    Arne, 

    Happy constitution day, and all the best to the norwegian people!

    Excellent points of yours! I also find the groove of optimum angle of the junk sail to the wind quite narrow: I'm mostly either pinching or sailing too low. I think it doesn't help to have webbing sewed in at the luff - I expect boltrope would widen that groove. Anyways, the sail is now as it is, but I'll take it as a learning for the next sails.

    You remember that tufting experiment on Ilvy last summer? Those telltales, spread all over the sail, definitely helped a lot - though I could only see the lee side telltales of the sun was on the right side. Sewing in some telltale windows would help here, but then we are talking about some fancy-schmancy regatta stuff :-D

    I fully agree about the importance to give enough time to accelerate after a tack!


    Today we had pretty much exactly the same conditions in the Kiel fjord at the regatta on wednesday: NNE F4-5.

    I headed out for some training, trying to stay in the groove while sailing upwind. Turns out, Ilvy's tack angles/ angles to windward werr still not too good. What did I do wrong? How did I manage to get to almost 90° in Sweden last summer?

    Then I got distracted from shooting some videos of the tacking manoevre of a junk rig. I did a lot of tacks, but focussed on filming. After that session, routinely checked my GPS track: Wow! Now this is what I had expected while racing: almost 90° in every tack. Was it possible, that I sail better angles if I didn't focus too much on steering!?

    What an unexpected result...

    Cheers, Paul

    It is only a little week since I had the first sail in my Ingeborg, this year. As always, we are a bit rusty, both in sail handling and general helmsmanship.

    A constant challenge is to get the pointing angle right when closehauled. The telltales may keep the airflow over the sail right, but I may still point too low or pinch too high. I once made an informal ccomparison race against a Folkboat. We stopped the race after each leg and then restarted.
    On the last leg, upwind I struggled. After that I did two things; easing the tension along the battens to increase camber a little.
    I also made a wind indicator with vanes (like on the Windexes). These vanes tell me when I am too low or high, and are especially useful when heading up after a long run  -  or after a long winter.

    Another error is easy to make when tacking, and that is bringing the tiller back to CL before the tacking has been completed. I wonder if this has to do with how we turn our cars. After a sharp 90° turn, we simply ease the steering wheel back to centre. I now make sure that the tiller is fully deflected (varies with boat type) until the sail has actually filled on the new tack. Then I pick up speed over a few boatlengths before, carefully easing the boat back onto the correct course, with a half eye on that wind indicator. Getting up the speed again after each tacking is everything in racing around the cans.

    Good luck,
    Arne

    Hi,

    this summer I'm trying Ilvy for her racing abilities. Two days ago the first wednesday regatta of the season took off. Starting at 1800, it is a fun afterwork regatta, divided in three yardstick groups (The winner of each group has to buy a box of beer for the next regatta!). Ilvy, a Maxi 77, sails at yardstick 116 with her original bermudan rigg. I registered with that yardstick for the races, to be able to evaluate a possible yardstick modification by the end of the summer. Of course my hopes are high that Ilvy's yardstick can be reduced with the junk rig! :-)

    Let's see how my enthusiasm compares to reality... I am not an experienced regatta sailor, and sailed maybe 10 regattas in my life, some on Ilvy with her bm rigg. I have to admit that I needed to look up most of the applying regatta rules on tuesday night.

    The first regatta was raced at northeasterly F4, which means a lot of choppy waves in the Kiel fjord to sail against. Typically, the prevailing winds are westerly, sometimes easterly. Northerly is rare. I sailed single-handed this time, with the boat pretty empty - all the travel stuff from last summer was already cleared out in winter.

    I had a superior placement at the starting line, just by letting the sail feather in the wind and waiting to the signal. However, in lack of a good timekeeping - I only used my phone showing minutes, not seconds, to start signal - I missed accelerating in time, and was overtaken by my whole group right after the signal, which left me last.

    The first leg was upwind, and I saw those folkeboats (almost the same yardstick) slowly sailing away from me. I don't really know what I did wrong, but my GPS track clearly shows that my pointing angle wasn't good. I expect that against the choppy sea, Ilvy's round belly didn't stand a good chance, while those S-shaped longkeel folkeboats simply cut through the waves. Also, I oftenly pinch too high with the junk rig, only sailing by feeling - but when she uprights herself, it is of course too late... Maybe I need to put some luff telltales onto that yellow canvas! Pinching in choppy seas doesn't make one win a race, I guess.

    Also, I kept on the eastern side of the fjord as I hoped to catch some nozzle effect of the northerly wind, while most other boats used the whole width of the fjord. Looking back at it, my strategy probably wasn't the best - though tacking really wasn't an issue at all.

    However, once round the northerly buoy, Ilvy's time had finally come! Dead running, I shook out the one reef I had put in upwind, and she blasted through the water. I rounded the buoy together with one other competitor (not folkeboat), but downwind that boat was pretty soon left on the horizon. However, the folkeboat fleet was way too far ahead to catch up. Anyways, doing 6.5 kn downwind, with the tiller between my knees, I opened myself a beer (non-alcoholic) and enjoyed the ride anyways.


    Result of the day: I was second last through the finish line, but 12th out of 12 yachts according to calculated time. Not exactly what I hoped for, but with potential for improvements!


    To Do's for next time:

    • more weight on the windward edge -> friends are already invited!
    • less pinching -> telltales are already fabricated!
    • use of accurate clock for the start


    I had hoped that the rare northerly wind would be advantagous for the junk rig, as it set on leg to straight downwind. However, I hadn't considered the upwind leg being so choppy.

    Let's see how westerly winds would suit Ilvy in that regatta!


    Cheers,

    Paul
