not move. Actually, I think this last lashing consisted of a number of half-hitches.

    Clear as mud, right?

    Arne

    PS: An alternative to friction tape is to paint the area with 2-pot paint and then sprinkle it with sand to make a sandpaper surface. Even low-quality rolling hitches will stay put then.

    Hi Arne,

    Thank you for yet another helpful write up. If your written English skills were ever a problem, then this is no longer the case. I will let you know if I have any suggestions. So far everything seems clear and error-free. The photos are very helpful as well.

    I wonder if there is there a specific knot or method that you used to lash the halyard blocks to the yard. I would like to do the same thing with my rig. I have not been able to find any clear description of how to lash a block to a spar online. I expected something to pop right up on google, but that was not the case.

    How do I lash a block or shackle to the yard?

    Frederik,
    I used a double block, up there  -  that is, I intended to, but the chandler was out of doubles. I therefore bought two singles and tied them together and to the tip of the batten.

    The idea of using blocks was to minimize friction. By tying them to the end of the battens, they would never hit my nose in a gybe...
