    Arne - what a fascinating little write-up.  You looked very happy sitting at the helm.  Lots of food for thought - there are those who reckon that the original FB is the fastest of all the variations.  But it's amazing how well La Barca performed with so much less sail area, when the wind was free.  However, how many sailors ever go to the trouble of adjusting the camber of their sail when they are sailing?  So you had a top-notch boat to sail against.  All very interesting.

    BTW, your chartlet explains why you love sailing so much in your home waters.  What a delightful-looking cruising ground!  And talking of delightful, La Barca is so beautifully cared for.

    Sounds like it's time to make another sail!

    Yesterday we had a little test race between my IF Ingeborg and a standard Nordic Folkboat.

    I made a little photo write-up, called "Testing Ingeborg against La Barca"

    Finally, a week ago Ingeborg received her Fan-up Preventer, FUP. It is made in the same way as the FUP I fitted for Frøken Sørensen in 2014. This time I have beefed the boom up to the same section as the two upper battens (50 x 1.5mm) to let the FUP and the Tack Line, TP, hold the boom down a little without bending it.

    A quick question - what is the line that looks like a mini kicking strap?

    Congratulations, Arne!

    That line (with the rubber snubber on it) is actually the tack line, TL. By attaching it a bit aft of the mast, it ensures the boom will not be pulled aft. No big kicking strap effect from it, but on Ingeborg, the boom is actually built a bit stouter, to the same dimension as the two upper battens (50 x 1.5mm). This is to help the Fan Up Preventer (FUP) work well without bending the boom. The FUP is not yet on.

    Before that very outing I shortened the TL 10cm to bring the boom a little lower. That appears to not be the smartest move. As you can see on some of the photos, both the topping lift and the mast lift cut into the lowest panel. Better let the boom rise a little, so before next trip I will adjust the TL back to the previous setting.

    Here is a link to a 40second/57MB video clip showing Ingeborg sailing. No Oscar for either the actor or cameraman, but at least you ca see how she looks. Ingeborg is steering herself during the first part of the clip, until I undo the tiller lock and alter course.

    I guess you can play the clip directly, but it will have higher resolution if you download the file, and then play it on your device.
    Now, let's see if it works...

    Annie,

    maybe I have grown to be a half-decent helmsman after all these years, but I think it is more the boat than the man this time. When I had Johanna, I sailed a couple of times in company with a Nordic Folkboat. When close-hauled, the same thing happened: The Folkboat sailed 2-4° (I just guess) higher, while Johanna drifted to leeward.

    Last year, during the first trial sails of Ingeborg, she went well, but not that well. Then I thought that I would have a hard time with keeping up with that Folkboat. I must have under-estimated the effect of the moderately foul bottom she had then. Now, after slipping, she really flies in light winds so I guess she and the Folkboat will be quite equal.

    My reasoning behind choosing an IF as a JR project was that I knew about their pointing ability. All they needed was a bigger rig for light winds to overcome the higher wetted surface. Ingeborg’s JR area is the same as the IF with Genoa 1, so is not extreme in any way.

    There is another thing to consider  -  the sheeting and twist.
    Ingeborg has been given the same ‘Johanna sheeting’ as my previous boats (see
    Junk Rig for Beginners, p.5). This has a very good anti-twist effect. As can be seen on the photos, there is just that little bit twist in her sail, both when sailing upwind and downwind. In fact, when sailing close-hauled, with full sail set, I use to monitor the leech telltale of the upper panel. This indicates separation a moment before the others. Keeping the whole sail working, is in my view important to get the best out of a sail.
    The Johanna sheeting takes up quite some room so if there simply is not enough of it, I would split the sheet in an upper and lower part. I think one would be paid back handsomely in performance for the extra complexity of handling two sheet tails, in particular when the sail is reefed.

    Arne

    On the photo below you can see how I tame the long sheet bundle on Ingeborg: A rope loop is lying ready on the side deck so as soon as the sail has been dropped, I clip it around the bundle.

    Gorgeous boat, and great skill in getting her there! Beautiful photos, and just see those tell-tales fly! Thanks Arne!

     Still, we gained on her quite easily and soon we were about to overtake her, when we split up.

    I've had that happen to me - some people really don't like being overtaken by a junk!

    The Marieholm IF,

    together with a 35sqm cambered panel JR,
    plus fresh antifouling
      -
     is a seriously good combination.


    Arne, my friend, I do believe you have forgotten one very important part of the equations: + with Arne on the helm!

    I have to say, Arne, that she is one of the most beautiful, practical, and elegant boats I've seen.
