    Ah, she looks so sweet!  They are lovely wee boats.  I can't wait to see her under sail.  Send us some pics and 500 words so that we can make her the Featured Boat on the website!

    And the sail is almost ready!

    He Arne,

    I think we stick to the "traditional" way this time. But we copied your masthead idea, thanks for that!

    Your sail looks good in my eyes, except for one thing  -  the way it is tilted forward. I have been careful to rig my latest sails with a vertical leech, or even leaning a bit aft. This, combined with avoiding battens protruding from the leech, has ensured that the sheets never catch the battens or boom in a gybe, or when tacking.

    Now I took the liberty and grabbed a sail from my stack of master sails (AR=1.85), and then crimped and superimposed it onto your rig, so you can see what I mean.

    I know that Hasler and McLoed used to tilt their sails forward, but after having sailed with a sail this way, I now try to avoid it, if I can.

    Anyway, good luck!

    Arne

    All good, Frank. I can't see anything that I'd want to change.

    That's encouraging, thank you :)

    The six panel sail would look better if the lower three panels were made wider - somewhere between the first and second drawings.

    That is a good point I think. The transitional panel with the altered angles doesn't look quiet right because of the luff width. After that I had the idea to just use 3 head panels. I scratched my head and couldn't find any cons then the more weight from the extra batten and the more work sewing another panel. But I bet that there is another drawback. If not I would go with the plan with 7 panels.

    Frank,
    With a low AR sail like this, I would certainly adopt a transitional panel, the third one from the top, so as to make the top two panels a little smaller. Try rotating the top sheeted batten by 10˚ or so, and the topmost batten by 5˚ or so. This doesn't affect the amount of batten stagger, but does even out the lengths of the leeches and the areas of the upper panels.

    Now with the forthcoming winter we have done most of the epoxy work and did a final measurement of the mast position with the finished partners. Unfortunately the CE needs to be 30cm more aft compared to the first drawings. This gives a lower aspect ratio which I tried to compensate a little bit with wider lower panels because it looked a little bit inelegant and we'll have a too long pole anyway. The sail area would be 25m² which is 13% more than the original BR area. 


    So this could be some sort of final sail plan or at least we are nearly there. Does anyone have any concerns or would you do something different?
