    Thank you, that's exactly the one I referred to.

    I just upgraded my Word-file with links to interesting topics on this site.

    It sits in my Dropbox folder. You find the link to it on the bottom of my member's profile page.

    I hope this is the one you mean...

    Arne

    PS:
    In the heading of that file I warn that many of the links have died due to 'upgrades' in Wild Apricot. However, when testing the links today, it seems that they work just fine, so the problem must have been sorted out.

    Recently I stumbled over Arne K.’s Link-Sheet, in which he points to several interesting threads. In one of those, from 2013, Paul T. writes:

    Another line that can help to control "Fan ups" is a fixed batten parrel on the yard. The batten parrel will not prevent a "fan up" but in the event that it should happen, it will limit how far forward the yard could go.

    This line is a standing one (ie. fixed) so it does not add to the number of lines that you need to give attention. it also helps to keep the yard under control when hosting or lowering under difficult conditions.

    - Paul T., 2013

    It appears that we recently tried to reinvent the wheel when fitting the yard parrel to Ilvy

     

    May I ask, what happened to the “fan-up fence” concept? I know it was suggested eleven years ago, but did anyone install and test it? Looks promising to me.

     

    PS: I again lost track to Arne’s Link-Sheet, and can’t find it again. Also, it appears to me that the search function of the forum does not include the Yacht Club Bar…

    Then it dawned to me that this reefing problem of yours only shows up when sailing on flat water. I therefore suggest that you just round up for a second and reef the sail while spilling the wind, and then fall off again to the original course. On flat water there is no risk to the boat and little risk for even spilling any coffee.

    My THPs (on several boats) have also occasionally done second duty as downhauls. A quick tug in it is usually enough to free the sail. There is less need for it now, after I shifted the halyard slingpoint of my two last boats somewhat aft of the middle of the yard.

    Yes, it really was a flat water issue. Still, something to keep in mind... don't we all hope for flat seas from time to time :-)

    PS: I have fitted that yard parrel, YP onto Ingeborg too, now, but haven’t sailed with it yet...

    Interesting! Let's see how it goes.

    It’s amazing to see all the developments of the rig that is taking place here!

    I will also improve my rig with your brilliant YP.

    Thank you Paul!

    Interesting reading, Paul!

    Now I was about to suggest that you add a downhaul to the two lowest battens, which would involve only one hauling end. This is an optional extra, which PJR suggests for offshore work.

    In the other thread "camber and induced drag", I've been recently writing about my thoughts to further simplify the rig by removing HK parrels and the THP.


    After yesterday, I do need to rethink!


    We've been steaming along, dead running, at 7.0 kn for some dozens minutes. That is 1.7 kn above hull speed. It felt well under control, Ilvy behaved as usual. I constantly checked bending of batten #3, but is was fine, I've seen it bend worse. All was good - and fun!

    Being close to a windward shore, the sea was perfectly flat. The opposite of what the topic of this thread describes. Approaching a narrow buoyed seaway, we reefed to slow down. The sail came down a bit: the upper battens and yard went down, but the lower ones not so much. The sail "folded" over it's entire height. It was not a bad thing, still able to be sheeted as normal. But still, not properly reefed. I repeat: though we've been fast as h***, there was barely any roll movement in the boat - and no waves. This, combined with a LOT of pressure in the sail, finally illustrated the limits of easy reefing. Normally, the waves and rolling motion of Ilvy would have brought the sail down rather quickly! 

    We used YHP and THP to bring the sail down to the designated reef: pulling and let go of those two, one by one after each other for several times did the trick. I was glad to still have the THP.!

    That was a rather special occasion, and wouldn't have happened if we didn't push Ilvy that far to the limits. Anyways, I am healed now about wishing to omit the THP. To handle that one more line is a compromise I could live with - until someone comes up with a better concept.


    Cheers,

    Paul

    I've always used a yard parallel and never understood why others did not. Although I have rigged mine to the forward end of the yard.

    This looks like an excellent innovation!  I shall try it myself.

    Will the yard parrel replace the fan-up preventer?

    Good, Paul,
    this was what I hoped for. I will fit such a yard parrel (YP?) on Ingeborg’s sail as well. I still have this Fan-up Preventer, FUP, but I hope that the new YP will tame that yard enough so I can wait with touching the FUP until after hoisting or reefing the sail (..for extra safety...).

    May I ask; have you fitted a FUP to Ilvy’s sail?
    (Edit: Yes, I could spot it now on a video clip...)
    Cheers,
    Arne

    PS: It’s sooo good to have a competent test pilot out there...
