    Paul,

    I’ve received a few remarks about that ‘untidy’ gap between the forward and aft batten pocket. It is the way it is, and is not a result of any stress, so I just disregard it, and suggest you do the same. The actual batten panels on your photo set better now with more camber in them.
    Maybe I should write a few words about it in Chapter 7 of TCPJR, if I bother...

    I am looking forward to reading more reports from your Sweden cruise. Sweden it THE Maxi 77 country, so you will no doubt receive a lot of comments.

    Cheers,
    Arne

    Arne, thanks for the hint! I now did as you suggested, and released the quite tight batten tension by 40 mm. Now it looks a bit untidy and cramped just at the gap of the batten pockets. This straightens above F3 quite nicely, and only affects the aesthetic eyes below that. It still draws the Maxi forward as hell, even in low winds. Even better now with batten tension released, as it increased the camber.

    Paul S’ shown GPS track from his Maxi 77 looks very good. However, it is hardly surprising  -  after all, that sail is a straight 1:1 copy of the blue sail of Boudicca, last month’s BOTM. Boudicca sails well, and her four lower panels actually happen to be 1:1 copies of those in my Ingeborg’s sail.

    That 35.4sqm sail area on the smaller Maxi, brings the SA/disp. up to almost 22.

    Paul; in your photo I notice a horizontal crease along each of the four lower battens. In case they have not disappeared by themselves, I suggest you ease the tension in the sail with 20-40mm along these battens.

    Cheers,
    Arne

    I mean, look at this. Incredible!

    The track is amazing !

    I recorded it as a proof of headwind performance.

    Dare I ask how much you paid for your mast?

    Hi,

    the last two months had been incredibly busy with boat renovation, junk rigging and travel preparations. Yesterday we left Kiel for our 5 month trip up the swedish east coast. I hope and am pretty sure that in the next weeks I will find more than enough time to write more about my junk build and its sailing performances.

    Already a huge thanks to all the hints and shared experiences in this forum and the JRA, very especially to you, Arne!

    As a little teaser, see the foto attached. As soon as I pull on the halyard, a huge smile inhabits my face. It stays until the sail is down again!


    Cheers,

    Paul

    Thanks Arne!

    I had this in my mind, but was glad to be reassured by practical experience.

    Paul,

    don’t make a big problem out of a small one.
    The bending moment in a mast is highest at the partners and next to nil at the ends.
    You may well drill a hole in the mast just above the mast step. I drilled two 8mm holes and ran a rod right through the mast . The rod was then lashed down to the mast step on both sides of the mast. No big deal.

    Keep up the good work!

    Arne
