One alloy mast, two wingsails, 50,000 miles

    I've just posted elsewhere on my plan to make a new sail for Tystie. If all goes according to plan, I will have a mizzen mast, 175mm dia x about 11m (I think), 50,000 miles old, for sale; and two wingsails, same age, and their battens, 2 years old, to give away. All as-is, where-is, in the N of New Zealand. Transport would be difficult or impossible; but the Hauraki Gulf ought to be a good hunting ground for a boat to convert.

    A good home has been found for the mast - but there are still two wingsails and their battens to dispose of. The sails are old, and not worth shipping out of NZ; the after, straight parts of the battens can be duplicated anywhere; but the wishbones will be useful to anyone who is interested in wingsails, as the hardest, most labour intensive part of the rig to make. They are still available, free, to anyone who will arrange collection or shipping.

    I may have I missed it, but have you already given your thoughts on moving away from your wingsail?

    After all your hard work, it does seem a shame if the hardware goes to waste, hope you find a taker.  If not, and shipping was reasonable, I would raid my piggy bank, it could clutter my attic until that magical day when I am ready to build / convert.

    What range of sail areas are the wishbones suited for? I'm in the process of converting this winter and I've dismissed wingsails because of the engineering involved, but if I could get ready-made wishbones (shouldn't be too expensive to ship from NZ)... I'm looking at something in the 35-40m2 range.

    After my recent adventure, I must admit to a certain nostalgia for my wingsails. They were easier to handle, and a fan-up was impossible!

    The components were left in the custody of David Thatcher in NZ, and I told him that if he got tired of them cluttering his yard, he could take them and sell them for scrap. The first thing we have to do, then, is to ask him if they are still with him.

    The mizzen wishbones are suited to a chord of 3600mm, and the mainsail's wishbones are suited to a chord of 4500mm (measured over the flat sail, luff to leech). I spaced them vertically at 1300mm. Either could give you somewhere close to the area you need, but if you used the mizzen wishbones, you would have to go for a high aspect ratio rig. I see that your boat is 27ft long, and looks fairly stiff. I'm not sure which size of wishbone I would choose.
