    Robert, yes, my experience is that the need for HK parrels drops with rising AR. Remember, the sails in Hong Kong were extreme cases of Low AR.

    I didn't see hong kong parrels in the pics but the sail/panels set very nicely. Is this due to the higher aspect ratio?

    This sounds promising, Frederik.

    The yard may drop a bit in the aft end when lowering the sail, but if it falls beyond horizontal, I would be worried. The quick trick if it does so is to haul on the THP.

    The camber and general shape of the panels looks good. I would, however add telltails at the leech of each panel to avoid over-sheeting the sail and to ensure that the twist is right ( with correct twist, all the telltails indicate separation at almost the same time). I would also fit a yard extension stick on the yard and add a burgee/telltale on that one too.

    Keep up the good work!

    First impressions. Still a lot to learn and tuning to do

    Nice on the helm, but will experiment with some more sail forward of the mast. 

    THP on yard only makes the 28 cm luff of panel 1 buckle.  Will try some other arrangement.

    YHP not doing much most of the time  

    The yard does “fall” a bit aft when lowering sail. Slingpoint dead center between the blocks on the yard. When reefing the battens stack fine.

    With 45 cm extra luff, the tack sits low, but I can still more or less see under the boom. 

    Thinking of rigging running topping lifts, mast lift and tack line, so as to take the first reef upwards.

    Tacking and gybing. Easy, smooth. Sheetpoint of pushpit. (For now).

    Have not measured camber yet.

    This sail is not as designed by Arne. All the extra luff. Different top three panels...In my eyes it looks more like a Peregrine kind of sail. Not what I expected. But now that’s what I have, I will try to make it work.

    We had a nice coffee break with the sheets out, just sitting there nice and quiet with 10 knots of wind on the beam.  When we were done, I hauled in the sheet and we were doing 6 knots in 10 seconds.....

    Looking good. I notice that the sail is set with moderate balance, but with 20cm shorter battens than on my Ingeborg, she should still balance fairly well on the helm. 

    One thing I have thought of is to move the topping lifts about 50cm forward on the boom to get more clearance for the yard when deeply reefed. On your boat that would be very easy, now before you fit the sail catchers and sail cover. On Ingeborg, that job would mean recutting the sail cover and maybe moving the sail catchers as well, so I will probably not bother, but rather rely on my FUP and yard extension stick.

    Arne

    PS: Any sign of the yard dropping at the aft end when lowering the sail? On the rather tall (in my context) sail with AR=2.0, you should get away without that problem, even with the slingpoint moved forward to the middle of the yard.

    The smile says it all!

    Just a little more of a pull back on the throat, and then it will look really good.

    Now I know....

    First ruff & ready sail with “kinøjser” rig.

    An epiphany.

    Arne. 

    Hmmm ja...

    I’m in contact with Tuchwerkstatt and try to figure out why the sail is so different from your drawing.


    Had a quick look at the sail this morning after adjustment of the THP only working at the yard. Looks a lot better now, but still not much drift left with the sail 50 cm over the deck at mast position.

    I’ll see if  I can get away with moving the halyard blocks on the yard further forward and set the sail with 40 cm boom-deck

    I’ll take a measurement of the total luff length tomorrow

    Frederik,

    This appears not to be an uncommon problem. I had a local sailmaker sew a new sail for my Johanna, back in 2002. He screwed up completely and had to do it all over again. It surprises me that the Tuchwerkstatt makes such errors, though, since Sebastian has made so many junk sails. Could the job have been left to an apprentice without sufficient supervision?

    Anyway, this is why I encourage people to make their own sails, and that is why I still ‘sell’ the simple barrel cut method: This method lowers the step from the armchair to the sewing machine.

     I claim that anyone who has never ‘set foot in’ a sewing machine can gain the needed skills in two days, with a bit help. During those two days one learns to adjust the thread tension, how to start and stop (!), and by making a couple of sail bags or shopping bags, one soon learns to make the seams straight enough. I know about no other (legal) homework, which pays back better than making my own sails.

    The sail can probably still be used (good that you made the mast a little taller), but you should have a serious talk with Sebastian. He cannot be proud of that job.

    Arne

    Arne. 


    You were not wrong. The luff of the first two panels is ca. 28 cm. See picture of the two from head of sail to center batten 6

    Luff Panel 3 measures to 63 cm

    The other 4 panels 112 cm 

    According to you drawings the numbers should be 14, 56 and 107 cm. 

    Quite a difference. There is not much drift left between halliard blocks with the slingpoint already moved to dead center of the yard.  The boom just 50 cm over the fore deck at the mast position... LAP is a generous 890 cm.


    Hmmmmm.....
